Q＆A
Liquid Gold
The gold color appears blurred.
The Liquid Gold has been over-thinned with Thinner. To allow some of the solvent to evaporate, leave the bottle open for a while.
When drawing gold lines, the Liquid Gold flowed.
When applying Liquid Gold with a brush, pooling occurred.
The Thinner is drying too quickly, or the Liquid Gold was applied too thickly. Use a fast-drying Thinner, or squeeze the brush and apply the Liquid Gold at an appropriate thickness.
The Liquid Gold feels harder than when purchased and is difficult to apply.
If the Liquid Gold is left standing for a long time or stored for an extended period, the solvent may evaporate, increasing its viscosity. Dilute with Thinner, or if lumps appear or it has become jelly-like without dissolving, it is likely deteriorated and should not be used. Please contact us, and we will measure the remaining amount and replace it if necessary.
After applying and firing the Liquid Gold, part of the surface appears bumpy.
The surface of the body was contaminated with dust, fingerprints, condensation, or other impurities before application. Please ensure the body is clean before applying the Liquid Gold.
The gold color does not develop properly.
The airflow inside the kiln is insufficient, and proper ventilation is not occurring. Increase the airflow in the kiln to improve ventilation.
The temperature rise between 200℃ and 400℃ is too fast. Reduce the heating rate.
There are too many items in the kiln, which hinders proper airflow. Reduce the number of items and fire again.
The Liquid Gold peels off or flakes after firing.
Surface contamination affects adhesion, so make sure the substrate is clean before application.
Applying too thickly makes the Liquid Gold more prone to peeling, so apply it evenly in a thin layer.
After firing, the durability of the Liquid Gold is low, and it gradually disappears.
If the firing temperature is too low, adhesion will be weak. Fire at 700℃–800℃.
If the Liquid Gold layer is too thin, durability decreases. Apply a thicker layer.
Upon close inspection, several fine pinholes (tiny holes) appear.
Pinholes may occur due to moisture on the surface of the substrate. When moving items from a cool place to a warm place, invisible condensation can form on the surface. Allow enough time for the condensation to evaporate and for the substrate to dry.
After firing, the Liquid Gold may flow, become narrow, or form tear-shaped lines.
If there are too many items in the kiln, airflow is hindered. Reduce the number of items and fire again.
If many items have decals applied, the gas amount increases, affecting the Liquid Gold. Use gas-resistant coated Liquid Gold or, until reaching 400℃, slightly open the kiln lid to vent the gas.
When washed in a dishwasher, the gold parts deteriorate quickly and the color fades.
The Liquid Gold may have been over-thinned or applied too sparingly, resulting in a thin layer. Do not over-thin, and ensure an application amount of 0.20–0.30 g/100㎡.
If a low-gold-content Liquid Gold was used, adhesion may be weak.
Use a more durable Liquid Gold suitable for dishwasher use. (We can offer suggestions upon request.)
If the firing temperature is low, adhesion of the Liquid Gold is weakened. Raise the temperature to 700℃ or higher.
Although the same amount of Liquid Gold is used as that of other companies' products, the number of plates that can be coated becomes smaller.
Since Liquid Gold dries quickly and has high viscosity, it tends to be applied thickly, so please dilute it to adjust the viscosity.
Because there is compatibility with the substrate or glaze, please contact us once.
Since our product has a light raw color, it may look like a thin coating at first glance, but in fact it may be thick, so in that case, please contact us once.
After firing, black spots may appear on the gilded area. Even if you repaint and refire, they may not disappear.
Gases such as carbon may be generated when resins or similar materials burn, causing cloudiness, black spots, or pinholes. Keep the kiln lid slightly open until the temperature reaches 400°C.
