[Stoves] Uganda Turns to Local Volcanic Rocks As Substitute for Charcoal

[Bernhard Müller]

Teddy and stovers,
as I am in Uganda presently, I immediately took care for the matter: it is pumice. Most of us know the properties of pumice. The Ugandan pumice is of middle grey colour. Americans, who live in New Mexico, get the much better dark black pumice. 
Well, it was nothing but a sensation journalism, but I could imagine that it works well as an insulator.
