Still standing!

I took out the forms and centering, and it’s still holding together! Here’s what the aggregate looks like. Seems to be mostly crushed limestone, but some pieces are certainly rounder than others.

I’ve got the work area set up for cutting bricks. The hearth will be laid as stretchers in herringbone pattern, and the dome bricks will be cut into thirds. So, the floor will be about 2.25 inches thick, and the walls will be about 3 inches.

I also picked up four bags of Heat Stop 50 today, and took my daughter to the zoo to make up for the long trip in the car.
