Egyptian feldspar with high alumina and alkali content for glass manufacturing, ceramic tile production, and industrial applications.
Feldspar is a key flux in glass production, reducing the melting temperature and providing alumina which improves the chemical durability, hardness, and weather resistance of the finished glass.
The largest single market for feldspar worldwide. It forms the glassy matrix in ceramic tile bodies during firing, providing mechanical strength, low water absorption, and dimensional stability.
Used in fine china, bone china, and vitreous china bodies to develop translucency and whiteness. Also a flux in the vitrification of sanitaryware at high firing temperatures.
Feldspar is a raw material in the manufacture of glass wool and fiberglass insulation, contributing alumina and alkali flux to the glass melt used to form fibres.
Acts as a primary flux in ceramic glaze recipes, lowering the melting point and producing a smooth, glassy surface. Used extensively in tile, tableware, and decorative ceramic glazes.

What type of feldspar does Berenex supply from Egypt?
Egyptian potassium-sodium feldspar (KAlSi₃O₈·NaAlSi₃O₈) from the Eastern Desert with high alumina and high alkali (K₂O + Na₂O) content, suitable for glass manufacturing and ceramic tile production.
What is the minimum order for Egyptian feldspar?
500 metric tonnes (MT). Available in bulk vessel loading or big bags (1,000–1,250 kg FIBC). Shipped FOB Port Said or CIF to destination port.
Why is feldspar used in glass manufacturing?
Feldspar acts as a flux in glass production, reducing the melting temperature of the batch and providing alumina which improves the chemical durability, hardness, and weather resistance of the finished glass. It is typically used at 10–15% of the glass batch weight in container glass and flat glass production.
What ceramic applications use Egyptian feldspar?
Floor and wall tile bodies (the largest single market globally for feldspar), tableware and fine china (for translucency and whiteness), vitreous china sanitaryware, fiberglass insulation glass melt, and ceramic glazes where feldspar acts as the primary flux to produce a smooth glassy surface.
