A friend of my parents gave them a whole box of pieces of glass for doing stained glass, and they don't want it, so I grabbed a few pieces and I am grinding them up in my rock tumbler to try an experiment for ceramics class.

The rock tumbler is pleasantly quiet when full of glass versus when it's full of rocks

@Stormgren I'm gonna try making glaze out of this. The grinding medium is silicon carbide, which is also an ingredient in some glazes (like crater glazes), so I want to see what happens if I fire the leftover sludge

@401matthall It's not this quiet when it's got rocks in it.

You can get this one at Harbor Freight, if you have one of those near you.

@JohnS_AZ that will be a side product!

@JohnS_AZ Even smaller than that. just glass sludge mixed with silicon carbide. I'll mix it with a flux and try using it as a glaze

@Stormgren Me too!

@stepheneb @JohnS_AZ Small amounts of it are used to help metal ions in the glaze reduce so that you get more vibrant colors out of some of them, like copper. I think the carbon in the SiC burns off as CO2 and the silicon joins the rest of it as silica.

In larger amounts, you end up with crate glazes, which are cool also

@ChuckMcManis This one is from Harbor Freight. I think I paid $60 for it.
