Grain: Interlocked and sometimes wavy. Texture fairly fine.

Colour: A medium to dark reddish-brown wood typically with a well-marked stripe or roe figure which shows to advantage on accurately quarter-cut veneers. Occasionally logs with wavy grain yield veneers with a highly decorative fiddle-back figure. 

European Oak (Quercus Robur)

Category: Hardwood

Region / Grown: France, Germany, Austria and the Balkan states.

Use: European oak is a dense very durable hardwood used for external joinery, front entrance doors and screens, French doors, panelling, gates and windows.

The combination of durability and decorative appearance is valuable. 

Grain: Straight grain with a medium to course texture. Quarter-sawn material has a characteristic ornamental silver grain due to the broad rays. Structure and quality vary widely according to the conditions of growth. Oak from central European countries is often of slow, even growth, uniform colour and straight grain, while that from northern countries is characteristically harder and tougher.

Colour: Light in colour

Drying: European oak dries very slowly.

American White Oak (Quercus Alba)

Category: Hardwood

Region / Grown: Eastern half of the United States and south-eastern Canada

Use:  Mainly used for internal projects such as stairs, handrails, furniture and flooring. Another dense oak not as durable as European, therefore not recommended for external use. Used as veneer for internal furniture and cabinetry. Selection can provide a quarter cut contemporary straight grain veneer and more decorative flowery crown cut veneer. Machines well and has medium movement. 

Grain: Generally straight. Quarter-sawn material has a characteristic ornamental silver grain due to the broad rays. Structure and quality vary widely according to the conditions of growth. Oak from the Northern Appalachian area are usually slow grown producing a comparatively lightweight, mild type of wood.

Colour: Varies from pale yellow brown to mid-brown.

Drying: American white oak dries very slowly. 

Douglas Fir (Pseudotsuga Menziesii)

Category: Softwood

Region / Grown: North America, British Columbia
