Susan,

    If the problem does not clear up, it could be the Thompson's
    unleaded enamels themselves. The high firing temperature of 1600 may
    be the solution, as these enamels "mature" at high temperatures. As a
    beginner I used them in cloisonn=E9 on silver, and the results were
    similar to what you've been experiencing. 1450 as the "right"
    temperature for firing is the standard, so I did not try the higher
    temperatures until much later, as no one suggested it to me. The
    Japanese enamels are much more user friendly, formulated to almost
    uniformly mature and clear around 1450. When I teach they are the
    enamels I recommend for beginners.
