Using the bone ash to add to composite

23 Feb: The bone ash needs to be finer as its still possible to see the smaller pieces when mixed with the cornish stone and china clay and made into a slip.

Calcified bones

19 Feb: Collected the bones from Nick, they had been fired at 1000 degrees - Sounds like glass when knocked against each other - There is a red colouring inside some of the bones that have split (which i am assuming is cartilage) - The bones feel solid*, dont crumble at touch, but lets see what happens when they are used in the grinder

*solid in a way i dont recall them being the previous time i fired the bones, maybe they need to be fired at a higher/lower temp?
