How many diamonds is the first extra slot of the smelter? And how much is it for other machines? Also can someone confirm that smelters only have one slot at first? I seem to remember it was different from other machines.

I have three slots unlocked in my smelter and the next one costs 12. Same thing for the pasta kitchen but the next one costs 9. So either the pasta kitchen had one slot originally and the second one cost 3, or it had two slots and the third one cost 6. I think it's the latter but I'm not sure.
