Getting some preliminary interesting results from ethyl acetate and want to get a work thread going here.
Ethyl acetate is cheaper than Limonene and increasingly available at hardware stores (it has
substituted MEK as a commercial solvent). As discussed in this
musing post, it can absorb some water which can make it compatible with over the counter aquarium 9.6% sulfuric acid for salting directly out of the solvent (sulfate mescaline salts are the prettiest

).
Ethyl acetate has been tested before with some positive results by for example
someblackguy.
A wet microwaved paste is used since water seems to help move mescaline into the solvent as was discussed in general in the
microwave assisted thread. Completely dried paste may work too as someblackguy mentioned.
The process shares similarities with commercial
ethyl acetate coffee decaffeination: steam is used and water is present to help diffuse the free base alkaloid into ethyl acetate.
Steps:
1) Make a Ca(OH)2 and NaCl microwaved cacti steam paste. Details in spoiler.
2) Pull with ethyl acetate (first picture). This is not dried over MgSO4 since it should only contain ~1.9% water, and be able to absorb up to 3.4% water during neutralization. Avoid whipping into a souffle, slow stirring and diffusion time works best (in the coffee process, diffusion/time is sufficient).
3) To help with the next step (neutralization), a few drops of ethyl acetate tumeric extract ate added. This changes the color from yellow to orange (second picture).
4) Neutralize with 10% sulfuric acid, one drop at a time and making mixing well (water should be absorbed into the ethyl acetate). When neautralized, the orange color from the tumeric curcuming extract dissapears and "glitter" starts to form. This glitter is a mescaline sulfate candidate (3rd picture).
5) Next (ongoing) will be to collect/clean precipitate and test it (bioassay, analysis, etc).
The process is straight forward and simple
