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.

Fundamentals® Underglazes are AP Certified Non-Toxic and dinnerware safe when clear glaze or another glaze that creates a sealed and chemically durable finish is applied.

Fundamentals® Underglazes will fire matte without addition of a clear glaze. To intensify color or for use on dinnerware, apply clear or matte clear glaze. To create depth and contrast, combine the matte finish of Fundamentals® with a glossy glaze such as Stroke & Coat®.

Mix colors to create something new; use brushstrokes to blend colors and create shading; layer them without concern of intermixing – great for Majolica – add thin lines and details with confidence as Fundamentals® will NOT move.

For a more traditional and painterly approach, dilute underglazes with water to create a thinned watercolor-like glaze. Use these tints to layer for seamless blending.

Much like using oil or watercolor, Fundamentals® Underglazes can be used to create a life-like portrait or landscape,. Use rendering, shading, blending and other painting techniques to add dimension and a sense of realism to your work.

Fundamentals® can be used for delicate designs or all over coverage. Create variation by leaving some areas matte and others glossy with clear glaze.

Fundamentals® can be co-fired with clear glaze in a single firing. This time-saver can be valuable for those in a classroom setting. Out-gassing can trap bubbles or create craters – adding a 15 minute hold will fix most surface issues.
