Hi, I'd like to build a homopolar generator. Since generating magnetic fields of uniform density of any useful size is very tricky to do with off the shelf permanent magnets (I've tried!) I had the idea to use DC solenoids instead. But with a rotating helical plate in place of the cylindrical...

Could I minimize the latter danger by drying the samples prior to compression? I have an ultrasonic agitator available although the frequency range is fixed. I am thinking I can vibrate bubbles out while the mixture is still liquid, then dry the mixture solid, then cut it into discs. I am not...

Hm, that's a good point. Maybe I'll stay at room temperature & devise a piston with Bridgman seal. I'll bury it outside inside a cinder block so if it bursts it doesn't break anything important.

Hi, I'm hoping to make small batches of synthetic minerals by compressing & heating small liquid or semi-liquid samples of sodium silicate w/ variable amounts of other salts dissolved within. As I understand it, many of these will require high pressure & temperature to form. So my strategy is to...
