I integrated two thrown pieces into one vase...shown below as it waited to be bisque fired.
Then dip the lower half in Raspberry (looks green but won't be when fired!)...which should form some mottled coloration, perhaps some blacks.
Then I dipped the upper half in Plum, which goes blue/green, a shiny glaze. Plum is the same base glaze as raspberry with some cobalt. And sometimes some nice drippy effects. I had waited till the first 2 glazing dips were almost dry, certainly enough to pick the vase up in those areas.
Here's the finished piece. Those drips did some pretty things!
Do not be small minded. Do not pray for gourds and pumpkins from God, when you should be asking for pure love and pure knowledge to dawn within every heart.
