It is literally the first google result when you search for "kiln", even above the original definition of the term.

Think you are getting personalized search, it's #2 if not logged in to Google.

Hrm. Might be regional? Or tied to user agent? If I search in incognito mode it's still #1 but it's #2 via lynx from two different VPSes.

It's geo-based, it seems. It's #1 when not logged in, in the UK; it's #2 (with Wikipedia #1) when coming from the US.

It's also the first result in DDG, fwiw.
