About

Professional Precision Tip: The elastic 0.08–0.25mm flexible tip is designed for professional artists. It responds to pressure for graceful line variation—ideal for detailed sketching, outlining, and calligraphy on pottery bisque.
Artistic Control for Adults: This underglaze pen transitions seamlessly from hairline details to fuller strokes. It is a specialized tool for experienced potters to create intricate designs that match hand movements.
High-Temp Kiln Firing Required: Not a painted-on craft toy. This glaze must be fired in a professional kiln at Cone 5–6 (≥2167–2232°F) to become permanent. Requires strict temperature control to ensure the glaze sets correctly.
Studio-Grade Quality: Shake, press, and glide. Designed for pottery studios and workshops, this pen offers smooth delivery without clogging, suitable for complex ceramic projects.
Versatile Ceramic Application: From tiles to tableware, these professional underglaze pens are formulated for use on porous bisque. Provides a food-safe finish only after being coated with clear glaze and fired at high temperatures.
