Here was my process to build the dye oven (dye oven planning post can be found here):
-Stand the pot over the fire area. I used bricks and metal rods to build my stand, the same setup I had for dyeing over an open fire.
-Put the dye vat on its stand and start building a brick igloo around it.

-MORE BRICKS

-Cover the holes in the brick structure as best you can with a mixture of clay, water, and straw/grass/etc.

-Put a door in place (I have a metal trough as a door)

Now set a fire under your pot and dye stuff!
