Crystal Power CeLL by John Hutchison

@ Ian:

We used two different types of waxes for this.  The strongest was called "brown wax" and had ceramic powder mixed in.  You could only hold tolerances of +-.001" (on a good day) with this wax.  It was strong, but not accurate.  The second wax, which was marketed as "beeswax", was much thinner and had a lower melting point.  With experience, we could hold tolerances of +- .0003".  It was not as strong but melted much flatter.  I wish I still had my sources for these materials but I do not.  For really accurate work, we would make vacuum chucks that used vacuum to hold precision parts on the magnetic chucks of the grinders.  Using these, we could routinely hold +- .0001".

Jewelers use dop wax for both faceting and making cabs.  This is commercially available.  I hope this helps.  Let me know if you want more detailed info.

@ Bill

Thanks for the info. The wax mixed with ceramic powder is most interesting. .

If memory serves, the ceramic powder was AL2O3 at about 85% purity.  It has a slightly higher thermal expansion than 99.7%.

For q-cell construction(i don't know how to make a link)check out the thread here called "common batteries are free energy sources"It's buried in a post on the second page of the thread.I don't think all the details are there but there's a lot to work with.Also there's lots of manmade tourmaline for sale on the internet.Also the real stuff too.A lot of waxes have high dielectric values.I think that the ceramics called" the titanates" might be the way to go.Triffid

Optically clear quartz crystals have a dielectric value of about 4.2.Sand has a high percentage of broken quartz in it.So thats why I thought(guessed) sand would have a dielectric value around 4.2.
