Getting the sagger smoke better now. I was getting either no smoke in the crackle or to black. Seems better now. Have worked out that by opening the sagger when still very hot i can alter the effect by re oxidizing or adding more saw dust to the bottom of the sagger.
One of my latest pots. After smoking in a sagger to 600 deg c. I got the crackle effect to stand out a bit more. Had to open the sagger to re-oxidize a bit as it was to dark. Re-oxidized at 400 deg c.
Today i applied terra sigillata to a batch of my latest shapes. I have been working to get the perfect finish
on the terra after the raku fire. This is the terra that will crack for me in the raku .
I have been trying for a long time now to get a crackle on my terra sigillata pots. I seem to have found the right method now so all i have to work on now is the smoke reaction that i am still getting on the side of the pot as i just want it in the cracks.I will change my method of terra. application next time.
Here is a comparison of the piece before and after the smoke fire. Terra sigillata raw and sig that has sintered out.
. A slab built box. Here i first put a copper carb. wash ( in the deeper parts of the surface ) and terra sigillata on before bisc. After bisc. i put on a low fire red glaze that i wiped off just so that the terra gets some color and i get a hint of red to give the pot some life. The lower part has a darker terra on and just before glaze bake i sprayed a solution of iron chromate and a frited iron on to the work to get fine spotting on the surface and to accentuate the base line and handles.
Having had to change my modus operandi due to my shoulder prosthesis giving out on me i am spending some time on final decoration and slab building as turning is just out of the question at the moment. Have time now to put some tutorials together too, will post them on completion.
These pots came out a bisc bake that was done for me. ( Thanks Veronique ). They have been colored with different Terra sigillata mixes and will now be put away for raku and saggar smoking in the summer time. Some will get a inside glaze first.
