Interesting for sure man I process icewax but I have never vac purged it does it retain full melt in that form?Correct... ice water hash > pressed patty > vac purged at 85degrees for 1 hour.
H2O boils away under full vacuum. Called a cold boil. You also have to add a desiccant to your vac oven for this to work properly. Calcium Chloride works best.
