SP 1220 Lobelia - Artistic Crystalline High-Fire Glaze

SP 1220 Lobelia is a glossy, reactive crystalline high-fire glaze that produces transitions in deep cobalt blue, navy, turquoise, and green tones. Depending on application thickness, dark navy may pool in recessed areas, while turquoise and ice-blue breaks may develop over edges and raised details. It creates deep, dynamic surfaces on tableware, decorative forms, and eye-catching designs.

Application and Lobelia Effect Notes

• Reactive character: The distribution of cobalt blue, navy, turquoise, and green tones may vary depending on application thickness, form, and firing conditions.
• Brush application: Applying 3 coats is recommended for a rich, layered surface. Allow the surface to dry completely between coats and apply each coat in a different direction.
• Breaking effect: The glaze may concentrate into dark navy tones in recessed areas. Over edges, raised details, and elevated areas, it may become thinner and create turquoise and ice-blue transitions.
• Crystalline appearance: The intensity of crystal-like formations may vary depending on the firing schedule, peak temperature, and cooling rate.
• Clay body selection: Navy and turquoise transitions appear brighter on white high-fire clay bodies. Speckled, grogged, or dark clay bodies may produce more rustic surfaces.
• Application thickness: Dark pooling and crystalline effects may intensify in thicker applications. Light turquoise tones may become more pronounced over thinly glazed edges and raised details.
• Mixing: Mix the product thoroughly before application to distribute the color- and effect-forming components evenly across the surface. Stir again at regular intervals during application.
• Dipping and pouring: Depending on the required application consistency, 5-10% water may be added. Add water gradually and in a controlled manner.
