I am not normally a fan of the web comic XKCD, but I had to post this. My friend Anna who is not a ceramist but who is Russian sent me this. Ceramists are one of the few groups in America to use the metric system (along with drug dealers, hmmmm). There is one area where ceramists still use English and that is in our firings. Please people, use metric. Cone 10=1305 (or 1300, to be brief) Cone 6= 1243 (1250) and Cone 04= 1077 (1075).
