English walnut trees can be tapped successfully, especially when subjected to a freezing winter and spring. Paper birch (Betula papyrifera) The paper birch has a lower sugar content than sugar maple (less than 1%), but is the sweetest of the birch trees.
A caustic, toxic sap, called urushiol, is tapped from the trunk of the Chinese lacquer tree to produce lacquer. This is done by cutting 5 to 10 horizontal lines on the trunk of a 10-year-old tree, and then collecting the greyish yellow sap that exudes.The sap is then filtered, heat-treated, or coloured before applying onto a base material that is to be lacquered.ther common names include Japanese lacquer tree, Japanese Sumac, and varnish tree. The trees are cultivated and tapped for their toxic sap, which is used as a highly durable lacquer to make Chinese, Japanese, and Korean lacquerware.
