Price is for 8 ounces of loose tiles.
Each tile is 20mm x 20mm (~3/4 inch x 3/4 inch).
Pigments: colorfast metal oxide.
Solid color throughout.
Coverage: one bag will cover approximately 0.42 square feet when using a standard grout gap of 1/16 inch.
Thickness: nominally 2.88mm, which is about 35% thinner than vitreous glass tile, but appears to be over 3mm.
Suitable for indoor and outdoor installation.
NOT suitable for floors.
Product Coverage
Each bag covers about 0.42 square feet when mounted with a standard grout spacing on approximately 1/16 inch. Use our tile estimator to calculate how much you need for your project.
Compatibility
Tile thickness is nominally 2.88 mm, which is about 35% thinner than most of the glass mosaic tile we sell, but the actual thickness is probably running more than 3mm. Mixed-media mosaics and even mosaic table tops are routinely made from dissimilar materials with even greater differences in thickness. It makes grouting a little more work but not too difficult, and it is a great way to add texture and visual interest to a mosaic.
Cutting Tile
This tile can be cut with minimal force using the Mosaic Glass Cutters that we sell.
Mounting Stained Glass Tiles
For dry indoor mosaics, stained glass can be mounted using Weldbond adhesive, but thinset mortar should be used for outdoor and wet mosaics.
Use in Mosaic Art
Using different materials in mixed-media mosaic is a great way to add texture, dimension, and visual interest.
Not For Floors
Morjo™Stained Glass Mosaic Tiles 3/4 inch is non-porous and can be used outdoors, but we don’t recommend it for flooring.

Sample Board Morjo™ Iridescent Glass Tiles 3/4 Inch comes with one of each tile in our color palette in the 3/4 inch (20mm) size. The Morjo™ brand or iridescent tiles are mildly iridized so that the underlying colors aren’t obscured, which is a plus when creating images. Here is more information about the tiles and how they are used:
Morjo™ Iridescent Glass Mosaic Tiles 3/4 inch (20mm) are sold loose by the half pound (approximately 75 pieces). The backs are plain colored glass with embossed ridges and grooves to help adhesives bond securely. The 3/4-inch width and ~1/8-inch thickness are standard dimensions, so you can mix and match these with many other brands of tile. All our glass tiles can be cut easily with the Mosaic Glass Cutter we sell.
MILDLY Iridized
Note that the iridescence is MILD and not so glossy that the underlying color is obscured. This is a definite plus because glass that is heavily iridized tends to look the same no matter what color the glass is underneath. These tiles show a significant amount of the underlying color and can be used to render polychromatic images.
Morjo™ Iridescent Glass Mosaic Tiles 3/4-Inch
Price is per 1/2 pound.
Tile dimensions: 3/4″ x 3/4″ (A standard size and compatible with vitreous tiles from most other manufacturers).

Mosaic Tile Mesh is 12 INCHES WIDE and 150 feet long in one continuous UNCUT piece. The mesh is made from woven fiberglass and is the same material that factories use for pre-mounting ceramic tile for rapid installation in walls, floors, and backsplashes. Artists use it in much the same way when laying up large designs, but the mesh is not needed for small mosaic art projects or surfaces such as tables where the tile can be glued directly to the surface.
Fiberglass mounting mesh is most useful for backsplashes and murals and floor medallions and other projects that are large or involve surfaces that can’t be monopolized for long periods of time. In these situations, the mosaic design is laid up on a worktable overs an extended period perhaps involving many different studio sessions, and then the finished design is installed in one session for attaching to the surface and a second session for grouting.
Tip: Even if your design is large, you will probably find it easier to cut the mesh up into 1 ft x 1 ft pieces and lay up your mosaic in these smaller sections. Anything larger than 3 ft x 3 ft is just too heavy and unwieldy to mount on a vertical surface.
Product Specifications
material: woven fiberglass mesh
unit weight: 4.3 oz/square meter (standard weight used for tile mounting)

Use a white PVA adhesive such as Weldbond to attach tiles to the mesh.
How to Use Mosaic Tile Mesh
Glue
Use a white PVA adhesive such as Weldbond to attach tiles to the mesh.
