Developed in the late 19th century by a German glass chemist, it has become the standard in laboratories worldwide for one specific reason: its \u003cstrong\u003elow coefficient of thermal expansion\u003c\/strong\u003e. In practical terms, it expands about three times less than ordinary (soda-lime) glass when heated, which reduces internal stress and makes it more resistant to \u003cstrong\u003ethermal shock\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eIt is also prized for its \u003cstrong\u003etransparency\u003c\/strong\u003e and excellent \u003cstrong\u003echemical resistance\u003c\/strong\u003e: it does not react with most everyday liquids and does not retain odors.
