Only Copper
November 1st, 2008 WendyLee Posted in Etching Metal, Techniques | No Comments »
Using the Saltwater and D cell battery to etch you can use other metals then just Copper.
I experimented with the following metals and worked successfully.
*Copper
*Brass (does appear to take longer, the brass I was using was print making quality brass but the definition was far better then the copper)
*Nickel Silver Looks like sterling silver when polished but does not have the price tag attached to it and iis easily ethed in solutions that you cannot etch Sterling silve rin.
*Gilding Metal As this is a brass based alloy it had the same effect as etching brass and took just as long!
* Shibuichi I have a piece currently in the solution now of Shibuichi. It will be interesting to see how successful this is. The shibuichi I am using is 25%. So I don’t knwo how the 25% of silver with affect the etching process if it does at all. Will let you all know How I go with some photos!
