Fusing Glass

by Bisque Imports

Loading The Kiln

All kilns fire differently, so be sure to test fire your own kiln to find the best method for you! Here are some tips from experts to help you out as your begin:

Try staggering the kiln shelves to allow for more airflow and even distribution of heat within the kiln.

Leave a few inches between the top of your mold/glass and the next shelf. This also helps with airflow.

Do not load too close to the kiln lid. Allowing at least 5 inches of open space is recommended.

Generally the kiln is coolest towards the bottom. Keep this in mind when you load the kiln. Place items that require more heat to slump properly closer to the middle and top (like bowls).

Setting The Temperature

Determine which temperature is appropriate for your project (full fuse or tack fuse) and set your kiln accordingly. You may refer to the firing guide below; however, you may need to adjust the temperature since all kilns fire differently due to individual conditions.

Full Fuse - Fusing is joining two or more pieces of glass by heating them until they combine. Fire to 1450-1550F / 788-873C / Cone 014.

Tack Fuse - Tack fusing is fusing until the glass just sticks together, with each piece retaining its individual characteristics. Tack fusing does not require the glass to e an even two layers. Fire to 1350-1450F / 732-788C / Cone 017.
