Stephen, It has been my experience that microwave use is ok if it is short burst
and not used to generate too much heat. that will be different for every user due
to all the factors involved; amount made, wattage of microwave.....
If you try it and it works, great. I haven't had the need to use it for myself as
I make a liquid ferric. I did however use a microwave recently to help get some
Artcraft ferric into solution. I have found, along with the testing that Jeffrey
was doing, that all powder ferric is not the same and some oxalic acid is required
to get it into solution at certain levels. Glad to hear that your sky specs are
gone.
And a thought that I had about those pesky specs..... Many use hairdryers to dry
there prints. Some of these might have small amounts of rust that get blown out on
to the paper. We love clean air too, air purification requires moving air as does
AC units to make some rooms comfortable. I wonder if some of these indoor air
currents are the source of small particle of rust from fans, blowers, grates,
ducts, etc.???
