Does anyone have any advice on removing overfired enamel from the areas that I can't reach with a file on an intricate fine silver piece? It's a pendant in the shape of a cherry blossom branch with lots of little flowers that were enamelled for a little too long - it was one of my first attempts at enamelling, and whilst I'm still no better at it I thought I should try and salvage this little piece.

(Sorry if it has been asked before, I did a search but the results were all over the place!)

Thank you!
