Alongside the Dragon Kiln reconstruction in the Shanghai Museum are two other kilns. This one is a Northern Chinese type known as a Mantou kiln. It is essentially a domed cross draught kiln with a simple firebox, a domed chamber and a broad chimney at the rear served by flues low in the party wall between it and the chamber. Here the firebox openings would have been built into the blocking of the door but otherwise the firebox is just like the Dragon kiln one with an open fuel area directly in context with the ware packed in saggers. The sagger type is typical. Each holds a single bowl sitting down in the sunken base of the sagger; the next one then sitting into it snugly.
I am not sure about the scale here but this would work fine as it is by the look of it.
