Bottom brackets with an slightly under-powered torch! The hearth is just a little open-front-and-top box of vermiculite,this reflects the heat and creates a hot place (it was this one, except I put the blacket thing underneath: bottom-of-page(ish) http://www.cupalloys.co.uk/brazing-ancillaries/index.asp). It really helped keep the BB hot and silver flowing, even on chilly winter evenings. The plates are also very useful for brazing over/near a wooden/mdf fixture, when you really don't want to set fire to the fixture. Haven't really used it since using Oxy-Maxigas.

What were you doing that you needed an insulated hearth?
Sorry to derail the thread!
