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). Use our Quick Order Checklist to order rapidly using
a list which can be sorted by category.
