Scheele's Green not the first to contain arsenic

I removed the claim that "Scheele's green was the first pigment to contain arsenic". Even though the reference claims that this is true, arsenic pigments such as Orpiment have been used since at least the middle ages. See for example pg 176 of "The Materials and Techniques of Medieval Painting" by Daniel V. Thompson and published by Dover in 1956.

Perhaps a different claim was meant, such as "Scheele's green was the first synthetic pigment to contain arsenic" or that "Scheele's green was the first green pigment to contain arsenic" but arsenic pigments for painting and glassmaking are well known from before the middle ages.

It is a tragedy for an article about a pigment color not to have any actual color represented on the page. ForumRoleplay (talk) 21:53, 4 March 2016 (UTC)[reply]

How the hell you gonna have an article about a pigment color without having any pictures of the color?

I don't understand. — Preceding unsigned comment added by 205.133.192.85 (talk) 18:43, 14 September 2019 (UTC)[reply]

I came here to say the exact same thing. Like if the Rainbow page thought it was gauche to actually have a photo. -82.1.109.96 (talk) 20:39, 14 September 2019 (UTC)[reply]

According to this article, the following image File:Fashions_for_May_1868,_Plate_1,.jpg is of a dress of the right color, but a better source seems to be needed. sverdrup (talk) 21:17, 14 September 2019 (UTC)[reply]

It is a challenge to find a copyright-free image of a pigment that has not been used for so long. Normally one can just find some of the pigment and take a picture of it. I'm looking for one though. — Preceding unsigned comment added by Born2clone (talk • contribs) 05:59, 27 September 2022 (UTC) Note that there is a color coordinate based example of the color of the pigment, and to call attention to it (as I have to admit I didn't see it at first either) I modified the text of the first paragraph to note the hex code for the color. It is possible, because of the instability of the pigment, that the color coordinates provide a better indication of the color of the pigment when as it was used in the 19th century, over photos of pigment taken today after over a century of aging. — Preceding unsigned comment added by Born2clone (talk • contribs) 07:19, 27 September 2022 (UTC)[reply]

Poorly Written

First paragraph: "which in the past was used in some paints, but has since..." Really?? "In the past"?? Which past? What if I read this in 2019? The past is 1995. Then? What if I read this in 2179? Maybe it was used up until 2019?? "Has since..."?? Same deal! 978 BC? 2020 AD?? PS: I came here to read about it being toxic and killing people. It should say so upfront center... in THE FIRST FEW LINES! — Preceding unsigned comment added by 108.178.137.210 (talk) 03:17, 11 November 2019 (UTC)[reply]


I modified the first paragraph to include many of the details requested, specifically the time frame of it's use (early to mid 19th century) and the decline in its use after the 1860's. — Preceding unsigned comment added by Born2clone (talk • contribs) 07:11, 27 September 2022 (UTC)[reply]
