BLOWTOOL-1

Description:

The Hollow Blow / Puffer Tool is a hand-held blowing tool built with a wooden handle and a graphite cone-shaped mount. The tool is hollow from the end of the handle through the graphite tip, allowing unrestricted airflow while you work. This style of blow tool is used in lampworking and scientific glassblowing when you need controlled internal air pressure to open up tubing, gently expand a hot gather, or fine-tune wall thickness and form without using a full blowhose setup.

How it is used:

Warm the graphite cone gradually near the flame to reduce thermal shock and help prevent glass from sticking. Seat the open end of hot tubing or a hot hollow piece onto the graphite cone to create a stable, centered connection point. Apply gentle, controlled breath through the hollow handle to introduce air pressure and expand the heated glass evenly. Rotate the work while blowing to keep the expansion symmetrical and to avoid thin spots. Use short, repeatable puffs rather than one long blow when you need precise control over diameter and wall thickness. Keep the graphite clean and dry, and avoid overheating it directly in the flame for extended periods.
