Item Name:
Fused Quartz Tubing - 25mm x 3mm
SKU:
ABRQT74
Description:
This is a piece of fused quartz tubing with a 19mm inner diameter and a 25mm outer diameter. Fused quartz is a high-purity silica material selected for work that demands excellent heat resistance, very low thermal expansion, and strong thermal shock performance. In lampworking and scientific glass work, quartz tubing is used when the application runs too hot for standard glass, when repeated heating and cooling cycles are expected, or when a clean, high-purity material is important for the function of the part. This larger outer diameter provides a thicker wall and added rigidity, which can be useful when making protective sleeves, liners, or structural tube sections that need to hold shape under aggressive heating.
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, keeping the heat even across the working area to 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: 19.00mm
