Over Firing Enamels = Muddy Enamels

 

Patsy – Wow I hadn’t seen your web site before. Very impressive. I’ve been meaning to let you know about my experiments with the customers enamel, that complained of a blotchy, muddy areas in her transparent enamel. She thought the fine silver was contaminated. I did a test with her enamel and my enamel and her metal and my metal. I fired everything 5 times at 1400 degrees and there was no discoloration. My conclusion is that temperature makes a big difference on silver! Keep on ‘ on!

Coral,

Thanks for the note, and sharing your testing. Yes, you are right! So many do not understand that vitreous enamels are reactive on many metals. Testing is important and you have two choices, learn the fluxes that are available to us and second, keep the temperature down! *)
