Industries
Industrial minerals Skylark Exports supplies to ceramics, glass, foundry, paint, paper, refractory, and construction plants.

Ceramics and tile
Tile, sanitaryware, and tableware plants use clay, feldspar, silica, and quartz so the body stays plastic and the fire stays predictable.

Glass
Glass batches need silica that stays high and low in iron, plus a feldspar flux whose alkali does not drift.

Foundry
Foundries buy graded silica for moulds and cores, and refractory clay where the hot face has to hold.

Paints and coatings
Coatings use ground quartz, kaolin, and calcined kaolin for mesh, brightness, and opacity in the film.

Paper
Paper coatings use kaolin for shade and smoothness, and calcined kaolin when opacity has to go further.

Refractories
Refractory and kiln-furniture bodies need fire clay with alumina and a shape that survives temperature.

Construction
Construction uses graded silica sand where grain size and cleanliness matter more than a glass-grade iron limit.

Rubber and plastics
Rubber, plastics, and cable compounds use kaolin, calcined kaolin, and quartz powder as controlled fillers.
