Working Together for Better Materials
We'd Love to Hear from You. Every partnership starts with understanding — of challenges, goals and what better can look like. Let’s create cleaner, stronger and more reliable materials together.
APPLICATIONS
Performance Across Industries
From insulation to infrastructure — our anorthosite enhances material performance across industries. It helps manufacturers reduce additives, optimise energy use, and build stronger, longer-lasting products.

Fibreglass
Anorthosite supplies aluminium, calcium, and silica that melt efficiently, reducing energy use while improving fibre strength, durability, and manufacturing consistency
ASPHALT
Anorthosite can be specified as a high-durability asphalt aggregate, offering strong abrasion resistance, stable microtexture, and light surface reflectivity, with friction performance demonstrated through standard PSV and texture testing
Concrete
Anorthosite is suited to concrete because its stable aluminium–silica–calcium mineralogy enhances long-term durability, mix stability, and performance, with potential benefits in optimized, lower-cement formulations
Glass
Anorthosite contains aluminium, calcium, and silica that melt efficiently, reducing energy use while delivering consistent, high-quality glass.
CERAMICS
Anorthosite is feldspathic flux, promoting vitrification, lighter fired colour, controlled shrinkage, and consistent strength and surface finish in ceramic bodies and glazes
Stone Wool
Delivery of Al₂O₃ already bonded with SiO₂ and CaO. Lighter final product colour. Lower melting energy requirement. Stable and highly predictable mineralogy.
