Talk:Black gold (Jewelery)

Copyright Violation

Regarding the following section of text:

Electrodeposition using black rhodium or ruthenium is one method. Amorphous carbon is also used
at times, with the Plasma Assisted Chemical Vapour Deposition process. Controlled oxidation of
carat gold containing chromium or cobalt can also be made to yield black gold. Ruthenium
containing, electroplating solutions give a slightly harder black coating as compared to
electroplating solutions that contain rhodium.

Those sentences are taken word-for-word from the first external link, [1]. In accordance with WP:C they should be rewritten or deleted. -- CWesling 01:10, 8 February 2007 (UTC)

Page rename

The person who renamed this from "Black gold (jewelry)" to "Black gold (jewellery)" did not obtain any consensus first and has been warned several times on their talk page about doing this sort of thing. According to the Manual of Style, pages should stay in whichever national variety of English they were started with, so I have moved it back to "Black gold (jewelry)". -- CWesling 02:03, 25 April 2007 (UTC)

POV

"Unfortunately, black gold is very hard and making jewellery out if it usually necessitates using previously-made melting forms. Changing the size, adding stones or other customizations are often too hard for the common goldsmith."

Several issues:

1. I assume, but am not certain, that "out if it" should be "out of it".
2. It is unclear how the "hardness" of black gold "necessitates...". Is this saying that it is fairly immalleable and (in keeping with the POV in the next sentence) its hardness makes it difficult to work with? Are there words missing: "...hard to work with and making..." or "...hard to form and making..." or... If so, this is unsourced POV.
3. Various work is said to be "too hard for the common goldsmith". This states that most goldsmiths lack the skill and/or tools and/or training to work with black gold. POV.
4. I am more than a little confused by the idea that a metal with a finish (whether oxidation or electro-plated) can then be made into jewellery at all without needing to redo the finish.

Actually, a search just now seems to indicate that the paragraph is a copyvio from [2]: "But it is very hard and making jewelry out if it usually necessitates using previously-made melting forms. Changing the size, studded gold with precious stones or other customizations are often too hard for the common goldsmith." vs. "Unfortunately, black gold is very hard and making jewellery out if it usually necessitates using previously-made melting forms. Changing the size, adding stones or other customizations are often too hard for the common goldsmith."

So, with all of that, I am, for the moment at least, removing that paragraph. Mdbrownmsw 12:34, 9 October 2007 (UTC)

Fair enough. After leaving that question on your talk page, I realized that paragraph was probably what you were referring to, but I didn't have a chance to work on it, nor did I realize it was a copyvio -- good catch. Not surprising, though, this entire article started out as a direct copy of text from another website, as you can see in the history. I've been collecting some informational links about black gold, so one of these days I'll expand this a bit and add citations. -- CWesling 07:38, 3 November 2007 (UTC)
