I'm having a very hard time firing pink colors when I do cloisonne pieces. The pinks often turn orange. I've used Ninomiya L94 (raspberry), G703A, N14, SL5, and a Thompson leaded color called Tea rose. I can get a pink initially but in the final firings required to fill the cells, the pink turns orange even if I fire a a low temperature (approximately 1300 degrees F). Any suggestions??

Sorry Jean, I have not gotten back to you - its been hectic over the holidays - I am going to ask a few more experts to get an answer for you - how many layers are you putting down? are you using clear flux underneath? are you using Fine Silver or Sterling Silver?

I use Soyer #3 or Ninomiya #3 clear flux, sometimes several layers to insulate the pinks from the silver base. It's done on fine silver. Just lately I've found that if I lay down all the other colors first and then fire the pinks, it works better as I'm minimizing the number of times I need to fire the pink. The G703A and SL5 work pretty well that way, but the other colors are still turning orange.

I don't know who your supplier is for the Japanese enamels - I am assuming its Coral Shaffer from Enamelwork Supply Co.
I would definitely call her - perhaps you have a bad batch? Sounds like you are doing all the right things.

I've talked to Coral, she suggested using the Ninomiya N4 finishing flux, which is less hard than the Soyer 518 that I was using. She also said that everyone has difficulties with the reds and pinks.
