Hi Birgit -
Traditionally terra sig is a low-fire surface. Many people are going for
maximum shine, and that is only possible at very low fire temperatures. Th=
e
shine diminishes above about cone 08. But terra sigs can be used at much
higher temperatures if you do not care about the shine. If you read my
extensive article about terra sig at

I am firing to 03, but a handout I have has recipes for cone 6 Goldart
base and also Newman and Apache Red Clay.

Because the bond is clay to clay, like attaching a handle, it is
recommended to apply at leather or bone dry and not on bisque. And
don't apply thickly.

Yes it is a low fired surface.
I published a short illustrated article a few years ago on the general
basics.
