How to make your own tincture from shatter?

I often make FECO (evaporated tincture) then dilute with oil, because oil tincture is easier on the tongue, and can be put into capsules without melting them.
So you can use either alcohol or any oil to make tincture.
Here's a recipe for 5 g concentrate that will produce an oil tincture of about 2 mg thc per drop in a 1 oz tincture bottle:
1. Decarb @ 240 F for 40 min using a verifying thermometer.
2. Add 18 g oil and 5 g lecithin.
3. Bake mixture @ 220 F for 20-60 min. 60 min is slightly sleepier than 20 min.
4 Put into a tincture dropper bottle.

If the concentrate were 40% thc, then
THC = 0.4*5000 mg = 2000 mg
Concentration = (2000 mg thc)/(30 mL) = 67 mg thc/mL.
1 drop ~ 67 mg thc/30 = 2.2 mg thc
If potency is 80% then double the above result.

If you prefer an alcohol tincture, follow step 1, then add enough alcohol to fill a tincture bottle.

I own 2 Magical Butter Machines, and 1 Infusium420 to make tinctures and oils.
Infusium is my preference.

Also the Ardent Nova/Lift makes decarb very easy, but it is expensive.

 

This is the way I do it. You can use the oven, too.
