— I have balls I cast maybe 20 years ago, and they remain in the unopened jars, nice and bright. But if you are in the habit of often opening the jars to remove a few balls, you are putting fresh oxygen into the system, and the process begins anew. It works for long term storage, which is why I use smaller jars, holding maybe 8oz by volume.

This is what gives you smooth consistent lines when you hold a pencil and drag it across paper. Because graphite is soft and brittle, a casing is required to hold the material. Artists use graphite, not just in pencil form, but in powder form too. In powder form, graphite can be applied to paper using a brush, sponge or tortillion.

— The shear modulus of graphite is 2.3 GPa [1], and the theoretical shear strength of a crystal, σ th, is about μ/30 [7], which yields σ th =77 MPa for graphite. On the other hand, the shear pressure generated by normal ball-milling machines varies from 2 to 6 GPa [8], which is high enough to shear the graphite sheets directly.
