Ethyl ether continuous leaching method replaces the water contained in bamboo tube. Before the ether volatilizes, the bamboo tube is soaked in the solution of mastic gum or dam fat dissolved in ether, and taken out after the resin permeates the bamboo tissue, so that the ether volatilizes, the resin in the bamboo can be preserved, and the bamboo apparatus can be strengthened. The bamboo and wood products reinforced by this method not only have beautiful color, no shrinkage deformation and no cracking, but also can shape the cracking deformation.
