saggar in foil - an alternative

Another alternative:
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.

the help. <
