Ben xyz Posted April 22 Report Share Posted April 22 Since I've learned here that Palladium will oxidize over time (due to its manganese content), I'm wondering if there's a way to stop it or slow it down with a sealer of some kind? Not sure if it's a result of exposure to oxygen or it's something inherent in the material itself; or perhaps a result from handling? I have a (decorative) plate trimmed with Palladium and would prefer it not to tarnish and darken over time. Also wondering if that happens with metallic lustres as well?

Callie Beller Diesel Posted April 23 Report Share Posted April 23 I don’t know about other lustres, but gold and white gold are made of those actual materials, and don’t tarnish. Some raku glazes that contain a lot of copper can be prone to reoxidizing over time. Usually folks will coat pieces like that with spray varnish or similar. I think it could work for Palladium.

PeterH Posted April 27 Report Share Posted April 27 Can you confirm that you are talking about Amoco Palladium Glaze PC-04? Which seems to give a mirror-like finish by local reduction of manganese. As Callie has said you might try the ways people try to preserve reduced raku glazes, including wax polishes. I don't know if palladium luster gives a mirror-like finish. However as I believe that palladium metal is now even more expensive than gold I doubt that it's option worth exploring. Quote Link to comment Share on other sites More sharing options...
