re lead melting

try building a loose brick wall aruond it all to reflect the
radiated heatback ont the vessel. also get a air pump or compressor
to blow in extra air. I melt lead and copper with a wood fire in a
loose brick kiln and a steel pipe running in with my cheepo aiir
pumpfor blowing up air matresses . yuo cant get to close due to the
heatit puts outwhen the pump is on.
