Kendal, You can get ferric chloride from Radio Shack. It is used for circiut board etching, but works well for pattern welded steels. You don't etch untill the part is fully polished. There has recently been discussion at anvilfire.com Guru's den, that forum doesn't have threads, just read the last few days posts. There are some books suggested that are well worth reading.
what is exactly you want to do?,Do you speak Spanish?
