Iridescent Mosaic Art Glass Assortment


2 pounds of American-made stained glass pieces chosen for pigment density.


The Iridescent Mosaic Art Glass Assortment includes a colorful range of stained glass pieces sampling our entire iridescent stained glass selection. This particular mix may include one or two clear iridescent pieces and one ripple texture piece.

Mosaic Art Glass Assortments feature a 2-lb selection of American-made stained glass pieces for making mosaic art. With opaque work surfaces in mind, we choose pieces for pigment density and opacity. This assortment offers a great way to sample and experiment with a range of stained glass types and colors. If you need an individual color, or find one you love in an assortment, we also have stained glass in 6-inch sheets. Piece size varies, but we try to cut pieces at least 2 to 3 inches wide. Cutting Scrap will have smaller pieces.

Caution: Sharper Edges Than Molded Tile

Because stained glass is usually sharper than regular molded glass mosaic tile, extra care must be used in cutting, handling, and grouting to ensure that sharp edges are not left exposed. At the studio, we sometimes cut up sheets of stained glass into tiles and then swirl the tiles around in a plastic bucket with a little water to knock off the razor slivers from the freshly-cut edges (called flash or groze). The Rubbing Stone and Marble File we sell are useful for smoothing sharp edges and are recommended when the mosaic is for a wall or architectural element.

The traditional tool used by stained glass artists for this purpose is the Grozing Pliers, but the Rubbing Stones and Marble Files produce smoother edges and can be used to round off sharp points and corners.

Product Coverage

Each two-pound bag is approximately 1.25 square feet of glass. If you cut these pieces into mosaic tiles of about 3/4 inch or less and use a grout gap of 1/16 inch, then the bag could cover 1.5 square feet.


Stained glass is approximately 1/8 inch thick and nominally the same as most of the glass mosaic tile we sell. Some vitreous glass colors have a more grainy composition than others, and might not look right alongside stained glass due to the difference in glossy finish. The more glassy low-grain Lojee-Nojee tiles look fine with stained glass.

Cutting Stained Glass

Glass can be cut quickly with minimal force using our Mosaic Glass Cutters. Use this wheeled cutter for irregular rectangle and triangle shapes. For curved cuts, use the Pistol-Grip Cutter to score the glass, and a pair of Running Pliers to apply pressure and snap it. You can also use cutting oil to lubricate cutters for more precision.

Mounting Art 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, use thinset mortar.

Iridescent Stained Glass in Mosaic Art

Use iridescent stained glass to enhance realism and impressionistic effects, or evoke surreal qualities in your mosaics. Add decorative edges, beautiful borders or outlines. Bring sparkle and luminosity to bodies of water, extra glow to sunsets, or playfulness and magic to any detail..

Individual Colors Available As 6-Inch Sheets

If you need an individual color of stained glass, we also sell it in 6-inch square sheets. Email us if you’d like help identifying a stained glass color from an assortment.
