I tumble glass all the time. I started tumbling scrap pieces of
stained glass to make ‘beach glass’. I made Cone Tops out of stained
glass, then hung the pieces of beach glass from them to make wind
chimes. They are beautiful, even if I do say so myself. When the
wind blows, I race for the phone……
I then started cutting up old wine bottles, 7-Up bottles, blue Vodka
bottles, …into circles and tumbling them too.
I use a small diamond bit and drill holes in the tops, use fishing
line to hang the glass , and decorate the fishing line with the glass
beads that I make and don’t like , to add color.
My tumbler, from Covington, has a rubber barrel and still dosent
show any wear. For tumbling media, I throw in the glass, a handful of
pea gravel, a handful of sand, and a cup of 600 grit Powder. In
about a day, (check daily), the glass is frosted and has smooth
If you just want smooth edges, without the frosted look, Arrow
Springs sells a stone for this purpose. Rub it lightly on the edge
of a piece of glass , and it will no longer cut you. I do this for
table top waterfalls, where the water cascades over pieces of broken
glass. I want smooth edges but shiny surfaces to reflect light.
