A dental furnace is a device used in dental laboratories for sintering, firing, or glazing dental ceramics. It is a type of oven that reaches extremely high temperatures (up to 1600°C) for the purpose of heating and hardening materials such as porcelain, zirconia, and other dental ceramics. The furnace has a programmable control system that allows technicians to set and regulate temperature and time settings, ensuring that the firing process is consistent and reliable. The resulting dental restorations are durable, aesthetically pleasing, and can be used in a variety of dental applications, including crowns, bridges, and veneers.
