> For _small_ quantities, specially buying a microwave seems a bit OTT.

There is no way I'll be 'cooking' FeCl in anything that will ever see food
again. So a dedicted microwave would be the only way to heat etchant in
small quantities.

The other item that has become pretty obvious that in my environment doing
board in the kitchen sink just doesn't work too well. No matter how
careful, there is always the possibility that something spills. I'd rather
not have any poison near my food preparing areas, period.

Looking at building an etch tank, from a cost perspective it is equal to
getting a small microwave. Having etched board in a ammonium persulfate
bubble bath many moons ago, I know it does work well. I never tried the
sponge method yet, but read it is supposed to be excellent. Problem is, I
don't have the confidence to play with FeCl in my stainless steel kitchen
sink...
