Thin Section. To attain the proper sample, a thin section preparation service cuts a tiny portion of a rock, bone, wood or other substance and grinds it until it is optically flat. The sample is cut with a diamond saw to ensure the cleanest, quickest cut possible without degrading the sample through scorching or pulverizing.

Here is how a thin section is made: A chip is broken or cut from the rock. One side of the rock chip is flattened (by sawing and grinding) and is glued to a glass slide, usually with epoxy. The rock chip is trimmed with a special rock saw, and then thinned on a grinder. This produces a thin slab of rock glued to the
