What is the viscosity of rocks and of metal when they are molten?
The viscosity of molten rocks can vary widely depending on factors like temperature and composition, but typically ranges from 10^2 to 10^6 Pa·s. Molten metals generally have lower viscosities compared to molten rocks, typically ranging from 10^-2 to 10^2 Pa·s, due to the metallic bonding that allows for easier flow.
What is molten glass?
Molten glass is glass that is heated to a high temperature until it becomes a liquid. This allows the glass to be shaped or molded into various objects or forms before it cools and hardens back into a solid state. Molten glass is commonly used in glassblowing and glassmaking processes.
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.
What are the characteristics of a felsic and mafic rocks?
Felsic rocks are light-colored, rich in silica and aluminum, and have high viscosity when molten. They contain minerals such as quartz and potassium feldspar. Mafic rocks are dark-colored, rich in magnesium and iron, have low viscosity when molten, and contain minerals like olivine and pyroxene.
What are the streams of molten lava spilled out of a volcano called?
Streams of molten lava out of a volcano are called 'lava flows'.
What is the viscosity of molten aluminum?
It is about 0.005 Pa.s
What affects the viscosity of a molten material?
The viscosity of a molten material is affected by factors such as temperature, composition, and any impurities present. Higher temperatures generally decrease viscosity, while certain elements can increase viscosity by forming strong chemical bonds. Impurities tend to disrupt the flow of the material, leading to higher viscosity.

Why is viscosity important for glass blowers?
because if it wasnt the right viscosity, the glass will be too hard for the blower :p

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?
How do you make glass in RuneScape?
You get seaweed, and bake it on a stove to get soda ash. Then you take a bucket of sand and the soda ash to a smelter and combine both to get molten glass, once you have the molten glass you can get a glass blowing pipe and there you have it, glass.

Is glass waterproof?
No. It is a solid. Even molten glass is not soluble in water.
Why did they call glass makers flints?
* Battledore - a flat wooden paddle used to shape molten glass objects * Blowpipe - a long, hollow, rod that shaped glass objects * Caliper - used to measure the size of a molten glass object * Crucible - a fire-resistant clay pot in which glassmaking objects were melted * Lehr - a special oven used to strengthen the glassware * Pincers - pliers used to stretch and squeeze glass * Pontil - a long metal rod connected to a molten glass object to help hold it * Pucellas - tongs used to twist and stretch a molten glass object * Shears - scissors for cutting and trimming a molten glass object
How doe you make glass like is it made from ice or rocks or what?
The basic recipe for glass is silicate (sand) melted with a bit of bicarbonate of soda. The molten mass created is molten glass, which is then processed in whatever way is necessary to make the final glass product.
How do you use molten in a sentence?
The molten lava flowed out of the volcano, They used molten glass to make the ornament.
