BE - 1859 Rhubarb Shift Tint Rod
Though it depends on somewhat on the light source, this glass is typically green where thin and pink where thick.
Hues of shift colors change depending on light source (natural, incandescent, LED, or fluorescent) and sometimes thickness, regardless of whether they have been fired or not.
Torch: A stable tint that is not prone to reduction in a neutral flame.
Kiln: Working properties and kilnformed characteristics are consistent with sheet glass. See sheet glass notes for this style.
Finished work will have the same color shift properties found in the cold glass. When used in small amounts, the shift between green and pink in this rare earth glass is subtle. The color shift becomes more dramatic in thicker applications and depends on the light source. In mixed types of light it appears to be brown. Not a striking glass.
