[QUOTE="Car 54, post: 348163, member: 85"] I can't remember what high Pd alloy I used for a short while, gave off a charcoal gray oxide that needed to be blasted off. Terrible stuff, as I would get bubbles through the 2nd opaque firing. Some of those would continue to grow oxides through the proceeding firings. The posted image looks like a green caterpillar. Good luck in not having that affect the shade without heavy opaque masking ;) :) [/QUOTE]
