The finishing is the last phase in the production process and is the real skin of the glass block.

Satin finishing, successfully tested in many applications within the glass industry, moderates and diffuses the passage of light with varying intensities according to the glass block characteristics (color, design, and whether the finishing is on one or both sides). The resulting effect is of refined elegance, giving the glass block a smooth and silky appearance.

With the use of special masks it is possible to design symbols, logos, and images, in negative or positive contrasts, with the satin finishing on one or two sides of the glass block. Like the glass block designed by Daniel Tai for the “Buddha Lecture Room” of the new religious library in Taichung, Taiwan, capable of softening direct sunlight while reflecting a magical myriad of small Buddhas in prayer.

Different optical effects and surprises can be achieved by simply changing the finishing on the glass block. Painted metallic edges can hide the gap between glass blocks, increasing the brilliancy and transparency of the glass block wall or structure, thanks to the mirroring effect of the paint.

Whether painting the bands or applying a finishing to the glass block, these additional processes can be completed with small investments.
