I'm no Trapper -- in how many ways will we miss him? -- but I'll give it a stab. No cooking necessary. Use glass and distilled water. You'll be making about 4 ounces. The method is below. Just divide the numbers by 4 to match your quantity. (Half a kilo = 500 g. Divide by 4 = 125 g.) When you have a little bit of SSKI not mixed in, don't add more water. That way you'll know you have a saturated solution.
half a kilo. you might have a little bit left undissolved in the bottom, proof of saturation of the H2O. and yes, put the KI in first then add water to the 3/4 full level and shake, then add a little more water and shake and repeat till the KI all dissolves or the bottle is full.
