Awesome, thank you!
So as I understand it, I'll just need to keep an eye on the refractory and replace as needed? Is that something that I can just put another coat over or would I need to chip everything off and insert fresh insulation and recoat?
Regarding the table, we are building one with a couple of metal sawhorses and some square tubing. It will be outside in a covered bay next to the barn, so plenty of room to access it from either side. Love the idea of building a porch from fire brick. This is just a funny hobby so fast and simple is my thing too!
