cool, now i gotta buy some glycerin..:D

pardon my ignorance, but what does potassium permanganate have to do with knifemaking? i suspect that its used for etching..??

The only thing that I know that it is used for is turning antler and bone to a rustic color.That and Knifemakers have a hard time finding it.

Hope this information helps.

The label says"For use to regenerate manual iron removal filters"

Can also be used for staining woods. Check the Knutsack Skinner thread for picture of this.
 
ah, thanks, but i'm pretty sure that it's a purple substance..either
that or i'm getting my compounds mixed up.:)

It will turn just about anything and everything that is porous brown so use caution, especially around your "valuables." :rolleyes:
 
It is readily avaialble from chemical supply houses but you can expect a bit of suspicion as it is also a precursor chemical for illegal drug preparation. In the dry form it is listed as an oxidizer and shipping methods are limited.
 
Potassium permangate...

It's purple, but it ain't paint or dye!

It's a reactive oxidant. After it oxidizes something else, and is thus reduced it's no longer purple. Purple means that some permangate remains and the solution is still capable of oxidizing things. Final color will be whatever color the stuff it is applied to becomes when oxidized. Insoluble manganese products may remain in porous materials or they may even chemically bind to organic material like wood and contribute to final color. Some of these products are insoluble in water, and black, brown, or dark green colored. Think "chemical burning", maybe. In reality, the details can get quite complicated.
 
Hey, firkin,

What you do for a living? You in the chemistry field, too? I was in pharmaceutical research for a career's worth, 30 years i don't miss at all.

fitzo,

yeah, I'm a chemist, but an unemployed one at the moment, so I don't do much "living". Gotta change that, I do miss $$ and the fun equipment and instruments. But flakey start-up companies, and all the instruments turning into computerized idjit boxes I could do without. Also trying to keep mass-screening machines fed inumerable tiny bits of "novel" compounds gets old fast, at least for me.
