Wood-dust concentrations vary with type of dust extraction, amount of wood removed, and type of sander (Thorpe and Brown 1994). [2] For electric belt sanders used to sand dowels , total dust concentrations ranged from 0.22 mg/m with external dust extraction to 3.74 mg/m without extraction, and concentrations of respirable dust ranged from 0.003 ...

The color of the ash comes from small proportions of inorganic minerals such as iron oxides and manganese. The oxidized metal elements that constitute wood ash are mostly considered alkaline. For example, ash collected from wood boilers is composed of [6] 17–33% calcium in the form of calcium oxide (CaO)
Elaborate nickel and chrome edged models took designs to the edge, with cast ornaments, feet and doors. Wood or coal could be burnt in the stoves and thus they were popular for over one hundred years. The action of the fire, combined with the causticity of the ash, ensured that the stove would eventually disintegrate or crack over time.
