As a new hobbyist, I’m trying delft casting. I was successful with my first piece but last time I used too much silver (grains) for my butane torch (in cold weather), so it didn’t get hot enough and it didn’t pour properly. As I was heating for at least 15 mins, the silver now has a ‘lovely’ green and red hue and looks porous. Can I just remelt it? Should I pickle first? Or is it ruined?
Thanks for any advice. I’ve only just found this forum so I found what I’d done wrong but don’t have the knowledge to correct it.
