Answer:
Glass blowing is a technique in which molten glass is shaped by inflating it with a blowpipe. The glass is first melted in a furnace at a high temperature. Then, a glassblower uses a blowpipe to gather a small amount of molten glass and inflate it into a bubble. The glassblower uses tools to shape the bubble into the desired form. The glass can be colored by adding colored rods or powders. Once the glass is shaped, it is slowly cooled in an annealing oven.
Some of the key terms in the glass blowing are:
- Molten glass: Glass that has been melted and is in a liquid state.
- Blowpipe: A long, thin tube used to gather and shape molten glass.
- Glory hole: A furnace used to heat molten glass.
- Punty rod: A rod used to support a piece of glass while it is being shaped.
- Marver : A flat, smooth surface used to shape molten glass.
- Shears: Tools used to cut molten glass.
- Annealing oven: An oven used to slowly cool glass so that it does not crack. practice.
