I want to produce porcelain products that are bisque finished. Do I need a higher bisque firing or just the normal temp?
I will be using them as incense and night light holders so they don’t need to be glazed.

Hi, ideally you would still need to fire the piece to maturity to acheive the strength in the body and to be able to wipe them clean without the body absorbing water. You can fire to stoneware without glazing no problem, the body will still vitrify and have a matt white appearance.
Hope this helps!

Thank you for answering my last question. To continue on the same theme, do I need to do a lower temp bisque firing before refiring up to stoneware or can I just fire once straight to stoneware and skip the lower temp firing altogether?

Hi, providing the piece is dry enough, you can fire straight up to stoneware, no need to fire twice. Should there be any worry about the pieces having any moisture still within, you could fire the first ramp slowly to drive out any remaining water. Hope this helps!

I would like to make some decorations that hold essential oil drops.
I’m thinking of just bisque firing but worried that dust will come off the decorations. Would you be able to recommend a glaze firing temp that would still allow for some porosity, if possible?

Around 1160-1180oC should be enough to lower the porosity of the porcelain clay while remaining suitable for your application.

Firing Temp 1220-1280°C
