Fundamental Underglazes were the first product line produced by Mayco in 1954 and are still a staple for many ceramic artists. Mayco Fundamentals® Underglazes are very versatile – use for full coverage or in design, apply to clay or bisque – with a wide firing range from cone 06 to cone 10. Fundamentals® Underglazes are just as suitable for the student making their first pinch pot as for the clay artist creating works for a gallery.
