Trying to enamel the concave surface of a slightly domed piece of 24
gauge Argentium 925. about 30 mm in diameter.
Enamelling ==> 1450 degrees F for 2 mins, enamel flows fine and
seems to be OK.
But when the Argentium totally cools to room temperature, the entire
piece of enamel pops off the surface of the Argentium - a perfect
mold of the concave domed surface!
Cleaned piece again, pickled, heated to 250 degrees F for 10 mins
(as someone recommended) to build up surface of germanium ==>same
result - enamel pops off the surface when piece reaches room
Would Argentium 970 work any better, or do I just go back to regular
Any suggestions most welcome.
