First Frost

          This morning I awoke to a light frost. Something I was glad of as I have been wondering how well my fine little house will hold heat. Both fires had gone out during the night and yet it was still 17 degrees inside, and 0 degrees without. The chimney appears to hold a lot of heat for some reasonable time. Good old fashioned thermal mass principals here. I have also observed that the chimney has been built of a stone that looks like it could have come from the local iron ore mines, black and with shiny glass like areas. I shall look into this further as maybe this material is as good as soapstone.
