If you are dealing with power conduction, yes you will have a resistance issue.
If you have high voltages, such enviroments may be at risk for plasma discharge.
If you are looking at voltage measurement and a high impedance measuring device at a distance, the resisance will have zero effect. But you might have some unintended thermocouple voltages that would be a source of errors.
If you have a current loop instrumentation setup, again, the resistance of the conductors will have no effect.
Note that glass, when melted, and at some point before it appears to be fluid, becomes conductive. In an experiment, I saw a glass sample sort of explode in a way. The fuses in the power feed blew out. So it was a liquid phase plasma discharge for an instant? So watch for melting refractory or mineral fluxes and slag. Perhaps molten glass could be heated with RF or induction, as well as conduction.
