OK,swim does add one step prior to freeze precip.
Once the naptha is all extracted, is left to sit for an hour or so.. making judgements on time as it goes..
Swim finds unwanted particles will fall to the bottom in this stage.
Then pouring the sol into another clean airtight vessel making sure the residue is left behind.Swim may lose a little active sol as a result, but you gotta break a few eggs when your baking a cake such as this
Then in the freezer with the new batch for 24 hours or until sol is clear.
Freezer is fan forced as well.
After this-
Take out, and run cold H20 over top of jar, then dried and opened.
H20 helps break the seal easier, just be sure to dry immediately after.
Sol is poured away and lid put back on quickly,before any condensation hits inside.
Jar upside down for about an hour, then remove lid and place on side to dry for another 2 hours.
Swim then gets spoon and scrapes out xtals and places into 30-50ml shotglass and paper towel cover applied..or you can just put it under an kitchen exhaust fan.
