MORJO Thinny-Pennies Penny Round Recycled Glass Tiles have a glossy finish, and solid opaque color throughout (not just on the tops or bottoms). Unlike glass gems, another common round tile, Thinny-Pennies have a flat and even surface rather than puffed. This makes them much easier to use with other types of glass tile and easier to grout.

Cutting Recycled Glass Thinny-Pennies

Recycled glass cuts like butter using the Mosaic Glass Cutters without creating a lot slivers or cutting waste.

Grouting Round Tile

Note that dry indoor mosaics do not require grouting, and so for those you can simply mount the tiles tightly together. On the other hand, wet and outdoor mosaics must have grout to prevent water from penetrating behind the tiles. For those, leaving a 1/16-inch gap allows enough grout to adhere between the tiles.

Making Mosaic Art with Penny U-Mixes

U-Mix assortments give artists the unique option to customize their color blend. Use penny tiles to create dotted patterns, curves, flower shapes, and round details. Arrange whole pennies or circular segments into swirls, waves and spirals.
