Ash can be differentiated from hickory (pecan) which it also resembles, by white dots in the darker summerwood which can be seen with the naked eye. Ash burls have a twisted, interwoven figure. Uses: Ash is widely used for structural frames and steam bent furniture pieces.
Birch wood is always a light shade, but the color varies depending on the species. White birch wood is light with a brown flame pattern near the center, yellow birch wood is light golden brown, and red birch wood looks similar to white birch but with a light red tint.
Wood lacquer is the best choice for any interior dark-stained cedar. It can be sprayed or brushed on. Lacquer dries quickly, making it the most efficient of all the available coatings, but cannot be used for exterior cedar. The lacquer formula is thinner than other coatings, and will penetrate faster.
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure. MDF is generally denser than plywood.
Redwood lumber is very soft and lightweight, with a decent strength-to-weight ratio. It is also exceptionally stable, with very little shrinkage or seasonal movement. The mechanical values listed at the top of the page represent the averages between both old-growth lumber and second-growth lumber.
