This furnace, also called a bisque firing kiln, conducts the initial firing of ceramic ware to transform shaped clay into a durable, porous bisque. Operating around 900°C, it drives off physical and chemical water and begins vitrification. The working principle involves a controlled ramp-up of temperature to prevent steam pressure from cracking the ware, followed by a soak period and controlled cooling. Its purpose is to harden the clay body so it can withstand handling and the absorption of liquid glaze before the final firing. It is a fundamental first step in all professional and studio pottery production.
