Blow More Glass Tools - Economy Brass V-Necking Tool

SKU:

ABR-BMGT-BRASSNECKIN

Description:

This economy V-necking tool is a brass, V-grooved shaping tool designed to contact hot glass and pull heat out quickly while creating an even constriction. The V shape supports the work evenly as you roll, helping you neck down tubing or solid work in a controlled, repeatable way. In lampworking and scientific glass work, a V-necking tool is used when you need to create a clean restriction for sectioning, forming a defined neck for transitions, or setting up a controlled break line before separating a piece.

How it is used:

Heat the area of the glass you want to constrict until it is evenly hot and moving.
Roll the hot glass in the V groove while maintaining steady hand pressure and alignment.
Continue rolling until the neck is even and the glass cools and stiffens slightly from contact with the brass.
For a clean separation, constrict the glass, let it cool and stiffen, then gently wobble the glass until it separates along the constricted line.
