I made some 151 proof tincture and put it in a measuring cup.
I let almost all of the alcohol evaporate.
Now i have this dark sludge at the bottom.
What types of concentrates can i make from this?
That looks about like my first concentrate extract with alcohol, though I used 190 proof. Congratulations on getting your feet wet!
What you have is a concentrate chock full of chlorophyll and water solubles, so although you can vaporize it, it will be harsh.
Orally may work, though concentrated chlorophyll gives some brothers and sisters gastic upset.
Sublingually will work, but it will taste predominately like chlorophyll (shit).
It will work topically, though will leave a green stain on your skin and a permanent stain on some clothing.
It might work in a suppository, though we've only used absolutes for that purpose, are unsure of the effects of the chlorophyll and water solubles.
I've had the best luck making pristine extracts with ethanol, by using the QWET process and 190 proof.
