So, back in the days before we had digital controls for kilns, we kiln gods and goddesses used to have to monitor the firing temperature using pyrometric cones. Here’s a video – only about 1:30 long – that explains how this process works.
These cones came in a box. (We have some of these boxes in the studio.) Manufactured by Orton Ceramics, the standard size for these boxes was 3″x3″x6″. And one of my favorite NCECA shows, the International Conebox Show, is a biennial (meaning every two years) juried show of miniature ceramics. All pieces must fit within a conebox! The detail on these stunning little pieces is amazing. You can see more pictures of award winners or learn more about the exhibit at this website.
