because if it wasnt the right viscosity, the glass will be too hard for the blower :p

How does the silica content of lava impact its viscosity?
Silica content is directly proportional to viscosity, so the higher the silica content of a lava, the higher its viscosity. high viscosity means a lava will be thick and slow moving, hence probably meaning an explosive eruption. lava's with a high viscosity include rhyolite and andesite whereas lava's with a low viscosity (runny ones) include basalt.
What education do you need to be a glass blower answer?
Education will not be as important as getting the opportunity to begin work as a glass blower and then take classes pertaining to the glass blowing occupation over time,
Why do they put lead in glass?
Lead, in the form of lead oxide, PbO, is added to glass to stabilize the matrix and improve the working characteristics of the glass. As a flux, PbO lowers the melting point considerably, and it also decreases the viscosity of the material. Additionally, lead oxide changes (increases) the refractive index of the glass.

How do you calculate the viscosity index of a petroleum product with viscosity at 40 degree centigrade and is less than 2 cst?

What is the difference in silica content and viscosity between light-colored and dark-colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
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 is construction of capillary viscometer?
A capillary viscometer is constructed from glass. Glass blowers make different styles of capillary viscometers with specific bulb and capillary diameters. These dimension determine the viscosity range of liquids which can be tested.
Who did colonial glass blowers make glass for?
england
Where can one find professional glass blowers in the city of Minneapolis?
It is possible for you to be able to find professional glass blowers in the city of Minneapolis by travelling abroad to that place, and going to places like Target.
Why does a glass blower need to know about viscosity?
Viscosity is a measure of the rate at which a liquid changes shape under an applied stress. (units of measure: poise) The viscosity of glass changes rapidly with temperature. At high temperatures the viscosity of glass is low and it can be shaped easily. As the temperature is lowered the viscosity of glass increases.
Who is the patron saint of glass?
There is no patron saint of glass. Saint Lucy of Syracuse is the patron saint of glass blowers, however, and she and Saint Luke are the patron saints of glass makers.
Does glass have a definite shape?
No, it can be manipulated when at around 1500ºC, It becomes soft and glass blowers can manipulate it to become what ever shape they want it to be.
What are glass blowers?
Glass blowers are craftsman that create pieces of glass. Automation and the advent of plastics have greatly reduced the number of active glass blowers. The vast majority are now artists that use long metal pipes to blow bubbles into molten glass. By shaping the glass, adding colors, attaching handles and bases and other key items, they create unique works of art that are used as vases, glasses, pitchers, and any other sort of container that can be formed with glass. Some still use metal molds that force the bubble into a specific shape, the way most early glass bottles and containers were created. Glass blowers were actually some of the first craftsman in North America. One of the first industries in Jamestown was a glass factory.
What has low viscosity?
Liquid helium has practically zero viscosity. Pretty cool to see, it seeps through glass cups and containers.
What has the author William Ernest Stephen Turner written?
William Ernest Stephen Turner has written: 'The constitution of glass' -- subject(s): Glass '... The elements of glass technology for scientific glass blowers (lampworkers)' -- subject(s): Glass, Glass blowing and working
Why you checking viscosity?
Viscosity is an important parameter for materials in industry; it is useful to know the flow behavior.
How in the knowledge of viscosity applied on a candy maker?
its not important
