Meta-Terrania ABNORMALS - Molten Aura Labs
Meta-Terrania is an aqua-colored AuraTone™ This landmark color has been completely reformulated and joins our growing palette of beautiful SANDCRAFTED® colors. Neutral to slightly reducing flame recommended, depending on your torch. Strong reducing flames will bring out copper tones. A clear encasement can be helpful to avoid copper precipitation.
Garage often and give the piece plenty of soak time based on its size and shape.
Recommended Garage/Anneal temp 1100°F
Meta-Terrania is a transparent turquoise colored glass. We added some haziness to enhance its briny, sea water quality. Thicker areas tend to exhibit this hazy quality more. Careful flame striking can bring out more of the haziness and make the color appear more blue.
This color doesn't like too much oxygen. You may get a “scuzz” showing up with a flame that is too aggressive. It can be minimized and usually avoided by a more reducing flame and/or by burning off the layer of “haze” that develops. This is similar to an amber/purple color in that the metals giving the glass it's color are precipitating to the surface when the glass reaches a certain working temperature. Encasing in clear can eliminate surface issues as well.
There may be variances in the color and density of the rods – even from the same batch. This does not affect the final worked color.
***ABNORMAL : color is sightly more opal/opaque compared to first quality Meta****
Always begin working Meta-Terrania in a reducing flame, after a core heat has been achieved, a more aggressive neutral flame can be used. Heating too aggressively with too much oxygen present will cause a film to develop on the surface at the edge of the puddle. For some seals one will need to use an aggressive flame.
To avoid buildup, while using an aggressive flame, switch back to a reducing flame and flash the area near the edge of the puddle keeping it hot, but still cool enough to maintain structure. If any film does develop, a coating of soot followed by a slow heating until completely molten can totally reverse any surface issues.
PLEASE NOTE: This glass is below first quality and has been deemed Abnormal. Rods may be oblong, slightly thick or thin, or have other imperfections causing their odd appearance.
