Why is quartz glass used in laboratories instead of ordinary glass?
Quartz glass is preferred over ordinary glass in laboratories for several reasons.

Firstly, quartz glass has a higher melting point and is more resistant to high temperatures, making it suitable for applications involving extreme heat, such as in furnaces or flame-based experiments.

Secondly, quartz glass has excellent optical properties, allowing for better transparency and minimal distortion of light, which is crucial for experiments involving spectroscopy or microscopy.

Additionally, quartz glass is highly resistant to chemical corrosion and can withstand exposure to a wide range of acids, bases, and solvents, making it ideal for handling corrosive substances in a laboratory setting.

Lastly, quartz glass has low thermal expansion, meaning it experiences minimal dimensional changes with temperature fluctuations, ensuring the accuracy and reliability of measurements. Overall, these properties make quartz glass a superior choice for various scientific and experimental purposes in laboratories.
