Terra 3 is a dual colour; capable of reducing or striking. This reformulated version uses DoubleHelix's newest nucleation system, the same as Skylla, Skiron, and Ekho2. The new nucleation system results in glass that is easier to strike.

Terra 3 can be used as a surface luster, struck on the surface, or struck under a thin encasement layer.

The cooling and warming portions of the striking sequence for this glass are both approximately 45 seconds. Specific times may vary depending on several factors. For best results in a striking application, apply a thin layer of clear glass to encase, then reset the Terra 3, cool, and strike the colour through the clear.
