The maximum temperature for quartz windows depends on the specific type of quartz and its purity.
For natural quartz, the maximum temperature for continuous use is about 1,100 °C, while for short-term use it can withstand temperatures up to about 1,300 °C.
Imported quartz tubes, which can be transparent or milky white, can withstand temperatures up to 1,100 °C. These tubes are highly resistant to thermal shock due to their low coefficient of thermal expansion.
It is important to note that when using quartz windows or tubes, it is recommended not to open the door until the temperature is at or below 100°C, unless specifically creating a heated gas for certain processes.
It is also advised to wear gloves when removing materials from the oven and to wait until the temperature on the digital screen reaches 25°C before handling the items.
In terms of baking conditions, quartz can be baked at temperatures up to 1,000 °C for at least 1 hour.
Overall, the temperature resistance of quartz windows and tubes is directly related to their purity. The higher the purity, the higher the temperature resistance. However, it is important to note that quartz can be susceptible to thermal shock on heating and cooling, especially if it is of lower quality or impure.
