So I recently had to switch to acacia confuse root bark and I tried to use my normal stb tek on it, to very little success. Only got about 2 normal dosages from stb. I am now planning to try an A/B tek on it but am a little confused. how my old stb tek worked and what I tried on acacia bark was I dumped 50ml of lye into 600ml of water and then dumped 50g of shredded bark into it. couple of good shakes and then let it sit for 6 hours with a couple of shakes in between. I then would add 50ml of naptha and stir and then suck it off and put into freezer. I don't exactly get how the A/B teks work. What can I add to my old way of doing it to make it an A/B tek? I have tried to look up every A/B tek to try and understand what acidfy to base really means and what I have to change but its a bit confusing to me. I know this is a boring and repetitive question but its killing me! I cant seem to find a right way I can pull it of. thanks
