How will this glaze affect the finish and colour of my pottery?

The Sax True Flow Gloss glaze produces a high-gloss, opaque finish with saturated colour intensity—Old Navy gives a deep, navy-blue tone that remains vivid after firing. Because it’s formulated for consistent flow, it levels well on bisque ware to minimize brush marks and pinholes.

• High-gloss, glass-like surface for enhanced colour depth
• Opaque coverage to mask bisque or underglaze beneath
• Flows and levels for smooth, uniform coats
• Retains brightness through recommended firing range

What firing specifications and safety standards apply?

Fire Sax True Flow Gloss to cone 06–05 (low-fire) to achieve dinnerware-safe surfaces; follow kiln manufacturer guidelines for ramp and soak to avoid defects. The glaze is lead-free and meets ASTM D-4236 labeling standards for art materials, making it suitable for educational settings.

• Recommended firing temperature: cone 06–05 (low-fire)
• Lead-free formula suitable for food contact when fired to spec
• Complies with ASTM D-4236 for art material safety labeling
• Store tightly sealed to preserve consistency and prevent skinning

How should I apply Sax True Flow Gloss for best results?

Apply the glaze by brushing, dipping, or pouring—its true-flow formulation is forgiving and self-leveling. For even coverage, apply two thin coats, allowing each to dry before the next; avoid excessively thick layers to prevent crawling or running during firing.

• Brush on two thin, even coats for consistent opacity
• Dip for complete coverage on small to medium pieces
• Wipe foot rims before firing to prevent sticking to kiln shelves
• Stir gently to reincorporate settled pigments; do not aerate

Will the colour vary with different clay bodies or underglazes?

Yes—final colour can shift slightly depending on your clay body, slip, or underglaze choices and firing cycle. Test tiles are recommended to see how Old Navy behaves with your specific materials and kiln temperature, especially if layering over stains or textured surfaces.

• Porcelain vs. earthenware can change surface brightness
• Underglaze or stains underneath may show through slightly at thin spots
• Kiln atmosphere and firing schedule can affect sheen and hue
• Make test tiles to match colour expectations before production
