Can anyone help with a mixing procedure for the 100% Potassium Carbonate solution used in part B of Sandy King's Pyrocat-HD formula posted on the Unblinking Eye site. I have been trying to mix 100 grams of Potassium Carbonate into 100ml of distilled water for over an hour now and I can not get the majority of the chemical to stay in solution. As soon as I stop stirring, most of the powder just settles to the bottom of the beaker.
I am new to mixing my own chemeistry from scratch and am going to verify that my measurment was correct (a digital scale indicated I had reached 100grams after about 3.5 tablespoons were added). Mixing was done at room tempeture(70degrees).
Any help would be greatly appreciated.
