Hi,
just wondering if there is a recommended drying time pre firing?
Thanks a Million

Respuestas de Scarva:

Drying time will depend on how small or big your piece is and the ambient room temperature most work takes around 3-4 days but this can always be slowed down by wrapping in plastic if so desired, there are no pre-defined rules and every piece can be different. In order to determine if a piece is dry simply feel it; if it feels cold it still contains moisture and requires further drying, if it feels warm it is dry and ready to be fired in the kiln.

Hello, I was wondering if this clay is suitable for handbuilding? Many thanks!

Respuestas de Scarva:

You can handbuild with this clay however it is quite fine so you may be restricted in terms of how large you can make, hope this helps.

Could you please tell me if this might be suitable for creating drinking vessels, i.e. food safety-wise.

Providing the body is fired to maturing temperature and with a suitable glaze it is ideal for tableware.

You could turn this clay into a casting slip by adding some sodium silicate and water yes however it would take some preparation to do this.

Hi. Is the shrinkage similar to stoneware or almost as much as porcelain? Thank you
|
Respuestas de Scarva:
|
Hi, no this clay body has a much lower shrinkage rate than traditional porcelains, in our testing it's around 8-9% at cone 8. Hope this helps!

Please could you tell me what temperature PF700 Porcelain White Stoneware should be glaze fired at? Is 1220°C too low? Thank you!
|
Respuestas de Scarva:
|
1220°C is an ideal temperature however you would be best deciding the final firing temperature based on the glaze opposed to the clay this will ensure the glaze is fully matured giving better results.

Firing Temp 1220-1300ºC
