I suppose the reliefs could have been pressed into undercut grooves, as the classical ones were, but then they'd have to recut the top of the reliefs because of the hammering. They could, actually, press down a slightly domed relief with something soft to expand it inside an undercut. But I see the fit as a little too perfect, and the metal around the relief has not even a hint of being hammered to fit. I did enlarge the image to 200%, and saw a slight fish pattern. This argues for your theory, but I still have doubts. Anything can be cast. |

To carve that relief with the perfect background without making a trench would have required a machine to rout it out. Obviously you are not familiar with the level craftsmanship of the Japanese craftsmen of the 12th through 18th centuries. They did things by hand, that even today machines have not been able to duplicate. -- Abrasha http://www.abrasha.com |

The object in the photo is called a tsuba. It's a handguard for a Japanese sword. I want to find out how a tsuba like this is made. Was it cast, carved, or..? Here's a link to the photo: http://micknewton.smugmug.com/photos/123184715-O.jpg It's just a guess, but I think it was cast, and then more detail was added by hand. BTW, I don't know anything about the tsuba myself. I don't even remember where I found the photo. I just like the design and I'm wondering how it was done. I especially like how they left some of the bamboo stalks unpainted (unleafed?). It makes the design more three dimensional. Does anybody know how it was done, or even have a guess? Theres another technique that may have been used to inlay the gold onto the iron. thisis where the iron is etched to create a rough surface into which the gold is cold pressed with polished steel edged or rounded burnishing tools. Once done it cant be easilyremoved. Idealfor the very fine detail as shown, and doesnt need undercutting like damascening this would need the tsuba maker to have access to acid type liquids . wether this was possible Im not sure. It might work with sea salt in a paste form. That was available in the 12cent. Ive seen this technique being done on spanish small items like cufflinks etc with differnt colour gold foils. The contrast between the black of the patinised iron and the gold is allways stunning.. t Also Ive some samples of this type of japanese work but its on buttons. As a boy I used to spend many hours wandering around our local museum looking at the Japanese metalwork and laquerwork. Remember it still. The iron tsubas would have been forged. If youve ever watched let alone done any iron forging youll see how quick it can be. My guess is that the tsuba was made from a strip, coiled then chased with chisels. holding something like this when chisseling isnt that difficult.if you know how. Changing the subject somewhat, ive a pair of cast chased and guilded early 19th cent french candelabra The chasing and subsequent burnishing can be clearly seen. Then they would have been fire guilded. |

The tsuba isn't a quillion, its function (if anything) is to do with the grip of the hands, not for deflecting blows. |

Just within jewelry traditions, a number of obvious examples of things that cannot be cast occur to me, in terms of not being able to cast an equal quality duplicate: Coins (any numismatist can tell even a good cast copy coin without trouble, from the orignal die struck ones) Mokume granulation Wrought iron (can't cast that fibrous grain structure) filligree. (yeah, you can cast filligree, sort of, but it's never even close to the real thing) Hand engraved finishes or Guilloche/engine turned finishes (you can cast the shape, but again, it never looks the same. Need I go on? I'm just getting started... Peter |

Pour the still liquid mix into any decent jello mold, and voila. Desert. |

Here is a close-up view of the tsuba in my original post: http://micknewton.smugmug.com/photos/123764979-O.jpg And, here are a few more that appear to have been made using similar techniques: http://micknewton.smugmug.com/photos/123541201-O.jpg http://micknewton.smugmug.com/photos/123764988-O.jpg http://micknewton.smugmug.com/photos/123764990-O.jpg This one is a little different. It's a simpler piece, consisting of a nanako background with two small mon (family crests) in gold: http://micknewton.smugmug.com/photos/123541196-O.jpg |
