Plasticity of wood

Q: We are in a discussion about the role that water and moisture plays in bending wood. I know that how well a piece bends is dependent on the moisture content of the wood but what role does the moisture play in the plasticity of the sample? If you were to take a piece of wood that is oven dry and we're able to cool it in a chamber with 0 percent RH, would application of heat alone be enough to bend the piece and maintain it's shape?

Table returned

Q: We have had a large dining table returned to us this winter after four years of use. It had a glass top. What happened is that the table crowned - the top warped with the center being higher than the edges. The glass cracked too. Even though it is four years old, we will probably replace it in the interest of good "public relations." Can you tell us what has happened?

Q: Can you suggest a good wood for a sauna? Cedar is too expensive, redwood is out because of environmental concerns; and pine has too much resin that bleeds out? Perhaps spruce?
