Gold! Gold! Gold! Gold! Gold! Bright and yellow, hard and cold Molten, graven, hammered and rolled, Heavy to get and light to hold, Hoarded, bartered, bought and sold, Stolen, borrowed, squandered, doled, Spurned by young, but hung by old To the verge of a church yard mold; Price of many a crime untold. Gold! Gold! Gold! Gold! Good or bad a thousand fold! How widely it agencies vary, To save - to ruin - to curse - to bless - As even its minted coins express : Now stamped with the image of Queen Bess, And now of a bloody Mary.Thomas Hood :Gold!
How are the flakes of gold dispersed within the liquid gold? Is the distribution of flakes even?
The liquid gold has two kinds of bright and matte. A gold and the element as other additive agents is contained in bright gold in the form where it reacted to resin (resinate). Except in special cases,it is a liquid which does not contain gold powder or the powder of frit at all (powder-free) . Therefore I can maintain a very stable dispersion state. On the other hand, with mat gold, in order to control gloss, gold powder of big specific gravity is blended so much. Therefore, it is comparatively easy to precipitate, so please, agitate well before an pplication.
What is the best way to apply it?Liquid gold can be applied by brushing, dipping, spraying, or spin coater. (We have not yet the experience、but we think that we can it even for a dispenser or ink-jet if we adjust some liquid.) Paste can be directly screen-printed to a base material. With special-use paste, pad printing is also possible. As an indirect method, printing on a paper for decal is also possible. Because of the use of resin that is combustible at a low temperature, be sure to dry lower than 150℃ and for only around 15 minutes. When the temperature gets too high, or when there is a sudden increase in temperature, cracks can appear in the film.
What is the normal thickness of liquid gold or paste gold after it has been fired.From our estimates using Nagoya University's ultra-high voltage electron microscope, liquid gold has a thickness of roughly 0.1 microns(100nm), and paste has a thickness of roughly 0.2 microns(200nm).
About environment at the time of the application of the liquid, please teach the point where you must be careful about.The film on a fired good is extremely thin, so after firing even wiping the applied area with lint or similer type of cloth can cause holes or cracks. Because of this, in order to maintain a high quality, please, apply the liquid gold in the area that is as clean as possible, with no trash or dust. Please be aware of the not only the tools being used, but also any loose hairs or stray paper that cloud be lying around.
A clean room is ideal, but in distances when that is not possible because of expenses, portioning an area of one room and wiping down the area with a damp cloth is very simple and effective. The method that we suggest the most is to apply the liquid gold on a mesh belt at the opening of the kiln, so once you have done the application, you can directly place it into the kiln. By doing this, you decrease the chance of dust getting onto the item, as well as decrease transport time and lead time, increasing both quality and efficiency, which in turn reduces cost. Because pottery is an insulated item, there will inevitably be some static electricity, especially in dry climates or in winter. To prevent too much build-up, use a humidifier or a grounding apparatus. Sometimes there is dust or make-up remnants in the base materials themselves, which can cause the liquid to burst or can cause cracks to appear after firing, so please check the cleanliness of the base materials as well.
