Firing
How kiln firing fuses your printed designs permanently onto the ware.
About firing ceramic ware
Firing onglaze transfers onto fine bone china is a specialised decoration process that happens after the glaze firing, using a relatively low-temperature firing to fuse the printed or painted design onto the already-glossy glazed surface.
How firing can change the colours
Colour matching: some pigments change slightly during firing, so testing is often needed.
Gold/platinum/silver transfers: these require even more controlled firing, as they're delicate and prone to discolouration.
Firing atmosphere: an oxidising environment is preferred to maintain colour integrity.
Firing temperatures
Firing temperatures vary depending on the ware you're using — see below for reference:
Earthenware: 800–820°C
China body (thick): 820–840°C
Bone china (thin): 820–840°C
Porcelain: 840–890°C
Stoneware: 840–890°C
