I am after a black paint that will fire at 730 / 740 C to a gloss. Does the glassine pen fire to a glossy black? Do I need to fire at a particular temperature to get a glossy black? Many thanks
Screenline Black Enamel has a firing range from 660 - 804 which would suit you better for lower firings: https://warm-glass.co.uk/screenline-premixed-black-enamel-p-6731.html
The hotter you fire the enamels and glassline the glossier they are. (804 is the maximum)
