Item Name:
Fused Quartz Tubing - 21.6mm x 1.8mm
SKU:
ABRQT72
Description:
This is a piece of fused quartz tubing with a 18mm inner diameter and a 21.6mm outer diameter. Fused quartz is a high-purity silica material used when you need excellent heat resistance, very low thermal expansion, and strong thermal shock performance under repeated heating and cooling. In lampworking and scientific glass work, quartz tubing is selected for applications that run too hot for standard glass, where dimensional stability matters under intense flame, or where a clean, high-purity material is important for the function of the component. This size is well suited for fabricating or repairing quartz tube assemblies, making sleeves and liners, and building parts that need to maintain shape while being worked hot.
How it is used:
- Cut the tubing to length using quartz-appropriate cutting methods, then clean thoroughly to remove dust and handling residue.
- Heat and work the quartz with an oxygen-rich torch setup suitable for quartz, rotating consistently to keep the heat even and reduce stress.
- Use the tubing as a body tube, sleeve, or liner depending on the build, then anneal according to quartz-appropriate practice to minimize internal stress.
Dimensions:
- Inner Diameter: 18.00mm
