Kaleidoscope Mini Vitreous Glass Mosaic Tiles 3/8-Inch

sheet of 81 vitreous glass tiles 3/8 inch temporarily mounted on paper

SKU: kaleidoscope-mini-vitreous-glass-mosaic-tiles Category:


Mini Vitreous Glass Mosaic Tiles 3/8-Inch by Kaleidoscope are sold temporarily face-mounted on removable paper sheets. These are the same thickness (~1/8 inch) as the other vitreous tiles we sell, and they are the same size as the other brand of 3/8-inch minis we sell, and so they can be used in the same mosaic. The color names are the same as the larger Kaleidoscope, but you should not assume that they will match these exactly due to batch variations at the factory. These tiles are hard and durable enough for use in outdoor mosaics. Price is per sheet of 81 tiles.

One sheet of 81 tiles will cover approximately 1/10 square feet assuming a standard grout gap of approximately 1/32 inch. To cover 1 square foot with the standard grout gap for this size, 796 tiles are needed. Most Mosaic Mounting Paper is 1.15 square feet and requires 841 tiles (29 tiles x 29 tiles). Use our tile estimator to calculate how much you need for your project.


Tile thickness is 1/8 inch nominal, the same as most of the glass mosaic tile we sell, which means that these can be used with other types and brands. Never assume that colors of different sizes will match exactly even if they have the same name because they often come from different manufacturer batches.

Cutting Tile

The Mosaic Glass Cutter is recommended for cutting all types of glass mosaic tile including these. Note that there is a limit to how small they can be cut because the sides of the tiles are tapered, and small pieces tend to fall over. We cut halves and quarters and diagonal triangles but do not try to go small than that, at least most of the time. If you are making the fine details of your image and need to cut smaller, you can lean pieces against each other, but that can get tedious.

Mounting Mini Kaleidoscope Tiles

For dry indoor mosaics, stained glass can be mounted using Weldbond adhesive, but thinset mortar should be used for outdoor and wet mosaics.

Use in Mosaic Art

These can be used in children’s crafts projects and stepping stones, but they are also used for photorealistic mosaic images and fine art. The advantage of this material is that you can use tiles from different manufacturers if you find you need additional colors.
