Brass Etching ??
Hi
I would like to try some Brass Etching .
Has any one used Press and Peel Blue from [link]http://www.techniks.com[/link]
is it any good ?
I know I can get all my needs from [link]http://www.jaycar.com.au[/link] here in OZ

That press and peel is interesting looking stuff. The challenge for me here is finding a source for ferric chloride. It's sure to exist but how a "private citizen" in Japan gets hold of chemical supplies, I'm not sure.

What kind of acid is "car battery acid?" I've seen that for sale in the hardware store. And hydrogen preoxyde should be easily available at the phramacy.

RE: Brass Etching ??
Battery acid is sulphuric acid, H2SO4.
HCl is basically turning the copper in the brass to a salt, copper chloride (CuCL), while the hydrogen peroxide acts almost like a catalyst.
So we have Cu (copper) reacting with HCl (hydrochloric acid) and hydrogen peroxyde (H2O2). This gives us molecular hydrogen (H + H -> H2), water (H2O) and copper chloride (CuCl).
It's been a while since college chemistry, but that should be it.
The chloride in the ferric chloride solution (a dissolved salt) is dissociated in Fe+ and Cl-, again, another donor of chloride, but not so reagent as HCl and with that nasty iron wanting to stick to everything, like clothes.

sells a Photo Etching System kit but doesn't export the chemical .[:@]
the MicroMark system uses a inkjet printer and the Press and Peel a laser printer .
Now not having a laser printer I may try the MicroMark system.

The MicroMark system is really too small to be practical for RC scale use. We need the ability to do larger sheets. In one of dcflyer's thread he shows the setup he uses.

I had a look at DCflyer's thread. Look very good .
I have just talked the wife into getting a Laser printer for Christmas
Hay I need a new printer in the work shop so will give the Press and Peel a try .
Now we just have to get DCflyer's to do a full "how to " on etching

RE: Brass Etching ??
it 's a very brief post on etching with some photos but not to much detail .
Yes he dos uses a old crockpot and air bubbles but no temperature setting were on the post .

gives some info on etching Alum but again not a lot of detail
