Suggestion- don't use those worthless black-diamonds. Even the maroon ones have gotten very difficult to clean and yield well- maybe moreso than OGII 120s! SWIT's only ever used the black ones once and for their intended purpose...when his lighter ran dry
The free I2 in post indicates that either it never completed or there wasn't enough actual RP to recycle so to end with clearish-yellow non-cloudy sol. If it never completed from insufficient or excessively contaminated RP, expect that shortly after mixing the I2 and RP that the sol. remained dark/cloudy and stayed that way- whether it "bubbled" or not.
Did you collect anything in the filter right afterwards? Well don't assume its RP if its reddish and recycle it! If its not red even, doubt itd be RP at all or anything worth the cleaning! Did the filter collect any I2 stains with possible tarry black-silverish stuff as well? Now if that was present with red stuff, one might ask why it didn't react with the I2! That red stuffs imposter RP (or maybe coated with pill gaak but TPs assuming your sure it had nothing to do with the PFED). If it was red-maroon and with no significant amount of I2 also in the filter, was still probly mostly red glass, red paints or glues, iron oxides, and other crud. Otherwise it would've been completely used up leaving nothing but the sol. plus the free I2 that couldn't be recycled back to HI. Again, assuming the FEeD was clean.
As for the maroon ones that have the red paper wrapped, if anyone happens to have or suddenly start having bad luck with the scrapeless extractions ie IPA, HCl, blenders, etc, or filterless methods then there still is a way to end up with some usable RP without it taking that all long...
IPA and slide the maroon off...don't have to go 1-by-1, doing 3-5@once is WAY faster and can still get nearly all of it if the book ends were cut fairly flush to the strip and given a quick pre-dunk in IPA. No need to waste bottle(s) of IPA for just lets say 8-15 boxes (8-15 would only take SWIT maybe several hundred mLs)- and of course, 91% is worth using and does work better as its usually nearly as cheap as dilute 50-70%s. Cutting, well if no papercutter, still can cut 5+@once depending on the scizzors used. On the other hand, filterless and cold methods failing to yield decently or clean properly, well use the filters and boil the solvents then. Its not much harder and the mechanical losses don't seem to be that significant, esp compared with PFED. On a final note, surface area, as with PFED is very important with most red-diamonds, esp the HCl which won't do shit swirled+cold against a buncha sticky chunks...thats easily solved...
