At this time, the composition of Buddhist patterns can be printed on the silver plate, and after the lines are made, the concave lines of Buddhist patterns can be formed on the silver plate. In order to achieve the desired effect, it is necessary to constantly temper and knock until the effect is achieved.
Because there are 452 precious stones embedded in the Seven Treasures Ashoka Tower, some of which are special-shaped, it is necessary to dig a round nest on the silver plate according to the precious stones. Take down the silver plate, clean it, bend it, fold it, and make a frame when combining it, because putting the gold coffin and the silver coffin in the tower takes up a lot of space.
This space is made of wood "Daphne" and will remain unchanged for thousands of years. Artisans will make silverware with Buddhist patterns with silver stripes, wrap it on the frame of Daphne, fix it with rivets, and install various silverware. Finally, the finished silver Ashoka Tower will be cleaned, removed, inlaid with jewels and then gilded.
The ancient gold plating process does not change color, and it is firm. The gold is bright and shiny, and it is as luxurious as new. Bronzing is an ancient traditional process in China, which is called fire gold plating, mercury gold plating and mixed mercury method. Gold plating is a traditional metal decoration process, which has been produced since the pre-Qin period. This is a traditional practice, which is still popular among people. Popular in the Eastern Zhou Dynasty and after the Han Dynasty, it was one of the most commendable bronze surface decoration technologies at that time. It was called gilding, gilding, gilding, gilding and gilding, and it was called gilding in Song Dynasty.
The process of this technology includes four processes: killing gold, smearing gold, opening gold and calendering. First, gold is forged into gold foil, cut into pieces, heated to about 400℃, then mercury is poured in, stirred to completely dissolve gold in mercury, and then cold water is poured in to cool it, so that it becomes a silver-white paste of gold and mercury mixture. This liquid is commonly known as gold mud, and this process is commonly known as "killing gold".
Secondly, after the copper rust on the surface of copper ornaments is polished by grinding charcoal, the mixed solution of gold mud, salt and alum is evenly coated on the surface of the utensils with a "gold-coated stick", and the metal structure is compact and firmly attached to the utensils. This process is collectively referred to as "gilding".
Then bake with charcoal fire at a suitable temperature to evaporate mercury, and the gold is fixed on the bronze ware, and its color changes from white to golden. This process is collectively referred to as "opening gold". For example, in actual operation, after four times of gold plating, the thickness of gold layer can reach 36 microns.
Finally, use a brush dipped in sour plum water to brush it again, and use agate or jade to make a "pressure" along the surface of the object. Make the gold-plated layer compact and firmly combine with the casting until a shiny gold-plated layer appears on the surface. This process is collectively called "calendering". Such a beautiful gold-plated piece was born.
