The Mathmos Thaw is an ice candle, no….not a candle made of ice, but a candle surrounded by ice. Intrigued? read on! The base acts as a a mould, simply fill it with water as per the instructions, pop it in the freezer overnight and the the next morning you have a hollow ice cylinder to place onto the base. All you need to do now is light a tea candle in the middle and watch as the ice slowly melts away (don’t worry, the water accumulates in the base) giving any room a ‘cool’ glacial glow as well as a interesting centrepiece.
