Turkish pumice stone for denim washing
Screened, washed and size-graded pumice for stone wash, enzyme wash and vintage effects. Full containers to denim mills and laundries worldwide.
Origin · Anatolia
Born in a volcano
Pumice forms when gas-rich lava cools in seconds. Thousands of trapped bubbles make it light enough to float, and give it its grinding edge.
Specific gravity 0.5–0.9 g/cm³SiO₂ 68–72 %
Inside the washing drum
Every pore is a tiny abrasive
As the drum turns, the stone rubs indigo off the surface of the yarn. The white cotton core shows through and the fabric fades evenly.
The result
The classic stonewash, lot after lot
Graded sizes and low dust give laundries the same shade from the first container to the hundredth.

Why quality matters
Cheap pumice is expensive
Stones that crumble turn into sludge. Sludge clogs machines, dulls the shade and spoils lots. You pay twice: once for the stone, once for the rework.
Zenstone pumice is screened, washed and graded before it is bagged, so every bag behaves like the last one.
Poorly graded pumice
- Crumbles in the drum
- Leaves dust and sludge
- Mixed sizes, uneven shade
Zenstone pumice
- Holds its shape through more cycles
- Washed before bagging
- One size range in every bag
Why our pumice
Even on the fabric, gentle on the machine
The quality difference shows in hardness, breakage rate and dust.
Hardness
Long-lasting stone
Selected from high-strength deposits, it lasts more wash cycles and lowers your cost per kilo of garments.
Cleanliness
Low dust and sludge
Washed and screened before bagging, so there is less sludge, cleaner machines and easier rinsing.
Grading
Uniform size
The same size range in every bag gives consistent wash results from lot to lot.
Supply
Reliable supply
Year-round container loading backed by our own stock and port connections.
