Tweetok let me get this right, im thinking of doing the water test, first i get the water put it in a pan, put the thermometer in the water and let it heat up to about 100-110 degrees, then put the powder in the tube, and put it in the water,( im going to try to rig something up so it wont touch the bottom of the pan), then start putting a little more heat under the pan while watching the powder and the thermometer at the same time, then record when it starts to melt and when it completly melts. is this correct? thanks again
