This post is fumbling around because I am seeking advice and guidance on something from a very long time ago. I cannot do woodworking because of reaction to sawdust so I am looking to do copper work in the form of goblets, bowls and vessels. When in school many , many years ago I can remember doing this type of work in metalwork classes. I dare say this would be completely out of bounds today. I have tried looking for Videos , book etc but am struggling to find meaning full help. I think it the nature of the search words I am using. Can someone point me in the direction to get the information. I remember using hydrochloric acid, potassium chloride,brassing wire around the lip and base, and using a leather sand bag just to give an idea of where I am coming from. Thanks.
