staining boro

[Brian Newman]

I know there are ways of staining boro that involve kilning in a chemical bath (red or amber). Has anyone ever heard of this mixed with a binder and painted with?

[Matt Hess]

I have heard of people using tea to stain white boro.

Hanovia lusters are available through Glass Craft, and come in a wide variety of colors. You paint them on when your piece is cold, and fire them in the kiln at 1000 degrees. Be sure to have proper ventilation- the stuff stinks, and is very dangerous to breathe in. I use vinyl gloves when I work with it.

Lustre is't the same as stain, is it?

actually glass stain is a lacquer base stain that is brushed on after the piece is finished, there use to be many colors available. I used this stuff 25 years ago, the draw back is that lacquer base stains evaporate over time and lighten up in sunlight, so I quit using these years ago, they use to use this for spun glass alot.

The lusters Wonka talked about, I use. These are put on like he said, but they don't rub off or wash off if properly applied and at the temp it says.

have fun with that crap. It has a limited amount of workability before it hazes. Not too sure you would call the ion exchange proccess staining but who knows.

[Brian Newman]

They have a fancy name for an old technique. If this type of finish could be painted on...
I know I have seen directions for this as a liquid bath, both red and amber, but never as a paste.
I will try to find the directions in my tomato box of scientific journals and post them. This technique is used for making glass for photography chemicals.

I think Kimble has a lot of this style info in there scientific catalog . I think they even have info on what will etch boro.
