Mahogany is a straight grained, reddish-brown timber of three tropical hardwood species indigenous to the Americas.
The rings are of Bog Oak and Ash
Bog-wood, also known as abonos and morta, especially amongst pipe smokers, is a material from trees that have been buried in peat bogs and preserved from decay by the acidic and anaerobic bog conditions, sometimes for thousands of years. Bog-wood represents the early stages in the fossilisation of wood.
Common Ash is found across Europe, from the Arctic Circle to Turkey. It is the third most common tree in Britain.
