Hyperborea has a rich violet and red colour transmission and easily develops a strong silver luster when reduced.  It works well both in surface applications and under encasement.  The colour is saturated and may present best over a core of clear glass, as pictured.  A replacement to Boreas, Hyperborea is made in our updated colour base resulting in cleaner colours, smoother working characteristics and improved viscosity curves.  Based off of the BE test batches.

All tested compatible with Effetre Clear 104 coe. Rods are 5mm in diameter.
