tldr at the end; I am pre-blue science slowly working on mining out the required materials for blue science, among those is glass, which [skipping the chain] -> needs brine, which I have recipies for. Brine in pre-blue science state needs either rock salt or epoxy resin loop which itself requires having some brine in the first place. So I need rock salt, which I found two patches of, both waterbearing which would produce brine if I could dewater them, a process locked behind blue science, which I need rock salt for to make.
question of intent: Are there rock salt patches that are not waterbearing and I'm just unlucky, or am I stuck?
tldr: blue science and dewatering requires rock salt, currently stuck with 2 patches of rock salt that are waterbearing
