KINGSTAR GLASS
Blue Painted Glass | Opaque Decorative Architectural Glass from KINGSTAR BUILDING GLASS
KINGSTAR BUILDING GLASS Blue Painted Glass is a premium opaque architectural glass created by applying a durable, high-quality lacquer coating to the back surface of high-clarity float glass. The result is a glass with a vibrant, uniform, brilliant blue color that is fully opaque, offering a bold, contemporary aesthetic for interior applications. The paint is applied to the rear face of the glass, meaning the glass is viewed from the uncoated side—protecting the color application from scratches
Blue painted glass—also known as back-painted glass, lacquered glass, or opaque glass—is a decorative flat glass produced by applying a durable lacquer coating to one surface of high-quality float glass. The coating is applied using precision techniques and then oven-cured to permanently bond it to the glass surface.
Unlike body-tinted glass, where color is achieved by adding pigments throughout the glass melt, blue painted glass starts with clear or ultra-clear float glass and adds the color as a surface layer. This results in a brilliant, highly reflective, and uniformly opaque finish that cannot be achieved with tinted glass. The coating is applied to the back surface, meaning the glass is viewed from the uncoated side—protecting the paint from scratches, wear, and environmental damage.
Blue painted glass is produced using clear or ultra-clear low-iron float glass substrates, ensuring a bright blue appearance with minimal color distortion. The glass can be finished with a glossy appearance. The paint is resistant to humidity, making it ideal for use in high-moisture environments such as kitchens and bathrooms.

Q1: What is the difference between blue painted glass and blue tinted (body-tinted) float glass?
A: Blue painted glass starts with clear or ultra-clear float glass and has a durable lacquer coating applied to the back surface, creating a brilliant, opaque, and highly reflective blue finish. The color is on the surface and is viewed through the clear glass, which protects the paint from damage. Blue painted glass is 100% opaque and offers superior color brilliance and consistency. Body-tinted blue glass has color pigments mixed throughout the glass melt, resulting in a translucent rather than opaque appearance. Painted glass is the preferred choice for applications requiring full opacity and a bright, reflective blue finish.
Q2: What is the light transmittance of blue painted glass and can it be tempered?
A: Blue painted glass is 100% opaque—zero visible light passes through. No, blue painted glass cannot be tempered because the organic lacquer coating decomposes and carbonizes at the high temperatures required for tempering (approximately 600°C+). The coating would burn, discolor, bubble, and lose adhesion. For safety glass requirements, glass must be tempered BEFORE painting, or ceramic frit (screen-printed) glass must be used instead.
Q3: Can blue painted glass be laminated or used in insulating glass units?
A: Yes. Blue painted glass can be laminated with PVB or SGP interlayers and can also be used in insulating glass units (IGU), with the painted surface facing the cavity to protect the coating from damage. All cutting, drilling, and other processing must be completed before painting, as no further fabrication is possible after the coating is applied.
Back painted glass is a unique use of glass that has been growing in popularity in recent years. It is essentially exactly what it sounds like- glass that has been painted on the back side. That way, from the front side, the glass is no longer translucent, but instead a solid color.
Thickness: 3mm 4mm 5mm 6mm
size: 1830*2440, 3300*2140mm
The applications for back painted glass vary widely and it is commonly used in both residential and commercial buildings. One of the main uses of back painted glass is simply as a design element. Glass has always added a unique look in any building project which usually translates to a sleek, modern appearance. Back painted glass takes this one step further in that the cool, hard surface remains, but color is added to match any palette.
