What is it?

Why does it matter?
Pumice is why some concrete blocks are light enough to lift one-handed, and why stonewashed denim looks the way it does.

“Withheld” means the USGS suppressed the figure to avoid disclosing an individual company's data — it does not mean zero. Country rows do not always sum to the world total because the source rounds each figure independently and does not always break out an “other countries” line.
