A Hollow Form made from Horse Chestnut Burl. Approximately, it stands 18.7cm tall at it's highest point and the widest diameter is 15.7cm. The opening is 4.3cm and the base is 9cm in diameter.
You can see it being made here on my YouTube channel:
The pieces I make are decorative/ornamental and are not waterproof or food safe.
Wood is a natural product - I cannot guarantee that there won't be further movement over time or depending on the environment it is in, to me this can enhance the piece, but I understand not everybody will like this.
