Having rediscovered an old stash of enamel powders last week and having great results with the random blue one I picked out, I have done some samples with the others...somewhat less successfully!!
I know enamels do deteriorate with age and I haven't used these for years - so it might be that - but it seems to be the red, brown and purple colours that are just turning out yukky and I know reds can burn out if the temperature is too high.
I do have an enameling book upstairs - but it is so much more fun to get it from you...the hands on experts!
I fired the blue successfully at 800 this morning (I went for the middle of a range suggested by a website on enameling) ...should I go lower for the reds and purples?
Any insight on the firing of enamels for a relative beginner would be great!
