I have done one extraction so far with q21q21's d-limonene tek for jimjam. I am interested in crystals however, and have no way of getting clean naptha. I will be following q21q21's tek all the way up to doing the pulls with the limonene, and then will be switching over to BLAB's tek and combining the limonene with a saturated fumaric acid solution. Then I will be mixing this solution with a saturated sodium carbonate solution and precipating the crystals in the fridge for the following 5 days. If anybody is aware of any possible problems with combining these two teks, or has input or better ways of doing it please let me know. Is this a common method to use (combining q21q21 and BLAB teks)? Otherwise I will be posting pictures with a full report on the extraction in this thread when it's finished. Thanks
