Contact AurumLeaf

AurumLeaf is a small, independent, ad-supported site — there is no support team standing by, but a real person reads what comes in to support@aurumxchange.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the leaf sheet coverage calculator, size dry-time calculator, karat & color guide, gilding cost calculator, book-of-leaf quantity calculator, or leaf thickness calculator — and what you entered); a tool or technique you wish existed on the site; an out-of-date fact or broken link in the blog, learn section, or the Gilding Museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If a question is really about a specific leaf product, adhesive, or substrate, the manufacturer or your supplier will have a more authoritative answer than this site can give; AurumLeaf’s tools produce general estimates, not lab-certified figures, and the site isn’t affiliated with any leaf manufacturer or supplier.

Before writing in about a tool result, it can help to double-check the numbers you entered — area, sheet size, waste percentage, or room temperature are the most common source of a surprising answer. If it still looks wrong after that, that’s exactly the kind of message worth sending.
