Slanted strip of thick bark are cut from the tree. The thickness of the tree determines both the flow of latex and the amount of damage done to the tree. Precise skill are necessary in order to successfully tap a tree. A liquid concentrate is formed from 10% of all the collected latex by removing water from the sap, and thereby increasing the rubber content up to 60% Acid is added to the liquid concentrate in order to produce solid sheet of dry rubber.
