Peter you will see the site speed up over the next week, I have had someone working on it and it's in test as I type.
The finish is HMG (hot melt glue) this applied to the finished turned piece, this is then sprayed black and then copper gilt cream is applied for the effect. Just a note if you are doing this make sure that the finish on the wood is 100% because once sprayed it will show ever mark.
All the best and thank you for your comments
