That won't work. If you simply paint the glass paste onto the outiside of bisqueware, the glass will melt off. Pate de verre requires a lot of steps, and you really should get a book on the subject, but to give you an idea, I'll detail my first small pate de verre item:
1. Used a small bisque bowl as a mold, 5 inches in diameter at the rim, about a 45 degree slope, 3 inches tall. Gave the bowl about 5 coats of glass kiln wash (Bullseye brand).
2. Mixed wallpaper paste with water until smooth (follow package directions for mixing), then mixed the wallpaper paste with medium Bullseye frit. This frit is about the size of sugar granules.
3. Used a spatula to apply the frit paste to the inside of the bowl, from the bottom up. Apply it as evenly as possible. I applied the frit to about 1/4 inch thickness, and tried to keep the rim edges as even as possible; this was challenging.
4. Allow to dry thoroughly. I let it stand for a couple of days, but probably 24 hours would have sufficed.
5. Filled the inside of the pasted glass with talc (available from pottery suppliers) to keep the glass from pooling to the bottom of the mold during firing.
6. Fired it to a typical full fuse fire, but soaked it for 1 hour.
This gave me a nicely formed, simple bowl with a pretty sugary surface. But to do anything interesting you need to learn to make molds out of materials other than bisqueware, as well as using different sizes of frits, how to colour them yourself and the list goes on. Here's an online source with good intro information:

I also recommend "Pate de Verre and the Kiln Casting of Glass" by Dan Fenton and Jim Kervin. Got a copy recently from Whitehouse Books on sale for $36, regular price $45.
Good luck!
