I've finally convinced my wife to let me use her kiln, that she uses for precious metal jewellery work. It has ramp up settings but I could not work them out. So I took my plant material up to 1328f over about an hour. I was hoping to ramp up over two. Then let it bake for 2 hours and cool down over 5. I soaked the material in ferric chloride so now I have a conductive ferro magnetic carbon.

Hi Jim.

That's a nice piece of kit mate!

The furnace's that I used to use were a lot more crude, Gas fired and noisey, particularly when melting castIron.

Hmmm, plant material you say. A " taboo " kind of, unmentionable plant?   ;)

Cheers Graham.

Programming the ramp up sequence does my head in. 😇

ferric who ?
Have you posted a link somewhere to the theme ....or roots/goals...of this research ?

thanks for starting the topic and sharing.

How magnetic is it Jim?
Anywhere near that of ferrite?.
If so,you have just given us a very easy way to make ferromagnetic cores of any shape and size  O0

Hey Chet.

If you quickly check the " shout box " Jim mentioned something about Robert M Smith, nailing a battery??

Ferric Chloride is a very well known chemical amongst the DIY circuit board makers of the earlier period. We used it to etch away the unmasked Copper from the Paxolin backing to make PCB's.

Being a very naughty daddy, I had left a cupful of the solution on the kitchen window sill whereupon my middle daughter espied the tasty beverage. She went to great lengths to taste this " new " drink that her dear father had left out for her. Stacking a couple of kitchen chairs she managed to reach what I thought was the " unreachable " and got a nasty shock! Thank goodness for the gag reflex, and Bicarbonate of soda. Father and daughter both learned an important lesson.... Now part of family history.

Cheers Graham.

Bloody hell Grum !
Chet like many been following RMS for a while but him driving a nail through his battery finally got me off my arse. https://www.youtube.com/watch?v=RJDaNgjrVWA Ferric chloride is also used in acid etching concrete.

Brad it's very light material and behaves a lot like iron filings when powdered. Not sure how I measure much else with but I'm guessing the longer you soak it the more Fe content you will have.

 Used half a cup of water in a blender with about a gram of carbon and some paper towel. Strained over a stocking on 100mm pipe. Drained pressed now drying. Baking some more carbon with slower ramp up and a week of soaking in ferric chloride

It's turtles all the way down
For those interested in batteries, this video is a nice explanation of the liquid metal battery.

For educational purposes only, I'm not recommending you try to build one, but there is much to learn in this video.

Jim, if off topic just delete it.

JimBoot,

Could you give us an overview of which type of FWG battery you're
working on and what it entails?  Robert Murray-Smith's channel has
a plethora of really interesting video projects.

Yep I'm starting here https://www.youtube.com/watch?v=dFrpoRzdINA I'm not using Graphene. For conductivity I've soaked my plant material in ferric chloride.
Then I'll be moving onto the separator creation. https://www.youtube.com/watch?v=-g9MQ8e93Yw
