Okay, here I will describe exactly what I did. (also I bought from a source which has multiple reports of a 2% yield when extracted properly)
I got my pre ground up bark, added it to my 1000ml erlenmeyer flask. Then I added 500ml of distilled water, then I added another 200ml of distilled water with about 50g of lye in it mixed in slowly bit by bit, it turned black and everything appeared how it should be. I wrapped the top of the flask which was a rubber stopper in like teflon tape you'd get for pipes and mixed it all up until the whole thing appeared the same consistancy. I then added 80g of salt mixed with 100ml of water because I was told it would be a lot faster than the 40g cited in the video, this salt was unlabeled and it may have very well been iodized salt so I planed to do a Re-x later but I assume that this wouldn't cause my low yeild? I did not wait an hour I went and added my naptha right away and then mixed it, I think I mixed it too hard and got emulsions, so I added another 40g of salt and mixed it again, which seemed to make the emulsions clear much faster. I then did my first pull, into a jar of warmed distilled water, and used my turkey baster to sort of spray it into the water (the video I followed the same guy posted a water wash guide which I followed) once the naptha seperated from the water, I tranfered it to another jar, did the same thing again, and then added it straight to my pyrex dish. I then did this again, added more naptha (60ml) mixed it back up, waited for it to sperate, pulled it out, did the same water wash, and put it in the dish. Before the third pull I put the whole flask in a pan of hot water for about 15min, and then repeated the same process, added naptha, mixed it, waited for it to seperate and then put it in the water wash and then into the pyrex. I wrapped the pyrex in saran wrap and put it in a trashbag and then put it in my freezer which at the time was about -14c, I then left it for about 22 hours and pulled it out, poured all the naptha into a jar and kept it, waited an hour with it in the sun, upside down. Once it looked dry, I scraped it and weighed it and it was like 25mg total for my first pull. I was very dissapointed but had some ideas why it was so low so I just did another extraction, I assumed that not waiting an hour after adding the salt for it to react may have been part of it but now it had been almost a full 24 hours since I did that, and also I knew to do a warm water bath in between each pull, as well as mixing up the naptha into the soup like 3, 4 times instead of just 1. I re did the whole process but did a warm water bath for around 15mins and then mixed it up and waited for it to seperate about 3-4 times each, 4 times total each with less naptha this time, more like 40ml this was using the same naptha I did the first time. I also realized my freezer was not set low enough and switched it to -22c before my second pull. Since then I have done the same process again twice, for 4 total extractions and each time I have gotten less and less, for the 3rd I got basically nothing and now for the 4th its currently in the freezer.
Hopefully this is all understandable, I feel as if I've done everything exactly right, there were some minor issues but nothing to cause this level of low yield. I plan to try to ph strip test my soup as well as check the temp of the freezer with a thermometer to rule out those as potential issues even though the freezer should be fine, and I added 50g of lye which should have been more than enough to balance the ph. Anyway if you have any idea what I did wrong please let me know, I can explain anything you want in more detail. thank you very much.
