Burnt ash is thermally modified White Ash which is grown in North America and the Balkans. The thermal modification is the most natural, chemical free and sustainable method of wood preservation which enables wood to withstand and resist all weather conditions and minimises maintenance. The thermal modification process darkens the white ash into rich medium to dark chocolate colour.
Thermal Modification is a process that replaces the use of chemicals to enhance an inapt wood species performance with heat and steam so it is suitable for a multitude of applications indoors and out. The high heat modifies the cell structure of the wood and makes it highly resistant to rot while greatly reducing expansion and contraction.
