Do you think it's more the material or the sacred geometrical shape of the pyramid that causes the effect on your water?

Bit of both really but mostly i would say it is the mix of iron powder with resin which produces the strong reaction. Iron is expensive and heavy so it is generally avoided in the orgonite industry. Replaced by aluminium which, understanding more now, i will never use again in orgonite.

Try out the shungite on the reverse osmosis system and see how it goes. Though if i had a shungite pyramid i would probably put it on the wifi box.
