In 2015, I started saggar firing, and after extensive research, I stuck with what worked and stopped experimenting. But there's still a lot to discover, so it's time to pick it up again.
I've made a few jars that I'll use to explore new things, or at least things I've never done before.
This could be anything: a different type or color of clay, a different color of terra sigillata, or different oxides or combustibles.
It won't be a systematic study, but rather adding or changing something to see what happens.
You can see the results here.
Nr 01*
Clay and color: fine grog, white, withterra sigillata.
Test: use of a soda solution.
Method: Soda dissolved in water. Soak the rope in the solution.
Other pieces of rope with cobalt, manganese and iron.
Resul: nice red in one place.
End result





Nr 02*
Clay and color: fine grog, white, withterra sigillata.
Test: using rope as resist
Method: rope with knots around the piece
Then coconut fiber with cobalt and iron.
Result: In most places there is still colour, but in some places there color is lighter.
End result
