Industrial Commodity
Purified feldspar for glass and ceramics
NAGTAR sources purified feldspar against glass or ceramic chemistry — not as an undifferentiated industrial sand.

What is Feldspar?
Feldspar is an alkali aluminosilicate used as a flux in glass and ceramics. Iron, alumina and alkali content decide whether a lot fits the batch.
US market focus
US glass and ceramic plants import feldspar when alkali and iron windows are hard to fill domestically. We qualify chemistry before freight into US ports.

How we source Feldspar
Send the glass or ceramic use, chemistry window, size, volume and destination.
Supply continuity
Algeria-first feldspar with multi-country backup so glass and ceramic programmes keep alkali windows when one quarry or plant pauses.
Trade and market context
Feldspar imports follow glass and ceramic chemistry needs. USGS/USITC for context; broker for HTS.
