I spent part of yesterday at an excellent cob workshop put on by Brina and Darin at their home in Stanwood. Along with four other participants, I learned much about cob. I also had the opportunity to compare notes with another rocket stove afficionado. It was definitely a red letter day.
My goal is attending the workshop was to acquire the knowledge/skill for mixing the cob I will need in the construction of our rocket mass heater. Mixing cob is pretty easy, but can quickly resemble hard work. Fortunately I won’t need a large volume, and my cob won’t contain straw.
