[Ice Czar]

my plan is to build cells for in-lab calibration based on the best info I can glean off NIST and my new vaccum pump
going for a
melting point of mercury -38.8344°C
triple point of water 0.01°C
melting point of gallium 29.7646°C

fisher has some pretty "clean" metal available (99.9999%)

till I can get the sensors professionally calibrated
currently Ive been following old school NIST shaved ice proceedure
