As far as I can find, no-one has actually made a International Standard Cup of Tea – ISO 3103 or BS 6008 – for the internet before. Lots of people have talked about it, but that’s easy. Making one? That requires precision… and some specialist equipment.

Thanks to Morag Hickman for letting me borrow her workshop for last-minute filming! She makes beautiful jewellery, like ring-keepers, dragon necklaces and rings that looks like ocean waves: https://etsy.com/shop/Errant
Update: someone has found an earlier ISO cup of tea on the internet, as part of a German video on tea tasting: https://www.youtube.com/watch?v=utwwkNkNgiM
