During year of (2009-2011) I gathered different parts of lead (mostly wheel weights) and friends giving lead parts. I made a "male" mold from white Styrofoam immersed in silica + 3% of betonite (should have used up to 10%). Heating/melting took over 7hrs - propane 250K BTU heater and 40K BTU hand held heater. Rented 250K BTU propane burner: https://www.loutec.com/location-equipements/chauffage-gaz-naturel-huile-propane/chaufferette-radiante-0-a-250000-btuh-1450218610 Rented 40K BTU propane hand held burner: https://www.loutec.com/location-equipements/chauffage-gaz-naturel-huile-propane/lance-flammes-feu-ouvert-400000-btuh-1098015018/
