Fact-Checking & Sources Policy

We use sources according to the claim they can support. For occupational hazards and dust controls, we prioritize U.S. sources such as NIOSH and OSHA because the site primarily serves U.S. readers. NIOSH research and OSHA guidance inform risk and control discussions; workplace regulations do not automatically apply to every hobbyist at home. Canadian or other guidance may be used when it adds relevant material-specific detail, with its jurisdiction made clear. For a particular tool's safe use, the manufacturer's current instructions matter. For stone identity and properties, credible geological or material sources and information about the actual supplied block are important. For carving technique, established specialist instructors, clubs and documented workshop guidance can be useful.

A retailer's tutorial may explain its own kit well, but it does not establish universal safety for all materials. Forum experience can reveal a real question without proving the answer. Marketing claims are not treated as independent tests. We link to source material near claims that need it and explain uncertainty when sources or stone varieties disagree.

We review links and claims when a guide is substantively updated. The editorial policy explains how research differs from first-hand experience and how meaningful updates are dated.
