EVAPORATOR

Cut a couple of holes in the mason jar lid as close to the size of the 1/4" pipe/hose barbs as you can get them. Ideally, you should be able to thread the barbs into the lid and snug them up. Then puth the lid on the jar upside down and screw the ring on snug, but not too tight.

Solder the joint of the lid and barbs from the bottom.

Set it aside and move on to "extraction chamber."