To avoid gluing your mesh to your work table, you should use a plastic table or cover the tray in plastic. Construction plastic or coroplast from the building store should work. If you have an old politician or real estate agent plastic advertisement sign from the side of the road you can probably use one of those.
Outdoor and Wet Installation
For outdoor and wet mosaics, it is best to avoid mesh and use mounting paper or mounting tape to temporarily face-mount the mosaic so that it can be pressed into thinset mortar without a layer of mesh and glue on the bottom. This is particularly important when your tiles are small. Mesh can be used in wet locations if glue is used sparingly and your tiles are large enough to safely cover the glue.
If you will be installing the mosaic outdoors or in a wet location, avoid completely covering the bottom of the tile with glue and keep the glue toward the center of the tiles. Leave the outer edges bare to bond directly to the thinset mortar used in final installation. Be careful not to get glue up the sides of the tile. If adhesive isn’t covered with grout, then water can wick underneath the grout over time and cause tiles to pop off. You should inspect the sheet of excess glue by misting it before it is installed. Any traces of glue on the sides and faces of the tile will start to turn white after a few minutes of being misted with water. Use a knife to scrape away any glue residues you see coming up the sides of the tile to face of the tile.
Working Size and Sections
Mesh covered with tile can be heavy and unwieldy, especially when mounted to a wall. You can lay strips of mesh side-by-side if you need a wider piece, but don’t try to vertically mount a one-piece mosaic larger than 3 foot x 3 foot. The standard practice is to lay up the mosaic on 1 foot x 1 foot pieces of mesh and match up the different sections when the mosaic is installed. Floor medallions 3 foot x 3 foot are sometimes made on one piece of mesh, but even though these are mounted horizontally, it still requires that the mosaic be carried on a piece of plywood and slid into place.
Final Mounting
To mount mesh sheets of mosaic to your surface, thinset mortar or adhesive should be spread on the surface with 1/4-inch notched trowel. We “butter” the bottom of the sheet with a little bit of the same adhesive in a thin coat before pressing the sheet into place. Make sure you allow the thinset or adhesive to cure for at least 24 hours before attempting to grout because grouting is a physical process that can easily knock tiles loose from uncured mounting.
Compatibility
The mesh is not used with tiles 3/8-inch or smaller because the holes in the mesh and the ridges on the bottoms of most glass tile make it difficult for small tile to sit level. For small tiles, you should use mounting paper to temporarily FACE-mount the tiles upside down. The product description for our mounting paper explains how that is done.
Use in Concrete Sculpture
The fiberglass mesh can also be used with other materials to make concrete sculptures for covering in mosaic.
Morjo™ Iridescent Glass Mosaic Tiles 3/4 inch (20mm) are smooth, richly colored opaque glass tiles with a subtle iridescent gloss. Each 1/2 pound bag contains about 75 tiles. Embossed ridges and grooves on the back help adhesives bond securely. The 3/4-inch width and ~1/8-inch thickness are standard dimensions, so you can mix and match these with many other brands of tile.

We have a beautiful selection of Youghiogheny brand stained glass in 6-inch square sheets. Use these square sheets to hand cut your own art glass shapes for mosaics. Our selection includes bright, earth tone, transparent, and iridescent varieties, and many types including swirled, streaky, mottled, and textured, for endless possibilities in mosaic applications. Along with High Strike, Stipple, and Reproduction Glass, we also now carry Fusible, Dichroic, Uroboros, Oceana, Granite, Ripple, Modern Art Series, and Textured Streakies all by Youghiogheny.
Youghiogheny stained glass is the highest quality art glass suitable for mosaic artwork currently available on the market. We are very excited to be able to make this premier product available to our customers. Made in the USA.
Stained Glass Surface Finishes
We primarily carry Youghigheny’s High-Strike (HS) and Stipple (SP) glass lines, as indicated in the product number of each variation. Glass labeled RG is Reproduction Glass; these are authentic reproductions of Tiffany stained glass. High-Strike glass is a traditional mottled art glass and looks glossy. Stipple glass is high quality and has a waxy, ice-like effect, with a textured, shiny finish. RG glass usually has a finish that is very similar to the HS glass. The thickness is remarkably uniform at exactly 3 millimeters, which is about 1/8th of an inch.
