High-Fired Enamel Decals
Enamel decals are designed to be fired at high temperatures, typically around 600 degrees Celsius. This process fuses the decal permanently to the surface of the glass, creating a finish that is both durable and long-lasting. The high firing temperature ensures that the design becomes an integral part of the glass, offering exceptional mechanical durability.
Low-Temperature Decals
Low-temperature decals, on the other hand, are baked at much lower temperatures, around 150 degrees Celsius. While they do not achieve the same level of mechanical durability as high-fired enamel decals, they still offer excellent durability. These decals adhere to G1 testing criteria, which ensures a reliable level of performance for many practical applications. They provide a cost-effective and efficient solution for adding designs to glass without the need for high-temperature kilns. Decals have excellent lightfastness and resistance to fading.

Organic decals are an exceptional choice for decorating drinkware such as wine glasses, champagne flutes, and beer glasses. Their versatility makes them ideal for adhering to the complex curves and unique shapes of stemware. The decals are highly detailed and vibrant colours can be achieved. The organic pigments used in these decals produce rich, striking hues that elevate the aesthetic appeal of any glassware.
Unlike traditional firing methods, organic decals are baked, which helps maintain the delicate shapes of stemware. This ensures that the original form of the glass is preserved while still achieving a durable and high-quality finish. The use of a hydrous primer in the decorating water provides a good level of dishwasher resistance. This means that the decorated drinkware is not only visually stunning but also functional for everyday use, with designs that stand up to regular washing without fading or peeling.

Engineered to achieve G1 levels of scratch and chemical resistance, ensuring that branding remains pristine despite handling, humidity, or exposure to cosmetic formulas. The flexibility of a decal system offers effects like gold and silver hotfoils, photographic CMYK images, and faux-etch effects all contained in one easily applied piece. Low-temperature curing means extra vivid colours and the ability to apply on a range of substrates including coated glass.
This versatility is why some of the world’s best-known cosmetic brands turn to decals for projects that challenge the limits of automated decoration, ensuring their packaging stands apart with 360-degree coverage, intricate metallic effects, and high-definition imagery.

Glass decals play a crucial role in scientific glassware, offering both functional and aesthetic benefits. These decals are often used to label and mark laboratory equipment, such as beakers, flasks, and test tubes, with essential information like measurement scales, safety warnings, or chemical resistance indicators. The durability of glass decals ensures that the markings remain intact even under harsh conditions, including exposure to high temperatures, chemicals, and repeated sterilisation processes.
Additionally, the precision and clarity of these decals enhance the usability of scientific glassware, allowing researchers to conduct experiments with greater accuracy and efficiency. Beyond functionality, custom decals can also be used to brand laboratory equipment, fostering a professional and cohesive appearance in research facilities.

Glass Decals for Safety Marking - Glass decals are an essential solution for marking double glazing panes with safety information. These decals are designed to provide clear, durable, and permanent markings that comply with safety regulations. The decals are applied to the glass and then fired at high temperatures during the manufacturing process. This firing process fuses the decal into the surface of the glass, ensuring it becomes a permanent part of the pane. This durability makes them resistant to wear, weather, and cleaning, ensuring the safety information remains visible and intact for the lifetime of the glass.
Decals in Architectural Glass - In architectural glass, decals serve both functional and aesthetic purposes. They can be used to add intricate designs, branding, or decorative patterns to large glass installations, such as facades, partitions, or balustrades. These decals allow architects and designers to achieve a customized look while maintaining the structural integrity of the glass. Additionally, they can incorporate functional elements like privacy screening, UV protection, or wayfinding information. Fired at high temperatures, these decals become a permanent feature of the glass, ensuring longevity and resistance to environmental factors, making them ideal for both interior and exterior applications.
