In regards to your new enamel pens, your site says to fire them at 14 to 1500 degrees, but for how long? I would love to try these, but need more information.
The multipens have been fired successfully on the bisque components without a hold time. Results vary from kiln to kiln and the results you are looking for could vary from design to design. Here is a firing schedule to test:
Firing at a lower temperature, 1,350 - 1,400 degrees Fahrenheit the enamels may retain dimension. At the higher temperature, 1,500 - 1,550 degrees Fahrenheit the enamels tend to yield a smoother surface with a nice glossy look.
