The Josi Mug is a mug designed to warm up the user’s hands using the hot beverage inside as a heat source. This is done with ergonomically designed finger holes that protrude into the mug cavity. The ceramic body of the mug is slipcast with a specially designed mould to overcome the difficulties of producing overhangs with the slip casting technique. A silicone sleeve protect the user’s hand from being burnt by excess heat and also adds a nice design feature.
Josi Mug has just started a crowd funding campaign on Indiegogo see http://www.indiegogo.com/JosiMug.
