Intercalated graphite carries a resting voltage without giving a charge.

Next question:


Is the ground wire a true earth ground?
Or tied to your house ground which then goes to earth?
On the house ground you can get a signal from each appliance
on the line with all the tv channels and the telluric


Not the current the device is using, that all goes back to the line
But a mirrored feedback of much lower intensity will appear to ground.
By turning on/off stuff in your house you can isolate individual spikes
The house currents don't normally spike like that. They hang out near
the 0 line as "fuzz". Cable signals can be the largest of those because
of so many underground lines pushing a lot of power from the tv station.
But if you wanted to isolate your house (and any airborne signals )
you can run a piece of coax straight to a rod in the earth and make an
independent ground for the experiment.


Then you will only have the feedback signals from the earth.


I'm wondering if the (avg) particle size is acting like a receiver to certain
of those spikes, amplifying them somehow?
You should run many tests and collect a lot of comparable data.
Maybe multiple identical cells side by side
narrow down what changes cause what effects etc.


Wishing I had a kiln right now.....
Highest I can go is about 700F....
You're pushing 1300 degrees!!


Fire pits don't work cause you can't really control the temp
so I can only sit back and observe atm

I have a cheap POS meter and thought maybe I was getting false readings also. I borrowed a Simpson 260 from the port captain so I could do a comparison , and these are some measurements I took. I'll have to investigate further with graphite once I get home. I have several new materials on order and I'm chomping at the bit to get started. In a couple weeks maybe I'll have something worthwhile to report.

Smoky , do all DMM have that issue or is it just the cheaper grades.

[sm0ky2]

More expensive ones have better circuits so the problem may be
less of a hassle. Some even have a button that "zero's" it out.
But yes, in short, the method of measuring voltage with a DMM
can put a charge on the circuit unintentionally.
Sometimes they will charge a capacitor while you're trying to measure it.


Yours looks pretty accurate looking at your log.
0.1v is about as accurate as you can expect a DMM to be.

Thanks Smoky, I'll put my own ground in. Been meaning to do it for a while for these sorts of tests. The Kiln is my wifes that she uses for silversmithing. Robert Murray Smith read and others papers recommend this method. I think simpler identical cells and comparison is a good idea. I'll get back to you I started this thread at overunityresearch.
