American Roasted White Ash

ITI NZ

In general ash is a light-coloured wood, with sapwood varying from white to yellow and heartwood light to dark brown, sometimes with lighter streaks. The colour difference between the outer light-coloured white sapwood and inner, darker, even brown heartwood is quite distinct. Ashwood is generally straight-grained with a coarse uniform texture. Its appearance has a very strong grain contrast between the softer summer growth and hard winter growth rings. No two pieces are ever the same in appearance. 

Light brown flecks, or mineral streaks, sometimes referred to as ‘glassworm’, are common in ash and are treated as a natural characteristic, and are not considered as a defect under the NHLA Grading Rules. They do not undermine the integrity of the wood.
