Once again, I’m harvesting an email question to provide material for this blog.
A muller is a tool, generally made from glass, used to grind paint (and sometimes pigments). The surface of the muller (and the slab it’s used to grind on, if that is glass) gets ground smooth over time. So it needs to be re-frosted.
I have a glass muller in which I grind my own pigments. Lately it has become quite dull so I started to research information on reconditioning the muller. I found that carorundum (silicon carbide or skateboard paper) is supposed to bring it back to life. I used sand paper but I have no idea where to get corborundum from…
can you give me any alternatives?
I use carborundum powder, which I got from Sinopia. Use your muller to grind a small amount in water and it will re-frost the glass.
