Have you measured the resistance, breakdown voltage and capacitance using castor oil and glycerin? If so, I would be interested in the results

>For a while now I have submerged capacitor arrays in dielectric media to suppress corona,. arc-over, etc. I first used castor oil (K=4.7) and that worked fine, but it's not so easy to get. I read on a list dielectric materials that glycerin has a high K (47-68!) but I was afraid that, being anhydrous, it would absorb water and lead to corrosion. I set up four 20KV caps in parallel in a bottle and filled it with off the shelf glycerin, the USP kind sold as an emollient. After more than a year there isn't a speck of corrosion on the caps or linking hardware.

Now, corn syrup ought to considerably cheaper than castor oil or glycerin. I think I'll start a new bottled array soon. I don't suppose anyone out there has tried this already?
