A beautiful handblown wine glass made in an unusual blue tone, designed to deliver some colour. Mineral Blue is taken from Blue John (also known as Derbyshire Spar) a semi- precious mineral, a form of fluorite with bands of a purple-blue.Lighter and finer, they echo the shape of our tumblers, also inspired by 17th Century British glassware shapes. Mix and match with our jugs and carafes and set the table with our artisan-made glassware.
