Does the strength of gravity on a planet limit a species ability to create temperatures high enough to melt metals?
I read that at low gravity fire burns at cooler temperatures and reduced convection leads to reduced inflow of oxygen but I believe most of this is based on how fire behaves in microgravity. If true this makes me wonder if species on low gravity planets could advance to bronze or iron age level, being able to create high enough temperatures to melt metals? assuming their atmosphere has a similar amount of oxygen as our planet.
If there is a limitation to how low the gravity can be to create the high temperatures does that mean that high gravity planets will be able to achieve high temperatures much easier?
