Argh! I know I ask a lot of questions, but I've tried to figure this out by myself for nearly a week now before giving up. I have no idea how to make flasks or alchemical jars, and I have never seen oil nuts or tunnel tube. None of these exist in the stocks menu, either, and the wiki doesn't give information on these particular things. Sure, I can make jars, but not -alchemical- jars. I can make vials, but not flasks (which are required to build the alchemy laboratory). I've searched all possible build options many times, but there don't appear to be any oil press or jarmakers workshop. The only thing I can press into oil is rock nuts, but considering the wiki information I assume that's a different kind of oil.
Probably going to start a new game, too many newbie mistakes made and, more importantly, NO resources to make any sort of metal bars on this embarkment site. My poor dwarves in leather armor were getting owned by invaders with WAY better equipment. I had hoped for alchemy to save me, there was cobaltite and rock crystal there, but alas I couldn't figure alchemy out.
This is way more fun than vanilla was, however... and I'm not getting owned quite as hard, so far. No invaders with flying and underwater mounts yet.
