Here's a 2 foot high, 3 sided pyramid I made to sit out in our garden. It has three glazes layered on, painted from the top down to be thicker at the top so the glaze would flow downward. The glazes are variations of rutile blue. I painted an iron oxide wash at the top to bring out more blue and to provide variation with the brown the oxide is particularly thick.
The last pic shows a closeup of the glaze detail. Click on the pictures to see bigger versions.
