Check out what is used to provide the acid to control the pH in
swimming pools there. It will be either sulfuric acid or the dry
sodium bisulfate. Either of these will make your pickel. There
also should be battery acid available which is also sulfuric
acid. You may also find citric acid as a food type supply. All
these can work outfor you and you probably will find all otf
them!! Jesse
There is a wonderful book which is of much value to all metal
artists, metalsmiths, silversmiths, and goldsmiths alike: “Form
Emphasis for Metalsmiths” by Heikki Seppa published in1978, ISBN
0-87338-212-9 many of the principles involved can be applied to
any size or scale of item from very large sculptures to very
small adornments, a great reference book.
