I have heard that now days in Jaw also Selenium is used. Because of shortage/price of arsenic. Anny one ever hear about it? If it works must be one of it oxides. Haven't figured it out witch one. Sugestions, please?
And about the arsenic. Like Alan said, Di Arsenic tri Oxide (As2O3) works best, since it is the most agresive...lethal too. 100mg in your body will kill you, when taken oraly, dont know about in to blood stream.. probaly much lower.
than you have Realgar, red to orange AsS, easly bought in mineral shops. The mor red the beter, is what people say.. i got a big chump here of maybe 300Gr red to orange colour.. it works. Just when you make the bath ready.. pulverise the realgar realy good, i use a farmacy mortar to grind. A big hammer does the job too
. and piut the stuff in lime juice. I never put it on a filter.. let the fiber rot.. good for the acid value (PH). En my best tip.. let it stand for atleast a year... other wise it wont work properly... limjuce i white/yellowisch... i should become dark red to black sollution... you will know when you see it when its ready.
The pinkisch mineral, i have seen it. But never used it my self.. And dont know if its a mixture of compounds, or a seperate mineral, cant find anny info about it.
And finaly orpigment a other arsenic mineral yellow colour! As2S3. Never used it my self.. but hear diffent story's about it. The person that learned me.. never want to have it.. since it's not working...other people say otherwise..

Ps sterling arsenic is metal arsenic, of non use for us! just looks pretty for mineral collectors. But it wont react. You can make trioxide of it.. but it dangerous.. so i wont tell you more about this
