131 Tamo Ash

Tamo Ash is Harvested Specifically for its Peanut Figure

This week I feature the Tamo Ash, Fraxinus mandshurica. It is a species of Ash primarily sought for the unique "peanut" figure. Like a lot of figured woods it is not totally understood how the figure is formed but proper use of the whole tree must be considered for the health of the species.

Also I talk about ray fleck in White Oak, trees vs shrubs and drying wood. Is there an ideal environment for drying and preventing bugs in your woods?

Featured Species: Tamo Ash

Fraxinus mandshurica or Tamo Ash or Japanese Ash or Manchurian Ash is like most Ash species.  Probably nearly identical to Black Ash.  But when it exhibits a distinct "peanut" figure we call it Tamo Ash.  The market for this species is entirely in veneer and you won't find actual boards with that figure.  This has caused some harvesting issues and now those who harvest the tree are ensuring that the unfigured woods get used as well and not left on the forest floor.  Because of some of these past bad practices, Tamo Ash is CITES appendix III listed in the Russian Federation. 

From a technical perspective it is just like Black Ash from hardness and workability.  But in many ways these numbers or moot since it will only be found in veneer form.
