Performance & Formulation Insights for GlassMira YG47
Unique Yellow-Green Interference on Calcium Sodium Borosilicate
GlassMira YG47 stands apart from the rest of the GlassMira series by using a calcium sodium borosilicate substrate instead of the calcium aluminum borosilicate found in other grades. This substrate difference, combined with a unique coating system of Titanium Dioxide, Silica, and Iron Oxide, produces a distinctive yellow-green interference that is not achievable with standard borosilicate formulations.
The broad 10–150 µm particle range creates a multi-dimensional effect where fine particles provide smooth base coverage and color blending, while larger particles add visible shimmer flash and dimensional interest. The Iron Oxide component contributes warm golden undertones that enhance the yellow-green interference with additional depth and chromaticity.
Formulation Advantages of the Sodium Borosilicate Platform
The calcium sodium borosilicate substrate offers a different refractive index profile compared to aluminum borosilicate, which contributes to the unique optical character of YG47. The Silica component in the coating system enhances adhesion and stability of the interference layers.
The broad particle distribution makes YG47 versatile across formulation types. In pressed powders, the range of particle sizes provides good cake cohesion with multi-dimensional shimmer. In liquid and cream systems, the broad distribution creates a layered effect where different particle sizes contribute different aspects of the overall shimmer character.
