You could need a metal spout and a ceramic bowl, after preparing the trunk with an axe you could add a couple of spouts and bowls and in the course of two or three days you would get resin. It would save you from looking for resin like a maniac on every pine trunk.

To add depth, overexploiting a tree could kill it / reduce yield and maybe this could be only done in summer, the bowls could gret dirty much like the pots with wax
