Howdy everyone. Today I have a couple points made out of my homemade stone called princeton peanutbutter.
Princeton peanut butter was originally an ashflow-cherty-tuff which in essence is basically a pyroclastic flow composed mainly of fine ash particles. The flow, I believe (due to partial grading on the top of the deposit), had a river flowing over it before it was lithified. The bed of ash and plant debris was berried for only a short period of time, with very little heat and pressure, before it was brought back to the surface (perhaps due to isostatic rebound from the receding ice ages.)
The composition of the ash-flow must have been rich in silica and other clay minerals because when I put it in my pottery kiln up to cone 3 the stone vitrifies and changes colour.
It’s my own little homemade stone, I love working it and it makes some of the most interesting points.
This is the first point that i made out of the superheated stone. I made it the same day after the piece came out of the kiln.
Here’s a whole bunch of paleoplanet threads if you’re interested in reading more on the subject. Please excuse the bad grammar in these paleoplanet threads. haha
