Melting pine or fir resin without a metal container?

You could have him mail you some.

I use spruce pitch. Never really used pine pitch although I have some refined rosin in different grades.

Then he'd say......"Say WHAT?, you want me to mail some what?.....That sticky nasty stuff?....You Yankees are nuts...."....LOL

I’ve come to believe that it’s an art form getting it just right. You usually end up with sap that cures to soft or to brittle. Most igneous rock holds heat well. Basalt is easy to find here because the unconformity in the rock layers are right to the surface.

I've seen people 'stab' a ball of pine resin with a stick and heated up over a fire, and proceeded to use as a glue stick to fix an assortment of leaks. No container used at all but definitely specific to that particular method. The previously mentioned muscle shell idea is perfect from a strictly primitive standpoint.

In Europe, in prehistoric times, they never made glue out of resin, they always used tar instead. Strange, we have plenty of pine and spruce.
With a friend I did some experiments making birch tar without using pottery or tin cans. It workt.
