Glassblowing and Glass Production
There are several methods of making glass. One of these is glassblowing. Glassblowing uses air to inflate molten glass into various shapes. This is sometimes done with tubes and a person blowing into it. On a broader scale, this is sometimes done by machine. Glass can also be created through molds, casts, or rolling.

This information on blowing glass is taken direct from WikiHow:
Glassblowing is the process of creating artistic glass works through the manipulation of molten glass. This style of glassblowing is also called off-hand or furnace work. Off-hand glassblowing requires an extensive collection of equipment and tools.
Steps:
- Gather - Collecting glass from the furnace; the closest analogy to gathering is turning caramel onto an apple.
- Marver - Shaping the glass on a steel table into an even, on-center cylinder.
- Cap - Blow into the pipe and cover the hole with your thumb to trap air inside the pipe. The bubble will begin to inflate.
- Gather again - Collect more glass around the bubble.
- Shape and Inflate the form
- Add a Neck-Line
- Finish the shape and flatten the bottom.
- Tranfer the piece onto a punty for finishing the top part.
- Heat the lip and flare open.
- Knock the piece off the punty and put into an annealer for slow cooling.

What type of glass production accounts for the majority of flat glass production?
The Pilkington Float process
Why is viscosity important in glass blowing?
It is important because if the glass is kept at a little bit more than medium viscosity. It can be manipulable, thus blowing glass. U mad bro?
What property of glass means that it's not a perfect material for making windows?
Glass is brittle, it breaks when bent or hit, curved windows are made that way when the glass is still hot ans malleable, once it cools it becomes brittle.
Why do we recycle soda lime glass?
The making of soda lime glass is expensive to compare then recycle sodalime glass . Main component for making soda lime glass is silica. for melting silica required toomuch temperature & other component which soda lime glass required are also much expansive. but recycled soda lime glass required low temperature for melting to shape it again at low cost . so we recycle soda lime glass.

Where can I find out about Glass blowing classes in Venice Italy?
I can only find a site about lessons in Poughkeepsie, NY
What are the names of the furnaces used in glassblowing?
Modern glassblowing involves three furnaces. # 'The Furnace' holds the molten glass. # 'The Glory Hole'reheats the glass between molding/blowing processes. # 'The Annealer' is a 'cooling furnace'. The cooling strengthens the final product.
In which countries is glass blowing still a very profitable profession?
Glass blowing is still practiced and indeed is very profitable in a varied selection of countries, including USA, UK, Japan, China and the Netherlands. It is associated as a technique under the 'Glass Sculpture' movement whereby glass is used in art, the resulting pieces are commonly displayed at exhibitions where they can command a very significant price.
well what you will need is a special coloured film two diffrent colours like one red one blue and make them in to to large squares but not very large then get some card and do a glasses shape but where the lenses are ment to go cut a rectangle /square in them then glue round the sides of the square peices with super glue and stick them to the glasses there you go you have home made glasses now get a 3D movie and try !!!!!!!!!!!!
Has vinyl plastic replaced glass nowadays?
No polycarbonate plastic and acrylic plastic make a better replacement for glass than vinyl. There are also some applications for which nothing replaces real glass.
Not necessarily. If a body has the same charge as a glass rod (negative), it means the body is negatively charged. The charge is determined by the excess or deficit of electrons on the body.
Do dislocations control the strength of silicate glass?
No,it is flaw size that control the strength.
Glass blowing is a technique where molten glass is shaped by inflating it through a blowpipe. The glassblower gathers molten glass from a furnace onto the end of a blowpipe, then blows air through the pipe to shape the glass. By rotating the pipe and using various tools, the glassblower can create different shapes and designs.
