"Having a purity of 99% or greater." Needs to be verified in this specific sense, as distinct from just "very refined". Equinox ◑ 18:02, 14 December 2017 (UTC)
- I am finding percentage cutoffs everywhere from 99.9% to 60% for the use of the term "ultrarefined", depending on what the text is talking about. Even if we do find three that are talking about 99%, I think the definition would be misleading, because it implies something more universal - if we wanted to go down that route, it would involve giving the cutoffs for different substances, and I don't think we want to be that encyclopedic.

- This is clearly a case where, at best, ordinal ranking of the various brackets of purity would be fit for a more or less universal definition (eg, pure > ultra-refined > ? > ? > raw/crude). It seems to me that a usage note might be the best we can do, if we even have facts to support such a note. A search for “*refined”, in OneLook Dictionary Search. doesn't generate any such terms, using refined other than ultra-refined, refined, and unrefined. DCDuring (talk) 22:33, 18 December 2017 (UTC)
