Thanks for coming back Again. So You are Curious about to know how they make lost wax statue? Hope you have read my privious post for making Lost wax statue Part 1 . (click if you have miss the last post) In last post they have Placing the crucibles in the bed of coke filled with metal. The entire furnace temperature goes up to about 1800 -1900 degrees. So after This It's Left Only The Empty Mold all The Wax melt in High Temperature..so here we go to see after work...
Setting up empty molds in between the refractory bricks to receive the molten metal. Handling the molds with asbestos gloves and bracing them with fragments of bricks.
Pouring the molten metal into the base of a Empty mold
The first metal image from the day's work. Examining the image for flaws
Two auras (prabhamandalas), one that cast perfectly and one (in front) that only partially filled. Opening more molds with Raw statues Researchers mark specific metal images for future identification. Cleaning the details of the image with a metal tool. Sawing off the sprues from Aura image. The sprue metal will be reused in future castings. Two auras that worked perfectly. The one on the right has been cut off of the sprues, while the one on the left still has the sprues attached.
The finisher's tools and the work in progress Finishing work on an image of the Buddha. Hammering the chest of an image that is being held against the work block A Buddha image hammered and chased to the final, detailed finish. Cleaning in a very mild acid bath. The image and prabhamandala are placed in a final acidic bath to make sure the surface is absolutely clean. Drying the image with a blow torch.
Tools and materials for fire gilding. ie: mercury, gold powder, brushes etc.. Tools for fire gilding: the blow torch, a brick, oil etc... Anthor specialist applies the mercury and gold amalgam to the surface of the copper image.
Cover the whole image with the amalgam.
Every detail must be perfectly covered.The spreading of the amalgam is a painstaking and detailed job.
The artist finishes applying the amalgam to the figural portion of the Buddha image. The lotus base is also covered with the amalgam, and the image is placed on a brick to dry prior to the heating process. A final touch-up of the amalgam coating. The image is placed in a basin of water to cool prior to the final process of blending the amalgam.
The image is placed on the brick and the final blending of the amalgam is done. The image is then rubbed with cotton to spread the amalgam evenly. When the heat from the blowtorch is applied, the mercury begins to vaporize leaving a very thin layer of gold on the surface. As the heat spreads through the copper image, the change in color happens very quickly. The aura is then heated with the blowtorch. Both the image and the aura are cooled in a bath of plain water. The image has a mat appearance and looks as if it had been spray painted, rather than gilded. Note that several areas on the base did not have sufficient gold to turn color. These areas must be touched up. Another coat of amalgam is applied to the image, but it is done much more quickly this time. Soon the image becomes yellow and silver. Quickly, the whole image is recovered with amalgam. As the image is heated with the torch, the gold color begins to show almost immediately. A view of the image midway through the heating process.
During the final stages of the heating process, one can see the second coat covered all of the lacunae. A brass bristle brush is scrubbed against a "soap-nut" to create an oily lather which will act as a lubricant. Vigorously brushing the aura with the brass bristle brush and the lather from the "soap-nut" to polish the details of the swirls around the perimeter. The soap wash is done very intensely and with considerable pressure. The image is, again, cooled in a water bath. The final condition of the image and the aura prior to polishing. The image is polished in an entirely different manner than the aura. It is rubbed with an agate burnishing tool.
