Some years ago, in Italy i bought realgar in a mineral shop and after i used it on a keris blade. The result was bad: at the and of the process (in a solution of realgar's dust and lemon) over the keris' blade remained a very thin coating of yellow /orange dust (sulphur?) and was very difficult to remove this dust.
On the contrary pink realgar buyed in indonesia never leaves residual matter sticked on the blade .
