Apricot Fire Wood

The best firewood to use to make lye comes from ashes of hardwood trees, preferably fruit woods.  Firewood can be difficult to procure sometimes. Craigslist is a great place to find free firewood. Harder wood burns hotter creating good white ash.

Here are some other types of hardwood:

Ash

Aspen

Birch

Cherry

Elm

Hazel

Linden/Lime/Basswood

Mahogany

Maple

Oak

Teak

Walnut