Stipple Finish Stipple glass has a waxy or ice-like finish. These usually have a degree of translucence to them and are great for use in glass-on-glass mosaics. The surface of the glass has a small amount of texture.
High Strike Finish High Strike glass has a traditional finish, and is usually mostly smooth or glossy. This glass is more likely to be opaque. Reproduction Glass or RG variations usually have the same finish.
Finish Variations in Mosaic Art
The differences in texture and finish between HS, SP, and RG glass shouldn’t cause concern for most mosaic artists. We have used Stipple and High-Strike glass right next to each other in the same projects with spectacular results.
An N in the product number refers to use of neodymium for a strong purple pigment. The letter i refers to iridescence on the face of the glass.
Youghiogheny Stained Glass Sheet 6-Inch
STAINED GLASS VARIES IN COLOR AND PATTERN BY SHEET. Do not order if you cannot tolerate variation.
Sales unit: 6×6-inch square piece
Squares are hand-cut using a straight edge and not always perfectly square.
This is cutting stock for making small mosaic tiles; not intended for use as finished mosaic tile.
Thickness: 3 mm or 1/8th of an inch
Pigments: colorfast metal oxide.
Coverage: 1 sheet covers approximately 1/4 square feet.
frost proof
impervious to liquids
Suitable for indoor and outdoor installation.
NOT suitable for floors. More fragile than glass tile.
Stained glass can have sharper edges than regular molded glass mosaic tile, so care must be used in cutting, handling, and grouting. Stained glass varies in color and pattern by sheet. Do not order if you cannot tolerate variation.
Product Coverage
Each 6-inch square sheet covers approximately 1/4 square feet when uncut. When you cut it up, you will gain additional coverage from the grout gap, but you will also lose some coverage in the form of cutting waste.
Compatibility
Sheet thickness is 3mm or approximately 1/8 inch, which is NOMINALLY the same as most of the glass mosaic tile we sell. That being said, mixed-media mosaics and even mosaic table tops are routinely made from dissimilar materials with even greater differences in thickness.
Cutting Stained Glass for Mosaics
Stained glass can be cut quickly with minimal force using our Mosaic Glass Cutters. Use this wheeled cutter for irregular rectangle and triangle shapes. For long straight cuts and curved cuts, use the Pistol-Grip Cutter to score the glass, and a pair of Running Pliers to apply pressure and snap it. Finally, you can also use cutting oil to lubricate cutters for more precision.
Use as Cutting Stock vs. Whole Tile
We hand cut these sheets using a straight edge, and so there is variation in size and straightness. We sell these square sheets as cutting stock for making small mosaic tiles, not as single finished tiles. Some sheets may have a rippled edge along one side of the glass – this is the outer edge of the larger sheet we cut into squares. For a finished tile option, see our 3/4-inch Morjo™ Stained Glass Tiles.
Mounting Stained Glass Mosaics
First, before mounting always rinse stained glass with detergent to remove any traces of cutting oil residue. Even if you don’t use cutting oil, it may be present from the manufacturer. For dry indoor mosaics, Weldbond adhesive works well for mounting stained glass. However, for outdoor and wet mosaics, we recommend you use thinset mortar.
Smoothing Sharp Edges
Stained glass often has sharper edges than molded glass mosaic tile when cut. At our studio, we use a marble file or a rubbing stone to knock off any razor edges remaining after cutting.
Safety Notes
We have chosen Youghiogheny stained glass for its beautiful quality and pigment density which makes it suitable for mosaic artwork. However, while it is non-porous and suitable for outdoor mosaic art including benches, tables, and garden décor, it is not recommended for tiling floors. If a mosaic becomes damaged on a surface where it could cut someone, then use the fine edge of a marble file to smooth the edge until you can replace the tile. This also applies to mosaics made with molded tile.
Rendering in Mosaic Art
Traditional stained glass art often makes use of custom-cut pieces that define entire figures or components. In mosaic art, the approach is different: figures and components are almost always built up from multiple tiles unless the object in question is particularly small. It is best to stick to one approach or the other for a particular piece of art..
