Can ceramic tile be filed down?
When glazed tile is cut it has a rough, ragged unfinished edge. You can dress that unfinished edge by smoothing it with a ceramic tile file. This type of file has carbide grit cemented to it, the same as is used to tumble stone. A ceramic tile file is a handheld tool that anybody can use.
What is the difference between glazed tile and unglazed tile?
Glazed tiles are coated with a layer of enamel or liquid glass before going through the process of firing them at high temperature however unglazed tiles on the other hand need not have any additional coating and they are ready to use after being fired in a kiln.
Is unglazed tile slippery?
This is where the process stops for unglazed tiles, which feature a more natural, rustic look with a textured and matte finish. This protective coating makes the tiles somewhat slick, but also allows them to be printed with a wide variety of designs and colors using inkjet technology.

How can you tell good quality tiles?
Here’s how you can determine the quality of ceramic floor tiles by looking at the floor tile rating system. Tile slip ratings. Wet Pendulum Test (P-rating) Oil-wet ramp test (R-rating) Barefoot wet ramp test (A, B, and C-rating) Tile wear ratings (PEI rating) Shade variation (V-rating).
How do you judge tile quality?
While porcelain tile quality differs in some ways from ceramic, the PEI rating system is used for both types of tiles. Operating on a scale of 1‒5, the PEI rating begins with PEI I, the softest, and ends with PEI V, the hardest. PEI ratings are determined by measuring the tile enamel’s resistance to scratches.
