Galley Cooling Systems in the 18th century

[jud]

I would expect to see a copper pan about 1 foot larger than the stove footprint all around and about 2-3 inches deep filled with sand with the stove sitting on brick platforms at the corners with air clearance between the stove and sand. The sand could be changed as needed and also wetted to cool it, wet or dry it would block high heat from penetrating to the wood deck. A brick platform might also been used as a platform for the stove. Metal transfers heat, can provide a resistant platform, but without air circulation behind it or other heat shield, heat transfers quickly through it to the material it is resting on.

@jud I do agree with you. I add  just to all you wrote, my view for the upper part. As I wrote above my beieve is that the panel (basin) on the top deck (where the ducts sit in) had water in it and it was made from cooper or most possibly it was made with riveted cast iron plates.
