Formation from different wood species

Wood Wood and wood products, like pulp, paper, and cardboard, will burn. There is considerable variation in the heat value of different wood species and products. During combustion, wood will char. In charring, wood forms a layer of partially burned material. This layer insulates material below it from the heat of combustion and slows the burning rate. In fact, wood can retain many of its stmctural properties in a hre for some time. The stmctural properties remain because of the insulating effect of the char formation. [Pg.227]

A group of natural and synthetic dyestuffs based on the naphthoquinone structure (phenolic) have found use in the formation of lake and other pigments. Naphthoquinones are found in the leaves, blossoms, wood, bark, roots and fruit of about 20 different species. Those which are found in pigment use are AUcannin and Alkannan in AUcanet from plant species such as Alkanna lehmannii Tineo (formerly known as Alkanna tinctoria Tausch.), Macrotomia spp., Onosma spp. and juglone in Walnut qq.v.) fiom Juglans spp. [Pg.273]
