A common misconception is that it is steam that causes the wood to bend (or the water in it), when in reality it is the heat. Steam has always been used because the boiling temp of water is 212 degrees and the amount of heat needed to bend the wood is 200 degrees. The steam has always offered an easy way to have controled heat, so the wood doesn't burn, and the desired minimum temperature is achieved, but you then have to deal with the warpage. Good one, Dennis. Thanks for sharing this with us.
