Ruby Slippers

Northstar Glassworks is releasing a new color. Experiment #155 Ruby Slippers is a part of our newest line of colors, “the Future Line” and made from batch in Portland, OR. NS-155 is a transparent sparkly red named “Ruby Slippers” after the old school version Northstar made over 15 years ago! This newest formula uses a NS-88 Pomegranate base red with a TAG Stardust sparkle. With little to no air content, this glass is easy to use in all flame atmospheres. As a kiln striking red, it’s recommended to strike for 6-8 hours at 1050f. This color is a great option for overlays and color combos!

Note: The sparkle is hard to capture in photos and looks best in natural sunlight!
