Smalti Mosaic Glass

SKU: smalti-mosaic-glass Category:


Smalti is traditional hand-cut mosaic glass that has a different look and feel from molded tile. It is the glass to use for reproducing religious icons, antique mosaic art, or making modern interpretations of classical designs. Is is sold by the 1/4 pound, which is 40+ pieces on average.

Mud Turtle Mosaic™ brand smalti is a next-generation smalti. It looks like ordinary smalti (non-molded hand-cut rectangles), but it can be cut more predictably and cleanly with less waste and fewer shards, which often an issue with smalti. Avoid having to discard a significant percentage of your expensive materials as cutting scrap. This brand cuts more efficiently because of how it is poured and cooled. With Mud Turtle Mosaic™ smalti, extra care is taken to ensure that the mixture is more homogeneous and that little or no cold seams are formed during the pouring of the molten material out on the slab. The result is that are fewer blobs and swirls and fault plains inside the glass. These artificial internal structures are what causes regular smalti to break in such odd ways and form such vicious finger-poking shards. With this brand, there are also fewer surface pits and crevices for grouts and mortars to contaminate.

Product Coverage

One sales unit (1/4-pound) covers a little over 9 square inches uncut with no grout spacing. Depending on how you cut the smalti, you could get about 12 to 14 square inches of coverage per 1/4 pound. A good rule of thumb is 2.5 to 3 pounds per square foot.

Traditionally mosaics made from smalti were not grouted. However, if your mosaic will be outdoors or in a wet location, then you need to leave a gap between the tiles so that if can be filled with grout to seal out moisture. Having a grout gap means that you will need about 10 to 15% less smalti than otherwise.

Piece Count

One sales unit (1/4-pound) USUALLY contains 40+ pieces, with 42 being the average for the material we sampled. However, the smalti is sold by weight, and if the factory cuts a batch with slightly larger pieces, then that batch will have fewer pieces per 1/4 pound.


Smalti is hand cut when it is made at the factory, and so it had a different look and feel from regular molded glass mosaic tile that is pressed into a uniform shape. Smalti is also significantly thicker than most of the glass tile we sell. For these reasons, mosaics look best when they are made from one type material or the other but not both.

Cutting Smalti

Mud Turtle Mosaic™ Smalti cuts extremely well with the mosaic glass cutters that we sell.

Use in Mosaic Art

This smalti is probably the best you can find is you need to render small details in smalti because it can be cut smaller with less waste than other brands. It also has little or no surface pitting, so you can grout a mosaic made from this material without having specks of grout remaining all over the face of the mosaic in pits. The product is highly recommended.
