Mosaic Art Glass Assortment 2-lbs is untumbled shards of American-made stained glass in colors chosen for pigment density and opacity for use in mosaic artwork. We also sell individual colors of American-made stained glass in 6-inch sheets if you need an individual color. Piece size varies, but we try to cut pieces 2 to 3 inches wide, so there should be fewer pieces 1 inch or less. Cutting Scrap will have smaller pieces.
Caution: Sharper Edges Than Molded Tile
Stained glass is usually sharper than regular molded glass mosaic tile, so extra care must be used in cutting and handling and in 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.
Each two-pound bag is approximately 1.25 square feet of glass. If you cut up 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.
The thickness is approximately 1/8 inch and nominally the same as the 3/8-inch and 3/4-inch glass mosaic tile we sell. Some colors of vitreous glass have a more grainy composition than other colors, and these grainy color might not look right when used alongside stained glass due to the difference in glossy finish. The more glassy “No Grain” colors in the Kaleidoscope 3/4-Inch Vitreous look fine when used with stained glass.
