Hello Everyone, I am just a home owner DIY enthusiast. I am getting tiles installed at my home. We are using Gulf Stone Quartz Stardust Black Opal Tile (like this: http://www.crowntiles.co.uk/60x30-quartz-stardust-black-opal.html). I would like to cut small squares of this tile and use them as drink coasters. Could someone please let me know if I can polish the sides of these tiles so that they are shiny and smooth like the top? For bottoms, I plan to attach felt. Thank you.
