- ‘Recent experiments suggest that sulphuring an inverted barrel but not bunging up results in a much lower level of volatile acids since bunging up creates a humid environment, ideal for the growth of bacteria.’

- ‘Fruits may be pretreated by sulfuring, salt solution, ascorbic acid solution, or steam blanching.’
The traditional British spelling is sulphur and the US spelling is sulfur. In chemistry and other technical uses, however, the -f- spelling is now the standard form for this and related words in British as well as US contexts, and is increasingly used in general contexts as well
Middle English: from Anglo-Norman French sulfre, from Latin sulfur, sulphur.
