An investigation of time, colour and crystal, the Calortype project has grown out of research into the quantification and control of the timed release of molten glass into a mould. Colours are mixed within the hotbed of a kiln from above using a flower-pot method. The photographer Fox Talbot’s first experiments with light and Photo sensitive paper resulted in his ‘Beautiful Impression’ that was named ‘Calotype’. Using heat and glass rather than light and photography, the work has been titled, ‘Calortype’.
