More glazing questions...

I've read several times now about projects with glazing done on greenware. Has anyone used this process and what are the pros and cons?

I mentioned before that I have a Terra Cotta Pottery Coat glaze I like, but it's tricky to use. I was thinking if I could apply it to greenware, bisque fire, then apply the Stroke and Coat pattern on top, it might get the glossy/matte contrast effect I want. The other way I thought about was to outline my pattern, then paint the two separately after the bisque coat. I'll be applying a regular glossy glaze on the inside to make it waterproof. Does this make sense?
