Spruce Pine, North Carolina, USA

We didn’t choose Spruce Pine, it chose us. The idyllic mountain town located in Western North Carolina is home to our US headquarters because of the rare geological makeup of the Blue Ridge Mountains. Here you will find the highest purity quartz formations in history. Like the unique gems and minerals hidden in our backyard, we stay tucked away, unassumingly providing the world with a path to the future.

Our community is deeply rooted in mining, arts, and outdoor adventure. It is with this adventurous spirit that we seek collaboration with our colleagues and partners across the globe. For more information, visit our Spruce Pine facility page.

Our Products
IN ACTION

COATINGS

Good dispersability, high chemical inertness, stable pH, high resistance to abrasion and low viscosity makes our Minspar feldspar products ideal for use in coatings.

TABLEWARE

Minspar feldspar offers good fusibility to produce products without defects.

ENGINEERED STONE

Our sand mined in Spruce Pine has excellent visual and physical properties, which help to make the engineered stone slabs more durable, more flexible, and harder than natural stone products.

RUBBER & ELASTOMERS

Minspar feldspar offers good disperability, high chemical inertness, a stable pH, high resistance to abrasion, and low viscosity when added to rubbers and elastomers.

TILES

Minspar feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase while providing a white fired colour.

SANITARYWARE

Minspar feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase.

FIBRE GLASS

Minspar is used as a fluxing agent in fibre glass, reducing the melting temperature of quartz and helping to control the viscosity of the glass.

ELECTRICAL PORCELAIN

Minspar feldspar has very high consistency, high levels of plasticity, and high mechanical strength, making it ideal for use in electrical porcelain.

ROOF COATINGS

Minspar feldspar offers colour consistency, excellent tint retention, ease of dispersion, resistance to fading, chalking and cracking, as well as excellent exterior durability and chemical resistance to roof coatings.