American Made Stained Glass
Youghiogheny stained glass is made in Connellsville, Pennsylvania on the Youghiogheny River. This is quite possibly the most beautiful glass made in the world, including Italy. This is a great opportunity to buy an American-made product and support high labor and environmental standards at a price that is competitive with molded glass tile made in China.

Mounting Grid for 22mm (~7/8 inch) Stained Glass Tile is for temporarily mounting patterns of uncut tile to paper for rapid installation using the indirect method. These are not needed for most projects. Most artists use cut tiles or glue each tile directly on the surface they are covering and do not need grids.
These grids come directly from the factory and show various signs of use. They were made by machining blocks of plastic instead of pressed in a mold, so they look home made to be brutally honest, but they work.
Note that these grids were made for 25mm beveled tile, but they work with 22mm (~7/8 inch) tiles with straight (non-beveled) edges. We decided that the grout gap was too small when used with 25mm tile.
Note that the paper we sell is 1.15 square foot, which is larger than these grids but should not pose any problems. (You can always trim away the excess paper after you mount the tiles.)
Mosaic Tile Mounting Grid 22mm
grid size: 12 tiles x 12 tiles.
grid area: 30cm x 30cm (just under 1 square foot).
grout gap: approximately 1/16 inch.
tile size: 22mm (~7/8 inch).
Indirect Method
Mosaic tile can be glued one at a time DIRECTLY to a surface, or you can lay your mosaic out on a temporary surface in what is called the “Indirect Method.” Temporary surfaces can include things like fiberglass mesh, paper, adhesive contact paper or trays filled with lime putty. Our grids were made to work with self-adhesive mounting tape or mounting paper that is glued to the faces of the tiles.
Why Use The Indirect Method
Why would you want to use the Indirect Method? It is easier to lay up your mosaic design at your work table than it is to lay it out on a floor or vertical wall. Also, you can work for days or weeks at your work table laying up the mosaic without tying up the location where the mosaic will actually be installed. Again, none of this is necessary for a beginner laying up a small craft project like a trivet or a mosaic mirror.
Use In Mosaic Art
The following is how to do the indirect method using our grids and mounting paper:
Place glass mosaic tile into the grid face up, filling up the grid with your design.
Dilute water-soluble glue such as Elmer’s Glue with 3 parts water to 1 part glue.
Paint the water soluble glue onto the mounting paper using a small artists paint brush. Use a light coat to avoid wrinkling the paper.
Lay mounting paper onto the face of the tile, careful to avoid wrinkles.
Allow sheet to dry completely and remove from the grid.
Spread thinset mortar or mosaic adhesive on the surface to be mosaiced.
“Butter” the bottom of the sheet of tile with the same mortar or adhesive. Of coarse, you butter the bare glass bottoms of the tile, not the paper.
Press the sheet of tiles into the adhesive-covered surface with the PAPER ON THE OUTSIDE.
Allow the thinset or adhesive to cure for 24 hours.
Mist the paper until it is soaked and peel it off the tiles.
The 298ml (10.1 oz) cartridge of GE Advanced Silicone 2 is intended for use in a caulking gun. It covers up to 20 square feet depending on surface roughness.
GE Advanced Silicone 2 Window and Door adhesive can be used for glass-on-glass mosaics or for doing mosaic artwork on certain metal surfaces such as a mailbox. We do not recommend Weldbond for glass-on-glass mosaic applications because Weldbond will NOT fully cure when placed between two pieces of glass. Silicone will cure properly and remain clear when used to laminate two pieces of glass, and so it is preferred for that application instead of Weldbond.
GE Advanced Silicone 2 Clear Window and Door Formula Adhesive

Advanced Silicone 2 is a clear sealant and adhesive suitable for wet environments. It is a single-component neutral cure silicone suitable for use on a variety of materials including glass, metal, and wood. It dries with some permanent flexibility which makes it suitable for glass-on-glass mosaics and on mosaic mailboxes. It will bind to many metals such as steel and aluminum. Conforms to ASTM C920.
Advanced Silicone 2 should NOT be used underwater such as in a pool or where water exposure will be continuous, such as in an aquarium. These applications should instead use thinset as an adhesive.
