05 The (Kiln) Bakery
August 13, 2025Every Pottery piece undergoes 2 long baking (firing) processes that can take up to 48 hours of continuous firing and cooling before being a certified food lover! (food-safe)
Baking Processes:
1. Bisque Firing (Up to 900 degrees celsius)
2. Glaze Firing (Up to 1200 degrees celsius)
With each temperature varying from the glaze and clay body being fired.
Bisque Firing
As the kiln reaches 900 degrees celsius during this 8 to 12 hour process, any remaining free water molecules present in vessels are first baked off, followed by the burning out of any organic materials and chemically bonded water.
This effectively strengthens the clay body while keeping it porous enough to absorb glaze in the following stages. Leaving behind a light and pink, beige, or white vessel, depending on the clay used.
Glaze Firing
After evenly coating the bisque fired piece in your choice of glaze, the piece then undergoes glaze firing which can reach blazing temperatures of 1100 to 1305 degrees celsius.
At these temperatures , the clay particles undergo a process called sintering, essentially melting and fusing all the clay particles, as well as vitrification of the silica molecules, the primary ingredient for glass, in the clay body and glaze, leaving behind a nice glassy *ting* and pop of colour to each piece.
