Pumice is a lightweight, porous volcanic rock used in denim stonewashing, horticulture, landscaping and filtration. The right grade depends on how you plan to use it.
Available size grades
A2Z supplies Indonesian pumice in five grades: 1–3 mm, 3–6 mm, 6–10 mm, 10–20 mm and 30–50 mm.
For denim stonewashing, trial a sample with your fabric and wash process to check the effect. For horticulture or filtration, specify the particle size your growing mix or system requires.
