CIELO

Introduction

CIELO stands for Crystals In Ethyl-acetate Leisurely OTC (Over The Counter).


In this TEK, aqueous lime cactus paste is broken down by microwave radiation, saturated with CaCl2, and extracted with ethyl acetate. The extract is chemically dried and salted with citric acid to precipitate mescaline citrate crystals.


Processing the paste in the microwave to make it ready for extraction is the most laborious part of this TEK. There is also a MgSO4 chemichal dry that may need some user practice to perform cleanly.

Materials

  • Quart jars with lids*
  • Food scale
  • 25g Ca(OH)2 (lime)
  • 300g water
  • 100g powdered dry cacti
  • Microwave
  • 130g + 20g anhydrous CaCl2
  • ~ 1000g Ethyl acetate ("MEK substitute")
  • Citric acid
  • pH paper (optional)


*If lids are plastic, use ethyl acetate resistant LDPE or PP.

Safety

Review ethyl acetate's safety information[1] and check the manufacture's MSDS to verify you have pure ethyl acetate.


Do not microwave a sealed container. There must be a ventilation path for water vapor to avoid pressure buildup and a cracked jar or explosion.


Microwaving lime cacti paste produces in smelly ans will be noticed by the people in your surroundings. Lime is a skin irritant and hot lime will be more severe, avoid skin contact.


These are only good-faith suggestions. They do not guarantee safety. Each adult individual needs to review external information throughly and make their personal decision on proceeding.

Process

Paste

Mix lime, water, and cactus powder to a homogeneous paste in a canning quart jar. Keep on mixing for few minutes until the paste goes from clumpy to smooth (~10 minutes).


Microwave paste between 300W and 500W in bursts of 5 minutes or less monitoring closely (it easily boils over). Paste will liquefy after about 30g of water evaporate. Continue microwaving until a total of 50g of water evaporate. Total microwave time is ~30 minutes.


Allow to cool and mix in anhydrous CaCl2 slowly (dissolution is exothermic) stiffening the paste. The ideal final paste is stiff and not hard to stir. Plant matter can vary, so adjust CaCl2 ammount if needed to get to the right consistency

Pull

Add ~ 300g of ethyl acetate to the paste making the jar ~3/4 full. Stir slowly and thoroughly. Cover with lid and let it sit for a few hours or more**.


Decant solvent into a second jar. About ~100g of solvent will remain in the paste.


Pull three more times with ~200g of ethyl acetate, making the jar ~3/4 full again. Decant into the same jar as the first pull. The paste may become sandy or change in later pulls**.


Combined pulls will give ~a quart of clear yellow extract. Optionally, more pulls can be done later for a modest yield improvement.


**Troubleshooting:

  • If solvent separation is poor the paste is too wet. Add CaCl2 to fix.
  • If paste in hard to mix with the the paste is too dry. Add water to fix.

Dry

Dry combined extracts extracts with 15g of anhydrous CaCl2[2]. Decant clear solution to new jar.


Note error.png Note: Is this step really needed? How much CaCl2 is really needed.

Salt

Gently drop ~250mg (~1/16 tsp) of citric acid into the extract without stirring***. Clouds form as the citric acid diffuses into solution reacting with free base mescaline. After a few hours at room temperature the clouds settle as beautiful mescaline citrate xtals. If xtals have difficulty forming, move dish to fridge, and if that still does not work, the freezer. The need for cold temperature indicates an issue with the process such as incomplete microwave breakdown or poor chemichal dry. If xtals do not form even in the freezer, there is a more serious issue with the process or materials. It should still be possible to recover any product in the solvent with water pulls as is done in other TEKs (to finish, evaporate water and wash resulting residue with anhydrous ethyl acetate).


Every 10mg of citric acid (CitH3) reacts with enough free base mescaline (Mes) to precipitate up to 43mg of mescaline citrate:


3Mes(↑) + CitH3(↑) ⇒ 3(MesH)Cit(↓)


Salting is complete if no clouds form after adding more citric acid (e.g. ~ 50mg), or optionally if pH paper is neutral/acidic. A few hundred mg of citric acid should be more than enough for the typical cactus (0.5% to 0.8% yield). The legendary Ogun would need 1000mg of citric acid for 4.3% yield.


Over acidifying is not a big concern. There is room for a lot of excess citric acid in solution since several grams can dissolve in a quart of ethyl acetate.


***Stirring won't cause any major issues. Crystals will be smaller and firm sooner - which some entities prefer.


Note error.png Note: The microwave break down of plant matter and a good chemmical dry both seem to help get good quality xtalization at room temp. However, even when those steps are not done (or not done well), xtalization can be forced in the freezer (usually). Perhaps this could even enable skipping the microwave step and/or the drying step someday - especially if CaCl2 gives a drier solution while pulling (compared to NaCl).


Note error.png Note: Other organic acids could work. Perhaps an anhydrous one could be better (citric acid is monohydrate)? Tested fumaric and got wispy xtals (not ideal). Malic would be interesting (natural mescaline salt form?). There are many other solid organic acids soluble in ethyl acetate.

Finish

Pour off ethyl acetate into a storage container**** leaving the crystals behind (if needed, a filter can help catch any that accidentally pour out). Rinse xtals with fresh anhydrous ethyl acetate (dried over CaCl2) at least once and until yellow color is removed to personal cosmetic satisfaction. Leave xtals uncovered to evaporate all residual solvent, this is the final product. Optionally, the product can be dissolved in minimal warm water and slowly evaporated undisturbed to obtain long crystal needles.


Mass spectrometry results indicate the product is very clean mescaline (see image below from a sample with rinses that still had some off-white coloring).

Yields are highly dependent on starting cacti powder. They can vary from 0.1% to 5% (0.5% to 1% being common).

****Solvent can be washed with brine and reused.
