[Cob] frozen cobphil phawn1 at excite.comTue Dec 28 06:16:38 CST 2004
It has been several months since any cob was made at this site. It should be thoroughly dry now. The mortar depth was no more than three inches. To answer Joe's question, if you cob in freezing temps, especially here in the mountains, your cob will 1) not dry until the temp rises well above freezing 2) expand as it freezes and then turn to mush when it thaws. The cob mortar in question here was dry, got really wet on its surface and then froze. I don't know the full extent of the damage yet. I will be going out to look at it this afternoon. More when I return.
