Wallace Seymour Burnt Sienna, Monte Amiata Bespoke Oil Paint
Burnt Sienna, washed. Bagnoli, Monte Amiata PBr7
When raw sienna is calcined (heated) in a closed furnace or kiln, it changes shade to give a fiery-red colour. This calcining process also creates a slightly more transparent effect (compared to raw sienna) when the resultant paint paste is applied as a glaze.
The original pigment from Monte Amiata is now exhausted: Wallace Seymnour take their Raw Sienna, Bagnoli and calcine to 320C to re-create the original shade. It has unsurpassed transparency and a bright fiery-red under shade. Totally unique.
