Dawn, no you're not doing anything wrong, but you have to figure out what works best for you in your circumstances. If your clay matures at ^6 it will not leave much porosity to suck in water from your glaze and allows the glaze to grab onto your pot. For that reason you want to bisque fire at a low enough temperature to allow your glaze to work the best. The best thing you can do is call the clay maker and ask them what the best bisque temp for your clay and the accompanying glaze would be.
You can raw glaze. That means that you can skip the bisque process, but fire the glaze firing as if it is a bisque firing. ( slowly raising the temp.) This is however a process that require some special attention and I would recommend that if you would want to do that, find someone that is doing a workshop about raw glazing so that you can see what the glaze should look like before you fire it. etc. I am not an expert on raw glazing.
Enjoy your potting journey!
