Sorry can't help about the official ones...but the little mini-crock is still working well after a decade and the price was right. I, too, would like to hear from someone using something a professional version. knave -- used for cleaning metal after soldering  |

rockpickerforever thank you! @rocks2dust, wpotterw, rockjunquie, and hummingbirdstones thank you for the identification. Neither chrysoprase or gem silica seemed right and I hadn't heard of Andean blue opal, although we did recognize the opalization. Streak test confirms opal. Thanks!!

These pieces are from an Arizona estate. Material is hard, at least a Moh's 6. What do you guys think?

Also recommend the oil sucker to make the job a little quicker and a little less messy. |

Sorry carver but I know next to nothing about meteorites. We are cutting copper ore with native copper, silver ore, and banded iron. The banded iron in particular was high wear on both the economy blade and the 303 blade. |

carver we bought the "for metallics" blade in 2018 from Johnson Brothers, their part number was M10-15-58. Recommend slowest feed rate and pay attention to the temperature of the blade. We have cut some pieces of rough that were near the size limit for the ten inch saw and the temperature issue was apparent. Frequently our saws run for hours, cut after cut, but with the large metallics the blade will get very hot after about three cuts. We opt to make one cut, give cool time, then cut again. This blade produces smoother and cleaner cuts on metal ores with much longer blade life.

Yes, we are using vise and auto-feed...and oil in 10" saw.
Also occasionally use a 10" blade with 0.015" kerf for cutting metallics. The blade was purported to be for meteorites but it works nicely for native copper, silver ore, and banded iron.
We use a 6" saw with water for hand trimming.
