I don't recall where I read the article. Likely PMI.
You can place the piece in a paper bag along with the combustibles and
colorants. Then cover the bag with a thick slip. Kind of like paper mache.
Let dry, fire the bag and piece. When cool, break open the clay cocoon and
you have saggared.
I have not tried it. Sounds like a reasonable approach.
