Primitive technology with survival skills: Experiment with limestone kiln (CaO)

In this video we put the furnace to burn calcareous lime (CaO). We used primitive technology to build a kiln and take limestone from the mountain. With survival skills we got the fire and calcined limestone for 8 hours at a temperature of 900. Then we obtained lime. Lime (CaO) is used in industry and construction. We will continue to make videos of original technology and survival skills. Subscribe to the channel to watch the latest video. Thank you.
