2014 – a flipping year

We rented the gas and the burner from a local tool-renting company. 11 kg of industrial gas and the burner. On the picture is the gas container after we finished pouring the lead. We do not have snow on the ground in Estonia, but that evening it was on the gas container. Thermodynamics in action – the gas expands and chills the container. We calculated that we needed roughly 3 kg of butane to melt all the lead we had. We definitely used more. This was due to losses. Smelting lead outside with near freezing temperatures has its drawbacks. Not enough though to keep the 50-60 kW burner at bay.
