Immediately I apologize for the “machine” translation from Google. The essence of the problem is that before version 6.09.17 you could just melt the cinnabar in a crucible, pour it into a bathing pot and then fill the bottle with mercury. In the list of changes, nothing is said about the abstraction of this function. How now to make a thermometer? There remains the option of a centrifuge, and hope that you can remove the mercury with a crane.
Take Glass Bottle, rightclick the Crucible that has enough Quicksilver to fill said Glass Bottle. You need to carefully melt 2 or 3 Cinnabar for one Bottle, one of the two was it.
And the Guide here explains it, at the very bottom of the Page.
That is, I did wrong from the start … Oh, thanks
