Wayne, when i bought my arsenic it was $25 a gram, but the hazzardous material fee was almost as much as the arsenic itself. But using the method i use actually uses very little at a time, so i still have a bit left. You will probably get a good effect from potassium sulfide, but i doubt you will get the "correct" color for the particular iron of your blade. Given the keris you are experimenting on this might not be a big concern, but it would probably make a difference in a cultural context.
