Gemini is a collaboration between Northstar Glassworks & Gaffer Glass. As a stable, air free glass with buttery smooth working properties, it will present a beautiful, clean purple in natural light. This glass is CFL reactive and will shift to a light cobalt blue using a CFL with 2700K. This glass can be scratched easily causing surface bubbles, please handle with care.

Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.

Top-tier CFL shifting color. A nice purple to faint light blue shift with excellent buttery working properties. It's also optically very clear but that means small flaws stand out more than usual.

Forgiving and fun


This a very easy color to work. Super fun layering over other colors to discover different shifts than the original blue to purple.

looking for a quality purple? buy this one!


Suuuuper nice purple! Here are some reasons why Gemini is my favorite purple to work with:<br>- no air content<br>- nice strong purple that isnt over/under saturated<br>-works well for blown and solid work <br>- CFL shift is pretty sweet (purple--- super light blue which almost looks clear)

Great stuff


Heats up well and easy to work with
