Slip-casting times

White earthenware: 20 – 30 minutes. Firing temp 1000°C to 1150ºC (1832°F to 2102ºF)

Red earthenware: 20 – 30 minutes. Firing temp 1000°C to 1150ºC (1832°F to 2102ºF)

Stoneware: 45 mins – 1 hour. Firing temp 1160°C to 1290ºC (2120°F to 2354ºF)

Semi-porcelain/ high-firing white earthenware: 20 – 30 minutes. Firing temp 1100°C to 1260ºC (2012°F -2300°F)

Porcelain: 5 – 10 minutes. Firing temp 1260°C to 1280ºC (2300°F to 2336ºF)

Bone china could be added to this list, but it’s not a slip to choose when first starting to experiment with slip casting, because it requires special firing treatments and is notoriously difficult to handle. If you have no prior experience of casting, start with white earthenware because it’s easy to cast and fire, and is the cheapest option.
