- Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about 165 °C (300 °F). It is commonly used for the construction of reagent bottles and flasks as well as lighting, electronics, and cookware.

Slovenia (/sloʊˈviːniə, slə-/ sloh-VEE-nee-ə; Slovene: Slovenija [slɔˈʋèːnija]), officially the Republic of Slovenia (Slovene: Republika Slovenija, abbr.: RS), is a country in southern Central Europe. Slovenia is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and a short coastline within the Adriatic Sea to the southwest. Slovenia is mostly mountainous and forested, covers 20,271 square kilometres (7,827 sq mi), and has a population of 2.1 million (2,110,547 people). Slovenes constitute over 80% of the country’s population. Slovene, a South Slavic language, is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. A sub-mediterranean climate reaches to the northern extensions of the Dinaric Alps that traverse the country in a northwest–southeast direction. The Julian Alps in the northwest have an alpine climate. Toward the northeastern Pannonian Basin, a continental climate is more pronounced. Ljubljana, the capital and largest city of Slovenia, is geographically situated near the centre of the country.
