Not quite - we're not bringing SG-101 back BUT we have a glaze mixture solution that will create a fantastic chalkboard surface!
The two products you'll need are Mayco Underglazes and Foundations Matte glazes. The ratio for the mixture is 3 parts Foundations to 1 part Underglaze.
For black chalkboard: mix 3 parts FN-304 Black Velvet with 1 part UG-50 Jet Black.
Note: the two-to-one ratio may also work; we've tested both - 3-to-one seems to be less porous and chalk marks wash away with a damp sponge more easily at the 3-to-1 ratio.
