- Demonstration using glass plates and powdered grits to polish rock chips and cut-off thin-sections, as well as the important final hand grinding stage and inspection under the microscope to determine when the final thickness of 30 microns has been achieved.
Thank you for a wonderful, enjoyable and informative series.
An excellent presentation!

great presentation appretiate it
what type of microscope and model do you have?
What is the best microscope if I don't have a thin slice of rock as a sample? I mean what if my samples are just small raw rocks?
Any low power binocular microscope will be suitable, around 20-60x magnification, with a good light source. Tiny crystals are fascinating under the scope.

Would you rather except some rock fragments and to prepare thin sections for me please? Actually I’m working with some meteorites and I need thin sections but I have not the equipment. I can pay you if can reply to me for each. Thanks
Curious to know what material the grits are
Usually it is silica carbide. I would suspect he is using silica carbide in this video. That is the cheapest. Others include aluminum-oxide and diamonds (either polycrystaline or not). A polycrystaline diamond grit provides the best cutting action and will last the longest.
any job of thin section making petrographic study.
What are those numbers 60-90 grit
Size range of the grit particles.
Hello, can you send me a meteorite for classification?
