Using Copper Sulfate Crystals


Recommended Posts

I use copper sulphate crystals

in a diluted solution in foil saggar firings. I mix very small amounts... 25 grams to a quarter cup of water and keep using until it is depleted. I use goggles and a vapor mask and nitrile gloves.I have noticed the wire mesh on my raku kilns is rusting... Possibly from the chemicals. I do fire frequently and thr kiln is 9 years old.
