How do you use the tortoise shell mortar?

[emitfudd]

I'm surprised by the lack of information online. 9/10 things I google have no results. I have crafted the tortoise shell mortar. It went into my inventory instead of being able to place it somewhere. I tried dropping it but all I can do is pick it back up. I don't see that it unlocked any new blueprints. What do I do with it?

You just need it to be able to make certain recipes from the chemistry bench.
Kinda like you need an axe in your inventory to build certain thing, it's the same for the shell mortar.
