It is also known as pokerwork or wood burning. [1]
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...

The density of dry balsa wood ranges from 40 to 475 kg/m 3, with a typical density around 160 kg/m 3. [5] [6] [7] Balsa is the softest wood ever measured using the Janka hardness test (22 to 167 lbf). [8] The wood of the living tree has large cells that are filled with water. This gives the wood a spongy texture.
How We Tested the Best Bamboo Sheets. First, I rounded up a list of the top-reviewed bamboo sheets on the market. Then, I made sure each editor slept on the sheets for 30+ days—and washed/dried ...

Pine: Pinus spp. Pine wood is hard and tough except white pine which is soft. It decays easily if it comes into contact with soil. It is heavy and coarse grained.
By the 1790s most of the viable stocks of mahogany in Jamaica had been cut, and the market was divided between two principal sources or types of mahogany. Honduras mahogany was relatively cheap, plentiful, but rarely of the best quality. Hispaniola (also called Spanish or Santo Domingo) mahogany was the wood of choice for high quality work.
