In 2010 I was invited by the Sylva Foundation to become a partner in the OneOak Project. As a spoon carver I therefore felt obliged to make some spoons from the OneOak tree despite the fact that oak is not normally used for such pieces.
From Richard Mabey's book Food for Free and Wild Food by Roger Phillips I was aware that the Native Americans used acorns as a foodstuff. Although high in tannin which causes a bitter taste, they solved this by washing them with large amounts of water. In addition, Gwyndaf Breese describes in his book Traditional Spooncarving in Wales how in the past some spoon carvers boiled their spoons.
Based on this I decided to boil the oak spoons that I had made as part of the OneOak Project.
Due to the release of tannic acid I used a stainless steel preserving pan for the boiling.
The spoons were boiled for about one hour with three or four changes of water. This produces an evil looking "spoon soup" as shown.

At this point I was concerned that I had just ruined a lot of spoons and produced a pile of dull brown kindling.
The spoons were left for about two weeks to dry before I tried to finish them.
During this time I recalled that historically oak bark had been used in the tanning industry. It therefore appeared that I had unintentionally "tanned" the spoons!
After two weeks drying the spoons had become lighter in colour but retained a flat dull appearance.
The first few spoons were sanded by hand and then oiled using food grade linseed oil. This resulted in an attractive "antique" oak appearance.
One of the earliest spoons I made from the OneOak tree was one for Norman D. Stevens' "Gathering of Spoons" collection.
Other spoons were finished in a variety of ways including (from left to right):
