I spent the weekend in my place during one of these cold spells. It got in the negative temperature range and one night it apparently felt like -23. It was a nice chance to see how all this work held up to such conditions and also find all the leaky spots!
It held up great! Obviously waking up in the morning to cold as I had to restoke the fire was inevitable. Some of the areas of base coat plaster that had leaks from outside air developed frost around them making identification very easy! I’ve spent my time putting finishing touches to the first layer of plaster inside and am now gearing up for the top coat. I’ll be doing three different versions in different spaces. A sifted sand, fine wood shavings and cattail fluff. All mixed with the same clay I have been using. I’ve done test batches of all three and I’ve been happy with how they have turned out. I also now have my kitchen area set up inside the with the sink draining to the outside. I’m also very pleased with the cooking abilities this stove has. I don’t even have to remove the circular pieces to get a good boil going or fry some veggies.
