I was wondering if there is anyway I can make Etching Solution. If someone could tell me what the properties are. Or if anybody knows a cheap method or something. Any suggestions, please

Etching solution is nothing but Ferric Chloride (FeCl3) dissolved in water. This is easily available in Chemical Shop or hobby electronics store.

Alternatively, you can use ammonium persulphate, (NH4)2S2O8, in hot water.

For do-it-yourself solutions, search around Harry Lythall's site. He uses a mixture of hydorgen peroxide and hydrochloric acid. But your gotta be careful rolling your own. If you don't know the basic precautions of using acids, don't even try. Harry also has toner transfer methods using cheaper media than PNP Blue. His site is at http://w1.859.telia.com/~u85920178/
