Right, I'm now thinking I'll tag as: building=bottle_kiln kiln=pottery disused:man_made=kiln former_product=pottery historic=kiln
and add tourism=museum where appropriate. Ideally I'd have the building as a way. Then the kiln as a node with the product. This allows the building to remain 'intact' while the kiln could go disused to abandoned depending on how bad it is. I note that the kiln requires more than the building, for example heat proofing, venting. Most of the bottle kilns in Stoke-on-Trent are stand-alone brick structures, and the whole building is the kiln. They were filled with pottery, the doorway was bricked up, and fires were lit at the bottom. However, this brings up a related point. Some bottle kilns are inside another building (eg the one at Moorcroft: https://www.flickr.com/photos/83551695@N00/4794476050/) How would I map those? I'm guessing I'd have two ways - one for the outer building, and one for the bottle kiln, with a relation to tie them together. If so, what type of relation should I use? Thanks for all the help and advice. Russ
