MESOLITHIC RESOURCE GROUP
Birch bark tar experiment underway.
We are pleased to announce that we successfully produced birch bark tar using only sand, birch bark and fire, in our last round of experiments in October 2013.
These experiments focussed on the use of raised structures, which showed promise in our previous experiments of 2009.
The basic materials for tar extraction: Sand and birch bark.
