This is because traditionally in Indonesia "warangan" is used, which is a mineral containing high concentrations of arsenic. In lieu of that some on this forum use lab-grade arsenic trioxide which is inaccessible to most.
The mineral that is used to make warangan is realgar i believe. It is not difficult to get, though many specimens appear to be relatively expensive and since i have never used it i could not really guide anyone on which ones are the best to use. I have heard the the redder/pinker varieties are best, but i cannot confirm. Lab-grade arsenic trioxide is far superior to use because its strength is always exactly the same and if applied properly it it will give the most consistent results. However, as you have already said, it is hard to obtain unless you have the right licenses. I have seen some good staining results with other, easier to obtain substances, but do not have any personal experience with them.
