I was really interested in the multipen product when you said it could be used on glass as well as the bisque. But when it said it was to be fired in a kiln (which I have for ceramics) I was confused because you wouldn't fire glass in that kiln. How do you use it on glass or metal? Can it be used on glazed ceramic pieces without being re-fired? The short description didn't explain any of that.
The enamel pens have been used successfully on glass in an electric kiln with a controller or cone system. To have a successful fuse between the enamel and glass, you need to allow the enamels to dry thoroughly then fire the kiln for a full fuse. Suggested firing temperature range is 1,450 - 1,550 degrees Fahrenheit/Cone 014. It is recommended to fire any glass product, including the enamel pens on a kiln shelf, as well as to either place a piece of kiln paper on the shelf or treat the shelf with kiln wash before firing to prevent fusing the glass to the walls of your kiln.
Here is a firing schedule for you to test:
Ramp 1 - 300 degrees Fahrenheit Fire to - 1,000 degrees Fahrenheit Hold 20 minutes
Ramp 2 - 300 degrees Fahrenheit Fire to - 1,150 degrees Fahrenheit Hold 15 minutes
Ramp 3 - 600 degrees Fahrenheit Fire to - 1,250 degrees Fahrenheit Hold 30 minutes
Ramp 4 - 600 degrees Fahrenheit Fire to - 1,480 degrees Fahrenheit Hold 20 minutes
Ramp 5 - full speed Fire to - 1,000 degrees Fahrenheit Hold 1 hour
Ramp 6 - 90 degrees Fahrenheit Fire to - 960 degrees Fahrenheit Hold 1 hour
Ramp 7 - 120 degrees Fahrenheit Fire to - 750 degrees Fahrenheit Hold 10 minutes
Ramp 8 - 300 degrees Fahrenheit Fire to - 100 degrees Fahrenheit No hold time
The number following the Ramp is the temperature incremental the kiln should increase by hour.
The number following the firing temp is the maximum temperature you are ramping up to.
The hold time is the length of time the kiln should hold the temperature at before going to the next Ramp.
