Hi guys thanks for the replys and the pictures ......i have posted some pictures or realgar[arsenic sulfide]the red one ...and orpiment[arsenic trisulfide]the yellow,both of these are easily obtainable[ebay]
.What i realy wanted to know was if anyone had tried to use either of these ores in place of the waranga[witch visualy seems to be a diffrent type of arsenic ore][does anyone know the mineral name for waranga?].I was thinking that technicaly either of these should work in the same way and that someone must have tried it.
