In Topic: Scaling Down Terra Sig

26 July 2014 - 06:50 PM

Here is a way and fast way to make #simple Terra Sigillata:

                        Fill a plastic liter bottle with 3/4 full of water. Add 100 grams of ball clay and a couple drops of Darvon 7, or Darvon 811 or sodium silicate. Add more water until the bottle is almost full. Put the top on tight and shake well. Let the mix set for an hour or so..until you see three separate areas of the mix. Clear, light and dark. If the top layer is completely clear, add more Darvon. You want some color in the top layer. Punch a hole at the bottom of the middle layer and let it squirt into a bucket.  Wait  until your piece is bone dry and apply to the piece with a soft brush. Burnish after each application. I use a soft sponge for burnishing. You can apply several coats as until it is shiny. Too much Terra sig can lead to peeling or cracking. Bisque to Cone 09 or 1670 F or 901 C

There are many books out there.

Steve Branfman's Raku; A Practical Approach 2nd Ed. or Mastering Raku

Robert Piepenberg Raku Pottery (1970)

Advanced raku Techniques by Bill Jones

Raku Art and Technique by Hal Riegger , 1970

There are many newer books out there. Also you can go to CAD and look up the subject.

I will be having a dvd coming out soon covering Raku and some other techniques.

The glazes would be completely different because they would be oxidized and not reduced. A simple description would be a copper luster would turn 

green or turquoise and the body would be white not black.


In Topic: Removing Excess Clay Before Cutting Pot Loose From Wheel.

I use the pointed end of a modeling stick for trimming the excess clay off. First along the bottom side to the bat, then lift under it along the batt surface and remove it. Then cut off with a wire tool.
