I recently decided to try building a simple charcoal forge in my backyard based on the one in this video https://youtu.be/Fuk7Lw_uV5s. I've got some bricks that I plan to coat with a refractory cement and an old hairdryer for air. My question is where to put the forge itself.
My two main options are a firepit we have on the concrete patio (just a circle of stones, about 2 foot diameter, filled in with the ashes and such of past wood fires), and a dirt patch nearby (~4x8 foot rectangle surrounded by concrete and full of some kind of moss and tiny sprout plants).
Is there some advantage or disadvantage to either? I'm leaning toward the firepit.
I have pictures of both on my phone but i'm not sure how to include them
