Quartz box bowl, also known as quartz crucible, is commonly referred to as box bowl by northerners and crucible by southerners. Quartz box bowls have many advantages, such as high purity, strong temperature resistance, large size but high precision, good insulation performance, energy saving, and relatively stable quality. So how do we use and maintain it on a daily basis.
1. The main chemical component of quartz bowl is silicon dioxide, so it does not react with any other acid except hydrofluoric acid, and is prone to react with caustic soda and alkali metal carbonates.
2. The box bowl has good thermal stability and can be directly placed on a flame for heating.
3. Quartz bowls are similar to glassware and are more prone to breakage, so special care should be taken when using them.
When using a bowl, potassium (sodium) bisulfate or sodium thiosulfate (dried at 212 degrees Celsius) can be used as its flux, but the melting temperature cannot exceed 800 degrees Celsius.
We need to pay attention to the contents mentioned in the above article when using quartz bowls in daily life, so as to make the bowl last longer.
