Hi everyone
I've not been around for a while and the jewellery has had to take a bit of a back seat. Anwyay - now back on track and I have some questions re Keum Boo. Apologies if this has been covered elsewhere
I am going to silversmithing classes (which is working out great) but the tutor has no experience of working with Keum Boo and so its a case of the blind leadling the blind... I had a go with the technique this week and I definitely need some more practice. The gold came away from the silver when it was in the tumbler.. so I guess that it hasnt had enough heat or pressure.
I was using a hot plate with a piece of copper underneath the silver to allow even heat distribution - as had been recommended. How long approx would a 1mm piece of silver need to heat on the hot plate before it can be burnished.
The gold foil was placed onto the silver before it was put onto the hot plate - is it OK to do this.
My piece had been hammered and repeatedly heated (3 times) and pickled as per instructions. My tutor advised that there was no need to polish the piece after it had been in the pickle before applying the gold foil but I am wondering if it would be better to polish first and add gold at final stages.
Any help anyone can give is much appreciated as I am wanting to have another shot next week. I am making a series of pendants based on the golden ratio principle, which are partly textured. Eventually I want to apply the gold foil to part of the textured surface. Sorry for the long message!!
