WOO i have got so much done over the last few days, all of my metal pieces are etched now... a few dramas along the way. I have never etched anywhere but at uni, but with the deadline coming up i had to brave it and try it at home. The Metal is Nickel and I'm using 70% Nitric Acid 1 part acid and 2 parts water (Its pretty strong so that the thin lines etch enough before any stop out starts to fall away) here are some pictures :)

Uni and my home in Cambridge have some differences, 1. At home i don't have a fumes cupboard! Just as i was setting up my etching outside the heavens opened and soaked everything in sight :( I ended up etching in my bathroom with the fan on and window open wide lol. 2. My house is very warm and Uni is pretty cold... now heat helps the acid work faster, maybe too fast in this case! I had to watch my metal like a hawk and on the first few pieces the stop out (liquid etching ground) started to come away and the metal had to be taken out early to repair the design, i added a little more water to help prevent this happening again. But any-who i learnt my lesson :P I'm going to miss that etching room at DMU more than i realized.
