Looking at a job tomorrow.  These are, supposedly, glass tiles, but not super soft as you would assume. I am guessing that they are engineered glass tiles as the guy said they are molded.  Sounds a lot like engineered stone, substituting the glass for the quartz. Made in China.

 

There is a pattern, from the honing process, that they want removed or disguised.  I am packing up a bit of everything to do some tests.  Diamond pads, AO powders, steel-wool /acetone, gorilla/spinflex pads. 

 

Any ideas? Anyone ever work on this stuff before?
