can you please explain the process of using methylene iodide. we close the diagram of the microscope to a small opening, then place the small container filled with methylene idodide on top then look through the scope, correct? can you make a video of that? thanks

Hi, i' m wondering ... if there is a crack , or tension halo due to heat treatment at about 0.5 mm beneath the surface(not surface reatching ) of a sapphir (bleu), can it take the color within the halo like a crack reatching the surface ? thank's .
