Is sandstone good to be used as the oven floor?

[Barry R]

Hi, I am in the Uk and are in the process of building an oven in my garden and am thinking of using sandstone as the oven floor, is this a good idea? Also I am not keen of having a chimney but instead having a vent at the front of the oven , will this work as well as a chimney?

Thank you

sandstone won't take the heat, so I think the answer to that is no.
the chimney is right on top of the vent at the front of the oven - so not sure what you mean by the second question. You need some height to it to get a good draw out of the oven. Unless you are thinking of just having the smoke come out of the front of the oven with no vent. In which case, you may not keep your eyebrows.

No, sandstone is unsuitable for an oven floor. The vent needs to be outside the oven proper, that is to say it should be baffled by the 63% of the door VS dome height.
