Toy Glass Marbles
Toy Glass Marbles can be used as a form of glass mosaic tile when pressed into wet cement such as commonly done when making mosaic stepping stones.
However, the marbles are spherical and are not easily glued to a surface like ordinary flat tile. Most varieties are opaque and have brightly
swirled colors. The nominal size is 16mm (9/16 inch), but expect variation. Read more about using Toy Glass Marbles in mosaic art

Toy Glass Marbles In Mosaic Art
Each bag of 30 marbles could cover about 7 to 8 square inches, but marbles are best used as accents in mixed-media mosaics and not as area coverage.
Round marbles don't easily glue to a flat surface, and most glass mosaic tile is roughly 1/8 inch (4mm) thick, which is significantly thinner than the marbles. If you use marbles with glass mosaic tile, make sure you press them into mortar or concrete instead of trying to attach them to a flat surface.
We don't recommend cutting toy glass marbles.

Use in Mosaic Art
We recommend glass marbles for pressing into concrete and mortar, such as when a mosaic stepping stone mold is used to make art for the lawn or garden. Keep in mind that whatever materials you use to make a stepping stone, make sure that you do not leave sharp edges exposed or create a slick surface that could be a slip hazard when wet. In practical terms, that means leaving some bare concrete or grout between pieces of smooth glass.
