Hello,
This is my first post. I tried using the search function to see if my question has already been discussed to no avail.
I am in the process of making my first
rocket mass heater for my greenhouse.
Here is my question:
I came across from free bricks that were used in a bread
oven. They have a ceramic glaze on on side. Does anyone have any thoughts on using them inside the heater core and heat riser?
