Drying by boiling in subfreezing weather

Nov 04, 2007 3 Replies

I am thinking about trying the boiling method to dry rough turned work. Steve Russel recommends a three day initial drying in a pile, under a tarp. How can this initial very wet phase be accomplished in areas where temperatures will be below freezing for two or three months?



TIA Michael


One answer is "sublimation". Water that is frozen goes directly from a solid to a gas. I don't suppose drying would be as fast as having your tarp out in the Arizona desert sun, but----.

Might want to check on the conditions necessary to sublimate water. Not likely to meet with them unless you're in Omyakon or Vostok station or are creating a high vacuum as well.

Since the water loss that counts is the water bound to the cellulose by hydrogen bonding, lowering the temperature at atmospheric pressure would make it much less likely to have the energy to escape the influence. As a regular turner of "frozen" wood, I can tell you that when it thaws, it flows!
