Hints and Tips When Working With Glass
Published on 11/11/2025 in Secondary

We know, as a technician, you often have to do a lot of DIY so we wanted to try and help by offering you any hints and tips we come across from our team and other technicians we speak to. This first one comes from our resident technical support advisor, Jackie and offers a few hints on working with glass.
I would always recommend the following
Cutting glass tubing:
Scratch the tube or rod at the desired point with a specialised glass cutter
Wrap the tubing in a protective cloth to avoid cutting your hands. Place thumbs together opposite scratch
Using little force, pull back on the tube and push thumbs outward quickly to break the glass
Glass bending:
Protect hands from the heat
Use a flame spreader on the Bunsen burner adjusted to a roaring flame
Hold the tube lengthwise in the flame and rotate back and forth evenly until the glass becomes soft
When the glass is soft and bends under its own weight, remove from the flame
Bend into the desired shape, holding in position until hardened
Inserting glass tubing in stoppers:
Wet the tubing and stopper hole with water or glycerol
Wrap hands in towel for protection
Grasp the tube near the point of insertion
Rotate the tube back and forth while gently pushing it into the stopper
