Replaceable Tungsten Straight Rake/Poker- 3/32"

A Tungsten Pin Vise and a 3-¼" Tungsten Rod together. The length that the tungsten extends from the handle can be adjusted from 1" to 2-3/4". Used to poke holes in glass, make small bubbles, rake and "drag" glass for feathering, marbling, etc. To poke holes in glass, warm the glass, but not hot enough to distort or glow red. Then heat the tungsten rod until it glows bright red and push its point into the glass. Repeat this process until the hole is complete or maintain the flame on the tungsten near the glass while pressing the tip into the glass. If done properly, tungsten will not stick to glass like other metals do. Note: Tungsten is very brittle and will snap rather than bend. The 1/16" size is especially delicate. A hole made with tungsten is smaller than a hole made with the corresponding size of mandrel, because it has no mandrel release on it to add thickness.
