Hi everyone. I’m new to cloisonné enamelling and am having trouble with my base coat.
When I fire it in the kiln it comes out with a yellow tint in it which can stay that way right until the piece is finished.
I have tried the following fluxes, all of which are intended for use on silver:
-‘W.G.Ball Leadfree Transparent Enamel Clear Flux, 477 for copper and silver’ (Comes out very yellow on silver)
-Latham Enamel Normal Flux T200
-Latham Enamel Silver Flux T232
-WGBALL Transparent Enamel Powder – Hard Silver Flux (7266)
-Milton Bridge 8102 Silver Flux
I have a small Prometheus kiln and fire my enamels at about 710 degrees celsius (1310 F) for about 2 minutes until glossy.
I wash the enamel and apply it wet packed or sift it.
I posted this question on the Grains of Glass website and someone kindly suggested I try “Soyer 3 for silver”, and while this has fired beautifully clear, it is leaded, so I can’t use my unleaded enamels over it.
Ideally I’d get an unleaded flux for silver that doesn’t yellow, rather than switch over all my enamels to leaded.
Is there anything I’m doing wrong from the above?
