Shugyosha Posted October 24, 2018 Report Posted October 24, 2018 I currently have a kozuka for sale here, which I believe is ko kinko and done in shakudo. A board member kindly pointed out that, due to the brown colour, he thought that it was probably shibuichi. My understanding is that shakudo comes within a range of colours dependent on the recipe and I thought that dark brown, a little off black was a possible for shakudo. Does anyone have any comments? Here's a link to the listing, please let me have your thoughts. Best, John http://www.militaria.co.za/nmb/topic/26873-ko-kinko-kozuka/ Quote
nagamaki - Franco Posted October 24, 2018 Report Posted October 24, 2018 Hello John, Shibuichi can range from being a silvery grayish, to even a silvery grayish/greenish, to a silvery copper brownish, to almost being a charcoal darkish silvery gray. Which could be mistaken for shakudo depending on the lighting. On the other hand shakudo should be black, blackish, sometimes you'll see a dark purplish black, but there's no mistaking that it's a black. Exceptions, for the sake of this conversation not going there. Black. Next to each other there shouldn't be any confusion as to which is which. Thank you. 2 Quote
christianmalterre Posted October 24, 2018 Report Posted October 24, 2018 Hi John hope this helps in your´s request...? Todays Kinko/ Goldsmiths Shakudo in Japan should have a percentuage of about 3-5% of Gold. Muromachi times Shakudo varied between 3-7% Shibuichi is split into following three subs. -shiroshibuichi ( white) 40-50% Cu, 60-50% Ag (resulting into a highgrey to silver colouration after finnish) -namishibuichi ( standard ) 75% Cu, 25% Ag ( 3:1 ) -kuroshishibuichi ( black) 75% Cu, 22% Ag, 3% Au ( the common in latter Edo ) Christian Quote
