Yes, Two of the most important things of Enameling an artist needs to learn is:

1-Understand your available fluxes.

2-Test all your enamels.

I was young once, ha and still am at heart, and remember how anxious I was to make something beautiful. I also did not want to take the time to really understand what enamels were. So instead I jumped in and made plenty of messes.

There was only one book I could find and no classes or instructors in my area.

But today there are many books and many classes. Do yourself a favor and cut many years off you bad side of the journey. Study first.
