Thanks Chris! I have not been as meticulous as I should be apparently. Good info Chris thanks
What are your thoughts about grinding off counter enamel from silver to expose the silver. It seems to me a waste of silver to keep it covered with counter enamel after the piece is finished

I have two issues that I would like input on how to solve, please:

1. After etching copper I use clear flux to seal the copper and so I can add transparent enamels - however, it turns black and ruins my etching. I've tried burning it hotter and longer to no avail. I'm using a Japanese lead based enamel but I've also tried lead based from Thompson and still no luck.

2. I understand the rational for counter enameling a piece - but it seems a waste of silver. Do you grind the silver off the back after enameling? It seems customers would prefer to have a nice silver back rather than enameled. Thoughts?
