so I just did my first extraction... few questions/comments :
Some teks call for 1g of lye per 15 of water.. I used 2l of water, which would mean 133gs of lye. When 100gs were in, ph was already over 14... When I added the powdered mimosa, it immediately turned black, which means ph was for sure high enough.. So how comes these teks out there call for so much lye? Dont their waters get high ph before that, like mine (maybe me using distilled water made a difference)? isnt all that lye unnecessary, because all that matters is ph over 13?
part of my naphta I evaporated, part I freeze precipitated, to see the difference. In the freeze precip, some nice looking white crystals formed in the side of the glass.. I took it out of the freezer, quickly poured out the naphta and put the container to evaporate. On the sides, as I said, the white crystals were nice. On the bottom, though, it stayed transparent/oily. I left it to dry for a whole day and it didnt change, the white ones were easy to remove, and stayed dry small crystal formation. When I scraped the bottom, it was some yellow oily substance which I later put together on the side of a plate to evaporate some more. It formed some medium quality yellow bit oily crystal. Is there a reason why on the bottom its different than on the sides? Am I doing something wrong?
as for the evaporation, some crystally formations appeared spread over the baking pan.. It was a pain in the ass to scratch from all that surface area though.. What is the best technique/tool for doing that? I was using a scalpel, but the ´head´ was too small I think, so it didnt scratch much at once.. Also in the evap dish, there was a part of oily yellow residue that after couple of days still was there, didnt evaporate. Is there anything wrong? Should I heat up some naphta, throw it there and suck up the naphta into a container to the freezer? but how can I know amount of naphta, since all recrystalization teks talk about amount of naphta per g of dmt, but I have no idea how much there would be there in that oily part?
