What temperature do you fire polish fused glass?

Key Temperatures in the Firing Process

What temperature do you slump glass?

What temperature do you need to slump glass? Slumping temperatures are typically between 1200 to 1300 degrees Fahrenheit. The glass will begin softening and turn glossy when the temperature nears 1100 degrees Fahrenheit and will start slumping as it approaches 1200 degrees Fahrenheit.

Can you fire polish and slump at the same time?

Re: Can I slump and fire polish at the same time? yes. for a matte surface, i go to 1225 for 8-10 minutes. the hotter or longer you go, the shinier the surface.

How long does it take to full fuse glass?

How long does it take to fuse glass? Depending on the glass and the size and thickness of the project, it can take anywhere from three to four hours for smaller pieces, and up to 13-14 hours for larger pieces.

What is a fire polish schedule?

A suggested schedule would be: 300 degrees per hour to 1000 and hold for 20 minutes. As fast as possible ramp up to 1300 and hold for 5 minutes. As fast as possible ramp down to 900 degrees and hold for 75 minutes. Then down to 300 degrees per hour to 100 and turn the kiln off.

What is a firing schedule?

The firing schedule is the set of pre-determined stages the kiln moves through from the time it is turned on to the time it has either turned off or has cooled enough to unload. These changes are defined by changes in the kiln atmosphere or the firing ramp.​

What is the difference between a glass kiln and a pottery kiln?

The main difference between a glass kiln and a ceramic kiln is that glass kilns generally heat a single layer from the top and ceramic kilns heat multiple layers from the side. The reason glass kilns were designed to heat the kiln from the top is because the majority of glass projects tend to be relatively flat.

Why is my fused glass dull?

A: This dull white crystalline substance on the surface of your glass is known as devitrification. It can occur when your glass remains in a temperature range 1000F-1300F too long. You need to minimize the time spent in this temperature range.

What is tack fusing?

Tack-fusing is kilnforming technique wherein two disparate pieces of glass are heated until they’re just hot enough to stick together, but not so hot that they lose their individual characteritics or fuse flat.

What is COE 90 glass?

A Coefficient of Expansion (COE) is simply a measurement of the rate that glass will expand and contract when it is heated and cooled. The two main COEs for fusible glass are 90 and 96. The main difference between the two is that 96 is generally softer and fuses at lower temperatures than 90.

How many layers of glass can you fuse?

Then take into consideration the layers of your project. A general rule for a Full Fuse is at least 2 even layers. You can choose Tack Fuse or Contour Fuse IF you are only using one layer and some decorative elements on top of the base layer. Slumping is ALWAYS done AFTER the Fuse firing.
