Powder Line Medium (PLM) is the generic name for a material
that compares with the commercial product "Liquid Stringer".
This recipe shows how to make your own PLM for a fraction of
the price of the commercial version.
HOW TO USE:
Mix the PLM with glass powder in a squeeze bottle. Squeeze to apply onto sheet glass.
Exact ratios of powder to PLM will vary due to the inconsistent nature of CMC, the variety of powder particle sizes and more. More powder and/or PLM can always be added to adjust viscosity.
When firing the glass consider adding a 30 minute hold at 900°F to allow the CMC to burn completely before the glass softens significantly.
