Dear all, I need to have some thin sections or sample slabs made of porous rocks (sandstone, carbonates) that have the following specifications: max size 10x10 mm no glue/epoxy, at least not in/under the centre of the sample no cover slip (or a removable cover slip) on top Sounds difficult to me... Alternatively, a slab (not mounted as a thin section) with the following specs: max size 10x10 mm max thickness 2 mm The challenge here is to get this made without destroying the material, and without the use of epoxy. Clearly that rules out some of the more friable porous rocks. Anyway - I do not have any experience with the preparation of samples or thin sections this small and delicate, so any suggestions as to where you think I could get this done would be much appreciated!
