Overglaze

So I'm using some glaze from Duncan Ceramics. I screwed up of course. The directions said:

1. Apply to shelf cone 04 bisque.
2. Fire to shelf cone 06.
3. Clean up with water.
4. For clear glaze application, brush-on or dip clear glaze over Concepts.
5. Stilt and fire to shelf cone 06.
6. Water clean up.

Somewhere in the course of reading stuff, I stumbled upon something about matte or flat underglazes. I made the wrong assumption that all of them are matte. So then it made sense to fire it, apply the clear glaze, then fire it again 2 cones lower.

Well, not so much.

With this system the clear glaze is supposed to go on before firing. Fortunately the underglaze is also OK to fire alone. So the bowl was not wasted.
