Is glass made from water?
Believe it or not, glass is made from liquid sand. You can make glass by heating ordinary sand (which is mostly made of silicon dioxide) until it melts and turns into a liquid. You won’t find that happening on your local beach: sand melts at the incredibly high temperature of 1700°C (3090°F).

What are the 2 main elements in glass?
The main components of the glass batch are:
- silica (sand with particular features), which is the glazing element;
- soda, which is the melting element;
- calcium carbonate, which is the stabilizer.
What is the main source of heat in a laboratory?
The sources of heat in laboratory are: Bunsen burner, spirit lamp, candle, gas stove(portable burner), kerosene stove and electric heater. The Bunsen burner is mostly used as a source of heat in laboratory.
What is the importance of laboratory apparatus?
Science laboratory equipment will allow your students to interact directly with the data that is gathered. They will be getting a first-hand learning experience by performing different experiments on their own. Pupils make use of the models and then understand the different scientific concepts and theories.
Why it is important to follow laboratory safety rules?
Lab safety is one of the most important concerns when you are working with medical supplies, hazardous chemicals, and heavy-duty equipment. Because accidents can easily occur when working in the lab, it is critical to pay attention to the proper care and usage of the supplies you use in the lab.
What does sodium carbonate do to glass?
The major uses of heavy sodium carbonate are as a solid, particularly in making glass, where it is used as a flux in the melting of silica (sand).
What is an apparatus give an example?
apparatus Add to list Share. Your apparatus is the collective equipment you use for specific purposes. For example, the apparatus used for scuba diving includes goggles, flippers, and a breathing tank, while a surgeon’s apparatus includes various scalpels and clamps. Different activities, different apparatuses.

What is glass mainly made of?
Glass is made from natural and abundant raw materials (sand, soda ash and limestone) that are melted at very high temperature to form a new material: glass. At high temperature glass is structurally similar to liquids, however at ambient temperature it behaves like solids.
How do we take care of laboratory apparatus?
To keep your equipment and your lab in great shape, it is important to wipe down the exterior of all equipment each day and do a thorough, detailed cleaning at least once a week. Some types of equipment will need to be cleaned using a specific cleaning process.

How is glass made naturally?
In nature, glasses are formed when sand and/or rocks, often high in silica, are heated to high temperatures and then cooled rapidly. The Glass in Nature display shows specimens of glass made in nature. Obsidian or volcanic glass, for example, is molten rock that has quickly cooled, becoming rock in a glassy state.
