Wax
I broke up the rosin (it will shatter like glass), then sliced up some bees wax. The olive oil on the ready.
Used a fuel container that you see at a cheesy buffet table.
I found a shallow skillet at the thrift shop (3 bucks)
Dropped in a chunk of rosin and held the skillet with a silicone pad (handle gets hot)
On the ready was stir sticks from a local coffee shop this morning (need caffeine at 6am)
Stir very slow to avoid splashing, I wore gloves to protect against hot splashing.
A small sheet of tin foil and a silicone cup for cupcakes (found at any bakery / craft cooking store) close at hand.
Mixed the bees wax into the rosin at about 80 to 20%
a very small amount of oil, my guess was two drops.
Set the pan aside, (don't pour the contents yet) tested what's on the stir stick.
I then dropped in a little more wax (now it's 75 to 25% or a little more)
A drop more of oil, then another drop (after testing again)
Poured the contence into the silicon cup to rest for a few minuets before introducing the freezer for five minuets or so.
Done.
A lot of trial, kinda feeling it out: one knows what your looking for in a thread wax.
This is possible the best wax I have felt in my fingers. So now this has become something I plan to make again.
