Primitive Technology: 2.5 m Natural draft furnace experiment
AdultsEngineeringExperimentsTechnologyI built a 2.5 m tall furnace to see if it could get hot enough to smelt iron by natural draft alone. Such furnaces work by the stack effect where the tall furnace causes negative pressure inducing an air flow from the base of the furnace and out the top.
Primitive Technology: Charcoal retort experiment
AdultsExperimentsTechnologyI tested a charcoal retort based on the Hookway retort method using only primitive materials.
People said this experiment was impossible, so I tried it
AdultsEducationScienceExperimentsA massive thank you to everyone at Goldschmidt for making this possible. With special thanks to Dr. Axel Hoeschen, Christof Gassmann and Claudia Koch.
