Any difference between boiling and steaming?
Justin Snyder:
UMMMMMM NO, I mean no thank you. Justin
Gordon:
I believe that you can apply more heat to the wood by using steam. That's because boiling water (or any liquid for that matter) cannot get hotter than its boiling point. To change the state of water from liquid to steam, however, requires substantial additional energy. This is called the latent heat of vaporization. When steam condenses the additional calories are transfered to the wood as heat.
Justin Snyder:
I believe you are right Gordon. In fact, I know you are. If it were colder than the water, it would be water. ;D If you put it all in the container, the hottest part of any liquid goes to the top. (With the exception of frozen water. When it gets below 4*C it begins to rise again.) This includes the steam. If you put the tin foil on top like RyanO it holds the heat in and the area above the liquid water is hotter. The reason I have had better luck with steam, is because you can heat a smaller amount of water to a high temperature faster. Then the steam fills a larger container than the water did, making it easier to immerse the bow in the heat. Justin
Hillbilly:
Having tried both, I greatly prefer steam. I usually use a setup consisting of a coffee can on a Coleman stove. I lay the limb across the can and seal it off with aluminum foil. 30-45 minutes of this will usually temporarily turn about any wood to rubber.

Justin, what does "C" mean? :) No habla Celsius. This is the land of Fahrenheit, dude. ;D

This is an international community now. That was for our friends north of the border and the others across the pond. For your benefit, that is 39.2*F.. Justin
