A glassmaking oven is called a furnace. Furnaces are used to heat materials to high temperatures. Furnaces are also used to melt and formed glasses.
Frequently Asked Questions
What is a glass-making oven?
A glass-making oven is a type of furnace used to melt and even anneal glass. Annealing is a process where glass is toughened through heating and slowly cooling after. Annealing is important because it makes the glass less brittle, allowing it to be formed into more intricate shapes. Without an oven, it would be very difficult and time-consuming to anneal glass.
Why is glass annealed in a lehr oven?
Glass is annealed in a lehr oven because it has a relatively low solidification temperature, meaning that it can be melted and partially solidified without undergoing full solidification. Thisproperty makes it possible to gradually cool the glass in the oven without fully cooling it, which weakens anyurities or crystalline defects in the glass.
What kind of Furnace is used for glass making?
The furnace used for glass-making is a natural gas or fuel oil fired furnace.
What is the process of glass production?
In the float glass process, molten glass is brought to a temperature just below its molecular boiling point. Then, it is poured into cold water and left to cool slowly. This process causes the liquid glass to form tiny bubbles on the surface that grow until they burst, creating small sheets of smooth glass. The bubble activity also strengthens the glass's bonds between atoms and makes it more resistant to breakage. The floating-body method is used to produce sheet glass. In this process, molten glass is poured into an heated mold and then allowed to cool slowly. The metal mold contracts and pushes the glass towards the edge, where it cools quickly and forms large sheets.
