Leadwood - Prosono international

This wood was initially introduced to our American distributor then followed to our UK distributor and finally got wider acceptance.
Leadwood has found acceptance for narrow applications like knife handles, smoking pipes and to a limited extend for guitar back and sides and bagpipes.
As this wood turns well, has a fine grain and provides a glossy finish application like salad bowls and ornaments have become popular.

Heartwood

The wood ranges from grey to darkish black. Sapwood is distinctively yellow. The wood is very hard and heavy and of limited porosity.

Saw milling characteristics

The wood is hard and therefore cut in stages. In a first stage, the logs are broken down in slabs on a band saw with a flexible thin blade. In a second stage, into parts with tungsten tipped blades. As silica is often present, leadwood blunts tools quickly.

Seasoning

It dries fairly-well and quickly to 1.2 t per m3 which is high and explains its acceptance for musical instruments like guitar back and sides and bagpipes.
