Anyone know where cupric chloride can be purchased for use as an etchant? Quantities would be small - a liter or two at a time.
A friend of mine (retired technology teacher) uses this to etch stainless steel. He chose that material because in the past he used cupric chloride to etch circuit boards (solution could be refreshed w/HCl) and he is familiar with the material. It would seem that refreshing in the stainless application wouldn't work but I don't think that matters to him as the quantities he uses (etch logo on knife blade) are small.
Thanks.
