Question with mosaics

shasta_2008July 27, 2008

I'm usually on the garden site but decided to look at some projects while having some coffee. All of the mosaic pieces here are fabulous! I have alot of scrap glass I would like to use up and would like to know when making glass mosaics do you have to grind the edges?

Shasta, some of the gals here do grind all their glass, I don't I use it as it breaks.

I grind occassionally, depending on whether or not the edges and points cause concern for snagging someone's skin. I do tumble alot of pieces, but also smooth snags with my dremel or very fine wet/dry sandpaper. Just depends on how rough it feels before I grout.

Hi and welcome! I tumble all my stained glass tesserae for about an hour to smooth the sharp edges. From what I have read, the sharp edges aren't supposed to be a problem because the grout should come all the way up to the top edge but in real life, I have seen many mosaics that have dangerously sharp edges. I also have a carborundum stone (kitchen sharpener) that I sometimes use to get rid of a point.

I tumble when I can, and grind when I must. Grout just doesn't seem to come up high enough to protect hands from
the edges. I grout with my hands.. so it is a must for me
to have the edges smooth. Grinders run about $100, and a tumble about $30. Well worth it in my eyes/hands!lol!