Product Coverage
The 298ml (10.1 oz) cartridge of Silicone II covers about 20 square feet IN THEORY. Actual coverage is about 20% less than that for most users doing detailed work, but messy users or coarsely porous substrates could require significantly more glue. The coverage is greatly affected by how neatly you work and how thick you apply the adhesive.
Use In Mosaic Art
We recommend silicone for glass-on-glass mosaic applications, and for mosaics on top of metal surfaces, such as a mailbox. For most indoor mosaic applications on wood or cement board where no water exposure is expected we instead recommend you use Weldbond.
Limitations
Not for Submerged Applications
Silicone is water-proof when fully cured, but it should not be used where permanent exposure to water is expected, such as in a pool. Mosaics in wet locations such as pools and fountains should be made with thinset bonding mortar (a type of sticky concrete) instead of adhesive.
Other Limitations
Silicone is messier than Weldbond and is harder to work with for this reason. Always have extra rags or paper towels on hand. When using the 298ml (10.1 oz) caulking gun tubes we recommend using a caulking gun with a quick tension release lever on the handle. We carry this product because it fulfills two use cases where Weldbond is unsuitable — glass on glass mosaics and mosaics on metal surfaces.
Silicone should not be used with small children, as it can be harmful when swallowed. We can NOT recommend it be used in a project with participants who are not yet high school age.

Polished Porcelain Mosaic Tile 15mm are 4mm thick, the same nominal thickness as most of our glass tile. They are 15mm (roughly 5/8 inch) on each side and sold loose in bags of 1/2 pound, which is approximately 130 pieces. These are fine porcelain with solid color throughout. The tops are mechanically polished (buffed) but not glazed. They can be cut with our Compound Tile Nipper, and we recommend smoothing cuts in hard materials using the fine side of a marble file. These tiles and very hard and durable. Please note, the polished surfaces still have small incidental pits that can be stained with grout and colorants.
Grout Staining in Pits
Note that the polished surfaces still have small incidental pits that can be stained with grout. This isn’t a problem for our projects, and we have simply ignored the issue in our art. Do not order if this is a problem for your project.
Never Install Tile in Batches
Tile varies by manufacturer batch, and sometimes a color will go out of stock for an extended period if the manufacturer isn’t making it. You should never install tile before you are sure that you have all the tile you need. You could attempt to order more and find that the manufacturer has changed the color or discontinued it.
Product Coverage
Some colors are sold loose in 1/2-kg bags of approximately XXX tiles. Assuming a standard grout gap of approximately 1/16 inch, a bag of 1/2 pound will cover 55 square inches or 0.4 square feet. To cover 1 square foot, you will need about 3 bags. Use our tile estimator to calculate how much you need for your project.
Compatibility
The Polished Porcelain Tiles are 4mm thick, the same nominal thickness of most of our glass tile. They also have a glossy finish similar to glass.
Cutting Porcelain Tile
Polished Porcelain Mosaic Tile 15mm is not soft like most glazed ceramic tile. Porcelain is extremely hard, but it can be cut. Our Compound Tile Nipper is the recommended tool for hard materials like stone and porcelain. A Marble File is also required for smoothing the edges of cuts and shaping the pieces. Exposed sharp edges should be rounded with the file for safety reasons.

Frost-proof, impervious to liquid.
Suitable for indoor or outdoor use.
IMPORTANT INSTALLATION TIPS
For architectural installations, the manufacturer recommends that the porcelain tile be installed with a latex-modified thin set mortar instead of glue. For dry indoor mosaics, we use Weldbond glue.
Porcelain is essentially non-porous and impervious to moisture, and so it is supposedly not stained by grouting, but we have noticed discrete pits and divots in the surface of the tile that can be filled with grout. For this reason, we recommend using GROUT RELEASE (from a building materials store) on the mosaic before grouting:
Mount the tiles to the surface to be covered.
Use a rag or small artists paint brush to apply GROUT RELEASE to the face of the tiles.
Take care not to drip excess GROUT RELEASE in between the tiles or down the sides of the tiles or any place grout will need to bond.
