How do you Craft Gas w/ chemist bench?

[Clerify]

Looked up the wiki, told to use the chemist bench with Green Gems and Congealed Gas Ball to make 5 stacks of Gas. (Can't find any section to start crafting). The chemistry bench is on and have power.

What am I doing wrong here?

You need to have learned how to make Gas Collectors.
