Processes of glass making?

Does a chemical reaction take place when glass is formed?

    yes, when any material is being formed that is not natural, a chemical reaction is being taken place. Look in google or wikipedia to find out how glass is made

    According to Robert H. Doremus, professor of glass and ceramics science at Rensselaer Polytechnic Institute in Troy, N.Y., commercial glass is about 70% by weight silica (SiO2). This compound is obtained from sand and is ideal for making glass because it does not absorb visible light, making the finished product transparent. The glass in fiber-optic cables is made of pure silica because its high transparency speeds the transmission of photonic signals.

    Melting pure silica requires temperatures up to 2,000 °C, so most manufacturers save fuel costs by mixing raw sand with about 18% sodium carbonate (Na2CO3), also known as soda. The carbonate brings down the melting point, but the added sodium causes the finished glass to dissolve slowly in water. Adding about 10% limestone (CaCO3) contributes calcium, which helps protect the glass from weathering. Heating these ingredients together yields a molten mix of calcium silicate (CaSiO3) and sodium silicate (Na2SiO3) that, when cooled under controlled conditions, creates what is known as soda-lime-silica glass.

    i just want to know if there is any chemicals reactions take place in the making of glass

    What kinds of reactions occur during the process?

    What the fuck is wrong with you people my question is to tell me the name of the chemical reaction that takes place when making glass.
    I’ll fuckin turn all of you to vagina’s and eat you guys hard.
    Good job guys yall can be happy for getting raped

    No. Glass is an amorphous (not crystalline) product made from inorganic salts, namely silicon dioxide, and depending on the application, lead oxide, boron salts, alumina, and sodium oxide. The amorphous nature results from the salts being heated, and then cooled rapidly so that crystallization does not occur. The process of making and working with glass is a complex manipulation of physical states of molecules, not chemical changes.

    The idea that glass at room temperature is a viscous liquid that flows over time is an urban legend. GLASS IS A SOLID!! The myth stems from the fact that old windows were sometimes thicker at the bottom then at the top. This was a result of the manufacturing process, not of gravity. Glass blowers used to make sheets of glass by spinning a glob of molten glass into a large circle w/ centrifugal force, then cutting square panes from that sheet. The glass at the edges was usually thicker than in the center, and it would make sense to think that it would be installed thick edge down.

    Modern glass is uniform in thickness and is made by floating molten glass over a molten zinc bath to ensure uniformity.

    Don’t worry, your coffee table top is perfectly safe, and is not sagging.

    Depends on the glass, there are many types, but normal plate glass no…you just melt the silicon…it recompines as a liquid…glass just flows very very slowly….like a glass coffee table will deform over a few months years and you need to flip it.

    From reading about it i would deduct that the type of chemical reaction occuring is combination.
