Resinous sap, from a buyū'an or ulittāgu tree.
Cracks in a water pot, pannūman, or wine jar, tibung, are repaired by heating the cracked area. Hot resin is poured in to seal the cracks. Also used to glaze clay pots, see duwin. The sap is secured by slashing oblique cuts in the tree trunk. Six months to a year is required for the sap to ooze and harden on the trunk.
