Ironstone (PC-36) is a warm, natural-looking glaze that shifts between deep brown and soft rust depending on application. In thin coats it reveals earthy, iron-rich tones, while thicker areas deepen into a rich semi-gloss brown with subtle variation. On textured work, it breaks lighter across ridges, highlighting carved lines and wheel-thrown details. A versatile mid-fire glaze that brings an organic, timeless look to both functional pottery and decorative forms.
