Step 1: Gather Your Materials
A few other things you will need are:
-Powdered Charcoal. When you get your resin/rosin to a pure form it will be very brittle and will not be an affective adhesive. The charcoal will give the mixture strength. I grinded up some excess charcoal from a recent bonfire. If you don't have access to charcoal you can always use beeswax.
-A few pots. You will need at least two pots. One will be for the initial melting of the resin/rosin, and the other will be for mixing in the charcoal.
-A jelly/jam jar. When the glue is done you will need something to store it in. An extra jelly jar worked great because the glue can be reheated in it.
-A filter. The actual product doesn't matter, just something with a small metal mesh that can filter out everything non-resin/rosin. Traditionally, Native Americans would place the resin/rosin in a woven bag. The bag would then be placed in boiling water; the resin would seep out and float to the top of the water, while the impurities would stay in the bag. I did not have access to one of these bags, nor did I want to make one, so I just used a small filter which did the job.
-*OPTIONAL* Some aluminum foil. The whole process can be messy, so aluminum foil protects your stove and kitchen.
-*OPTIONAL* Something to stir with. Though stirring isn't needed, it can help in the process.
