Nessler glass, also known as Nessler's tube, is characterized by its distinctive yellow-brown color, which is due to the presence of copper salts used in its composition. This glass is notable for its high resistance to thermal shock and chemical durability, making it suitable for laboratory applications, particularly in colorimetric analysis. Additionally, it has a relatively low refractive index, allowing for precise optical measurements. The glass is often used in the determination of ammonia concentrations in water through visual comparison methods.
