The sap of another Burseraceae, Shirquillu, is used by ceramic artists to give a shiny glaze to chicha drinking bowls called macaguas. The collected sap is rolled into a waxy ball. As soon as the mucagua is taken out of the fire the ball of sap is applied to the hot surface. In contact with the heat the shirkillu melts and can be applied as a liquid to the surface of the mucagua. Covered in resin the shiny drinking bowl acquires a sweet turpentiny smell. The fruit of several Burseraceae are eaten by manyAmazonian groups.
