$50 is a really good deal. I would want to use a prepress though. I'll show some pics in a bit but I use a prepress, no bags, and generic everyday kitchen parchment paper.
I prepress my pucks, I think I usually keep it around 7 grams a piece up to 14 grams at a time. I will now do two pucks if I go much above 9 grams as I seem to have better return.
Then I just scrap the rosin up and put it on a silicone mat for shaping or in a little silicone container for storage.
Press at 190 degrees F for about 3 to 4 minutes but I'm really not too scientific. I usually stop when it seems to stop flowing.
Rosin is vaped in my dab pen or slathered on the best joints ever. Pucks are currently used for oil but I know people make tinctures or repress a bunch of them for more rosin.
The demo idea is great!
