What really is Barnard Slip?

Monday 12th May 2014

These are fired bars of Barnard Slip going from insight-live.com/glossary/119">cone 04 (bottom) to cone 6 (top). It is melting at cone 6. Porosity is under 3% and the fired shrinkage above 15% from cone 1 upward. Drying shrinkage is 4% at 25% water (it is very non-plastic). The darkness of the fired color suggests higher MnO than our published chemistry shows.
