Melting black iron sand from Piha beach, in prototype arc furnace with galvanised nail rods.<br />It is interesting to see that with this iron sand the conductivity is not super.<br />With an insulation tester the reading across the electrodes is 500 k.ohms.<br />To trigger the process some Sunlight dishwasher liquid was used.<br />It surprised me how well the plastic container stood up to the job, although the plastic became very hot and soft and caught fire later on.
