What kind of bark/material did you use?
Was the evaporation done before you put the jar in the freezer?
Was the jar sealed when you put it in the freezer?
How many grams of bark/material did you use? What was the total volume of your pulls?
You may need to evap the naphtha further, using a safe method from the Health & Safety.
Quote:NEVER evaporate or warm up a flammable solvent next to a fire source or equipment that might generate sparks. For warming up solvents, boil some water separately, turn off the fire/heat source and only then add the solvent to a container and submerge the bottom of the container in the recently warmed water. Have the container with the warming-up solvent opened or with a very loose top, otherwise pressure might be generated and it can explode
Also, in the future, it helps to ask questions in a specific way to get helpful responses. Check out
