Initial testing "in panem" somewhat inconclusive due to lack of structural support in lightly-toasted substrate. Construction of a measurement jig is underway

Initial tests with a 10mm wire of approximately 2.5mm diameter (flattened to 3.3mm after several minutes on the test bench) Vegemite shows a low initial resistance of <20kΩ, rising to and leveling off at about 108kΩ ±5kΩ after some minutes of continuous measurement

A novel behavior has been observed, possibly due to charge carrier ion species electromigration through the wire substrate: After about 30 seconds off of the ohmmeter circuit, resistance drops down to <50kΩ, and begins to rise once again, soon reaching steady-state performance!

Despite the shortcomings of this testing methodology, I proceeded as best as I could with a similar Marmite wire. Unfortunately Marmite's thinner consistency made it more difficult to lay down a consistent trace. Initial resistance was ~25kΩ, rising to approximately 250kΩ.

Gravitational forces led to substantial creepage of the Marmite wire media, despite an ambient temp of ~13C More accurate tests could be done by diluting a fixed amount of each media in DI water solutions and performing inert-electrode triangular waveform conductivity testing

so we find that.. Vegemite: * holds a wire-like form better * settles at ~11kΩ/mm Marmite: * doesn't hold wirelike shape well * settles at ~25kΩ/mm Both: * start at ~2.5kΩ/mm * exhibit rising resistive behavior under DC loading * are delicious ... meanwhile, i'm still hungry

Your last point undermines the validity of all the data you've collected.

prematurely eating the experiment is frowned upon by the standards of scientific rigor
