The conductivity of molten lithium carbonate has been determined for vast range of temperatures (Ref.1). The abstract of which states that: The present communication reports the results of an investigation of the properties of surface tension, density, and electrical conductance for molten $\ce{Li2CO3}$, $\ce{Na2CO3}$, and $\ce{K2CO3}$ and some mixtures ...

I understand why a HS text might call it "electrolytic" , but in the real world it is called "cathodic protection" or CP. That is what to look for on the net. It is a multibillion dollar industry. Essentially all pipelines ( oil, gas, products, water , etc.) use it . A large majority off offshore steel structures ( oil platforms, ships, etc) use it. And ...

Just remember two major rules in electrolytic electrochemistry: If you fix voltage, current cannot be controlled. This is called constant potential electrolysis If you fix the current, voltage cannot be controlled. This is called constant current electrolysis Now your electrolysis cell has resistance: (i) It will depend on electrolytes (ii) Surface area ...

Because the burr ( grinding head ) is steel and maybe the bowl it fits into , why not leave the shaft as bare steel ? As long as the beans are dry there will be very little corrosion; maybe wipe the shaft with a paper towel once a week to prevent any coffee powder from building up on it. And you could wipe a little vegetable oil on the shaft occasionally.
