About Zen, 4920

Zen is a soft pastel aqua blue-green borosilicate glass from Glass Alchemy — a pastel counterpart to Tonic with a calm, translucent quality.

It performs especially well in blowout applications and works best in a neutral to oxidizing flame. Because it contains copper, reducing flames will cause reduction shifting.

For longer working times, a thin sleeve of clear is recommended to protect the surface and preserve the pastel base.

If you want a similar look without reduction concerns, try Nimbus.

Working Tip: Work neutral to oxidizing for best results. A reducing flame will cause REDuction.  While this color can be worked without encasement, for longer working times, we recommend a thin sleeve of clear. Be sure not to get this color too hot when in a thin application as to not cook out the pastel base and turn it transparent.  Blow outs work best of the pastel colors.
