Glow in the Dark Pottery Glaze Aqua - Low Fire Cone 06

In this review of Penguin Pottery's Glow in the Dark Pottery Glaze in Aqua, the bottom line is simple: this product is for potters who want an easy, low-fire way to add visible luminescence to decorative pieces and seasonal projects. The reviewer found the glaze straightforward to use on greenware, bisqueware or already-fired pieces and especially valuable for Halloween, gift items, and novelty decor because it reliably stores light and glows after exposure. It is a specialty finish best applied where appearance matters rather than food safety.

Key Features

• Exclusive formula: A glow-in-the-dark ceramic glaze developed by Penguin Pottery after months of research that produces luminescence when exposed to light.
• Low-fire cone: Designed to be fired to a fast cone 06 so the glow particles remain effective and predictable.
• Versatile application: Can be brushed onto greenware, bisqueware, or even painted as a third firing on already-glazed high-fired pieces.
• Rechargeable glow: Absorbs UV or daylight and slowly releases light in dark conditions, with longer exposure yielding longer radiance.
• Finish options: The glaze has a non-glossy texture by itself but can be topped with a compatible low-fire clear glaze for a glossy finish.
• Lifetime warranty: Penguin Pottery backs the product with a lifetime warranty covering refunds or replacements if issues arise.

Who It's For

The glaze is ideal for hobby potters, craft instructors, and makers creating decorative pottery, seasonal decorations, or novelty gifts who want a simple low-fire solution to add luminescent effects. It is especially useful for projects where visibility in the dark is a selling point, such as Halloween props, nightlight-style pieces, and eye-catching ornaments.

It is not intended for functional dinnerware or food-contact surfaces since the product has not been tested for food safety; anyone seeking a food-safe, high-temperature glaze solution should look at certified food-safe glazes instead. Also, kilns must be temperature calibrated because firing hotter than cone 06 can reduce or eliminate the glow.

Pros & Cons

Pros

• Unique glow-in-the-dark effect that recharges with UV or daylight for decorative impact.
• Works on greenware, bisque, or as a specialty third firing on finished pieces for flexibility.
• Low-fire cone 06 firing keeps the process accessible to studios using low-fire kilns.
• Lifetime warranty provides confidence and support if there are problems.

Cons

• Not glossy by itself and requires a separate clear low-fire glaze for a shiny finish.
• Not tested for food safety, so it should not be used on items intended for eating or drinking.

Frequently Asked Questions

Can I fire this glaze hotter than cone 06?
Answer. No, firing hotter than a fast cone 06 can reduce or eliminate the glow, so follow the recommended temperature and confirm kiln calibration.

Will the glaze glow without UV light?
Answer. It needs exposure to daylight, UV, or other light sources to charge; after adequate exposure it will radiate in the dark.

Is this glaze food safe?
Answer. The glaze is nontoxic but has not been tested for food safety, so avoid using it on surfaces that will contact food.
