Subject: can i make an electret from basalt (or granite) and barium titanate?

Basalt and Granite exhibit millivolt potentials, so, when melted into a lava and
cooled, where it becomes obsidian glass... if i apply a high voltage electric
field to the cooling glass (mixed with barium titanate), would the resulting
glass have a permanent electric field (Kvolts?) 

(electric rock analogue of the permanent magnet)
(((This is a Thomas Townsend Brown antigravity petroelectric inspired idea)))
