I've just concluded a little experiment, three extractions on the same San Pedro powder, and I seem to have a similar result to Cheelin: non-microwaved 69ron paste had significantly higher yield. In addition, the non-micorwaved contained 0 yellow coloring in my evporated material.

However I am a noob, these are my first extractions, so it is likely I am not controlling all my variables particularly well. So please take this with a grain of salt. I'm getting some more cactus soon and will retry the experiment.

Extraction #1: Microwaved, Chilled EA with 1 minute pulls, fast crystallization 15mg/g: 0.180g mesc citr / 39g cactus powder == 0.46% yield

Extraction #2: Microwaved, Chilled EA with 3 minute pulls, slow crystallization 5mg/g: 0.244g mesc citr / 40.5g cactus powder == 0.60% yield

Extraction #3: NOT microwaved, Chilled EA with 3 minute pulls, slow crystallization 5mg/g: 0.361g mesc citr / 40.5g cactus powder == 0.89% yield

So I got a pretty significant boost in yield with not microwaving, about double in my case.

In addition, the non-microwaved experiment CONTAINED 0 YELLOW COLORING. I was very happy about this. For #1 and #2, I only get the white crystals in my filter; the evaporated stuff always contains some kind of yellow coloring and was kind of stickyish. But for #3, both the filter and the evaporated stuff had no yellow coloring. This was really cool.
