[sdiy] Microwave Ferric Chloride

[Ken MacBeth]

Hi Steve, It took me a while to work out the best way to go about keeping the ferric chloride hot- sure the microvave occurred to me, but I guess once you've heated it up, it will cool down...when it's cool again, which happens quickly, you are back at square one. I did exeriments with baking trays, you know, the kind used for cakes, pastries etc... I would put the board to be etched and liquid ferric chloride into the baking tray and heat over a small heat on a gas cooker...sadly, the baking trays eventually etched too, so cooker, clothes etc. got in a bit of a mess. I realised that I wanted something like an old darkroom enamel dev. dish, but they are very hard to find. At a local breakers yard, I came across a grilling tray from an old gas cooker, it's enameled, serves very well and in the pic you see me adding neat ferric chloride to heating water- an A4 size board takes on ave about five mins, and thatt's double sided too!...point to note, this is done from my rented fl!
 at, I
 lost wife+house because of previous mess, lease note.
Best to you, on this sunny Scottish morning, Ken
