What is Crucible Tongs? Crucible tongs function is widely found in a science laboratory equipment or industrial equipment to handle a hot crucible, evaporating dishes, flasks, small beakers or other items which have a high temperature or contain potentially dangerous materials which cannot be touched with bare hands.
What are metal tongs used for?
Arguably the most widely used and versatile type, utility tongs are suitable for flipping or turning foods during cooking, removing cooked foods from boiling water and handling hot foods from the oven or grill. Most often, these tongs are made of metal, stainless steel or plastic with a scalloped tip for better grip.

What is a flask used for in science?
Flasks can be used for holding and measuring solutions, as well as for chemical reactions and phase changes (heating, cooling, etc). Flasks are normally the site of chemical reactions, for the reaction can take place in the large vessel and have low risk of spilling due to the long, narrow neck of the flask.
What are science glasses called?
Beakers are the workhorse glassware of any chemistry lab. They come in a variety of sizes and are used for measuring volumes of liquid.
What are round beakers called?

Is borosilicate a glass?
Borosilicate glass is a type of glass with the main glass-forming constituents’ silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion (∼5 × 10−6/ °C at 20 °C) making them resistant to thermal shock more so than any other common glass.
