Succeeding homemade photoetch #6

When the plate is done, you can store the developper liquid in a bottle an dstore it in a cool poorly lit place and it can be used again. Then you put your FeCL3 in a plastic plate (NOT an aluminium plate otherwise the whole buisness might turn nasty) and put your brass in it. Now there is another heating buisness. To work reasonably fast, the FeCL3 should be kept at a 40°C temperature. here I have been using my glass sheet and put it under the sun, the temperature raised fast enough for the whole to be etched in few time. But then I wondered about winter time.. And there came my step brother who said '"duh, you just put a lightbulb close enough and it will work'" :) The stuff should be agitated too, so I think I will buy a small motor and will try with a few resistances to slow it enough for the stuff just being agitated without doing some waves or whatever. Then remind to put ome *bad clothes*, because if the FeCL3 touches your clothes they will turn brown!! And now, just enjoy the pics...
