Step 3: Making hash rosin cartridges
To make the hash rosin carts I will use a toaster oven and a small jar. I will also use a glass syringe, and some SPRK ceramic cartridges.
First I put about 10 grams of hash rosin in a sealable jar.
Next I put the jar with the rosin and the lid in the freezer for about an hour to get everything cold. Then I put on the lid and removed it from the freezer. I don’t know if this step is necessary, but it is a tip I picked up when reading about making solvent-less diamonds. The idea is to increase the pressure in the jar.
Then I heat the toaster oven to 150*F and allow the jar to return to room temperature. I place the jar in the toaster oven for 24-48 hours.
About 24 hours later, the rosin has melted, but still has some bubbles forming. It’s not quite ready yet.
About 48 hours later, the rosin is clear and no longer has any bubbles. Now remove it from the toaster oven and allow it to return to room temperature.
Once the rosin has cooled to room temperature, transfer it from the jar to a glass syringe for storage. Pouring the rosin into the syringe works a lot better than trying to suck up the rosin. My Glob Father is a very handy tool for this purpose. Gently heating the glass syringe with a torch can also help get things flowing.
Finally, I use a 14 gauge blunt tip on the syringe to fill the cartridge. Once filled, heat the toaster oven to 100*F and let the cartridges wick for about 30 minutes.
Top off with more rosin as necessary. I like the PCKT SPRK ceramic cartridges, I found I can re-fill them about three times before I need to replace them. When re-filling them, you don’t need to let the cartridges wick.
