We will be CLOSED on Saturday March 29th due to the NCECA conference

Mayco Fundamentals® Underglazes

Mayco’s Fundamentals® were developed by our ceramic engineer, manufactured under stringent QC standards, and tested by our staff artists for color consistency, usability, and performance on various clay bodies and firing temperatures.

Underglazes were the first product line Mayco produced in 1954 and continues to be a staple for many ceramic artists. Mayco Fundamentals® Underglazes are highly versatile – use for complete coverage or in design, apply to clay or bisque – with a broad firing range of cone 06 to cone 10. Fundamentals® Underglazes serve equally well for the student making their first pinch pot and the clay artist creating works for a gallery.
