We argued that there needs to be a liquid lead layer covering the bottom of the pot to improve conduction. Uku took out his 1,5 kW butane burner and went to the rescue. Indeed, it helped melt the lead, accelerated the process, and a pool was formed. But the process was asymptotic – after removing the torch and adding lead. The pool froze, only a small part of it remained liquid in the center of the pot, where the heat flux was greatest (edges of the pot were cooled by air). All this, meaning, all this nothingness had taken us an hour. Bad news – we needed more power.
