Re: Milling Glass

Hi Mariano,
I had a kit years ago that used contact paper
or you could use wax to layout a design on the glass. I think
the acid was hydrofloric, not sure on spelling. Comes in
a plastic bottle! I was very surprised to see something eat
glass. A mind blowing experence. I used to setup machines
that made electron tubes and mercury switches. We used the
acid to clean the switches up after the sealing operation. We
mixed Hydofloric-Hydrocloric and I think I remember arsenic.
The company where I worked is a toxic waste site. Ahhh the
memories.
