SIAK manufactures two types of glass decals - Ceramic and Organic.
Ceramic glass decals typically require firing temperatures that fall within the range of 1020°F to 1450°F (550°C to 790°C), but the optimal temperature depends on the specific type of decal and glass being used. A much lower temperature of around 1020°F to 1250°F (550°C to 675°C) is sometimes used, which allows the design to adhere to the glass surface without altering its form. Higher temperatures, closer to 1450°F (790°C), may be required for certain applications, particularly when fusing glass layers.
Occasionally referred to as cold decals, organic decals are baked to the surface at just 150 - 180 degrees celsius. This relatively low temperature gives energy saving benefits to the end user.
Glass ceramic decals, while versatile and vibrant, do have certain color limitations due to the materials and firing processes involved. The range of colors that can be achieved is often restricted by the pigments and oxides that are stable at high temperatures.
Organic decals, on the other hand do not have such restrictions. Vivid colours including bright pinks and even fluorescent pigments can be attained.
