@gitnitdun thank you, we had fun doing the video. Even though we did not get anything we could measure the letharg had bigger beads of gold. Plus, we used a lot less propane cupelling letharg.
@ErnieDionne the letharge cupelling about 15 to 20 min. The lead cupelling was 20 and 45 minutes. So cost saved in propane alone would make me want to use letharg. We are going to do a test on the pyrite to see it with different ore. Stay tuned.

Very nice Michael, great job. What was the difference in cupeling time between the litharge and the lead?

@@mt.treasures911 That’s exactly what happened to both of mine. The process is consistent.
