This gives an excellent stain, as good or better than even the best warangan from Solo of the past, it is fast and totally predictable. However, in most countries any poison requires certification to enable purchase.

Sorry Alan, when i said "industrial" i was thinking of lab quality white arsenic. I actually didn't realize there is a separate kind of arsenic like you describe. The white lab quality stuff is the stuff i have used.
