Not all realgar is equal, so the quantity required depends on the realgar, as does the result.

Rice water should work, in itself, not because it has starch (which certainly has) but because it contains Arsenic. but i see other people in this thread have commented on the low amount of arsenic in rice. Last edited by milandro; 23rd May 2022 at 10:58 AM. |

Maybe the combination of sulfur and some arsenic is what does it, with sulfur acting like a kind of multiplier which allows for even small concentrations of arsenic to be effective. But this is a wild guess. If I have some time I'd be interested to try adding some sulfur in with some ineffective realgar I bought off the internet and see if it yields a better result compared to just realgar alone, using the brush stain method. |

this seems to be a possibility, along with light and temperature being the activator of the process.
There is a lot of empiricism involved in this and very little science. The person who washes my krises all of a sudden went through a phase when the warangan no longer responded en was ineffective. Now he says everything is back to normal. I don’t think he knows why. If rice water with minute amounts of arsenic combined to sulphur produces modest amounts of arsenic sulfide and these stain the blade even in modest amounts that may very well be the reason why the salt-sulphur method works |

Yeah, i noted Bob's question at the time, but don't really know anything about antimony trioxide. Apparently no one else does either as no one responded to his query.
As far as i can tell it has one great advantage over arsenic trioxide in that i believe it can be purchased by the average citizen, but the question of whether or not it works remains to be seen. It does seem to be much cheaper (and more available) than As2O3, so maybe someone here might want to do some experimentation. ![]() |

I have cleaned rusty and heavily patinated blades ( NOT krises!) with “ Renaissance Metal de-corroder”. On top of efficacy, there is no need to use gloves.
Cover the blade generously with the gel, using reasonably narrow brush, wrap in plastic ( I used Saran Wrap) leave for 24-48 hours, unwrap, wash the gel off under faucet, dry and Â…thatÂ’s all. Rust goes away, some patina stays. Then , if satisfied, oil. I use melted Renaissance wax: when semiliquid, it gets into all scratches and crevices. If not, I would guess needs repeating or polishing. I like mine with some patina ( kisses of time), so never had to go beyond the first step. |
