UK: Superglass has tested a glass wool tea cosy against a traditional woollen version in a promotional video broadcast live on social media. In the experiment the tea cosy, made of 84% recycled glass wool insulation, kept a teapot hotter over a 90-minute period than an identical teapot with a woollen one. The teapots were filled with identical volumes of water and were measured with identical thermometers. By the end of the 90-minute experiment, the Superglass pot registered 67.7°C and the traditional cosy was down to 55.0°C.
“Of course, the tea cosy video is a bit of fun, but it highlights just how much of a difference good insulation can make,” said Bob Dalrymple, Head of Marketing at Superglass. He added that the company does not intend on manufacture tea cosies for sale.
