Item Name:
Fused Quartz Tubing - 300mm x 5mm
SKU:
ABRQT194
Description:
This fused quartz tubing is clear, high-purity quartz glass tubing produced as a straight, round tube with a consistent inside passage and outside diameter. In lampworking and scientific glass work, fused quartz is selected when you need excellent thermal shock resistance and stability at high working temperatures, particularly for components that will be heated and cooled repeatedly. A large diameter tube like this is typically used when the project requires substantial internal volume, high airflow capacity, or a large working envelope for forming, flaring, and joining larger assemblies.
How it is used:
- Preheat slowly and evenly while rotating to bring the full circumference up to temperature and reduce thermal shock risk.
- Support the tube during heating and keep it moving to help prevent ovaling and sagging as the quartz softens.
- Use controlled heat zones to open, flare, or shape the end for large transitions, collars, or wide-mouth connections.
- Fuse to compatible quartz components by heating both parts evenly and joining with steady rotation to maintain alignment and roundness.
- Anneal according to fused quartz working practice for the wall thickness and overall mass of the finished assembly to reduce internal stress.
