references to photos[edit]

Intro -- can't just say "upper photograph" and "lower photograph" -- the text needs to be readable independent of illustrations, and editing of article may change orientation of photos versus flow of text.

If images are essential to text description, can do:

' (See illustration 1.1.) '

Or:

' ... as shown in illustration "Coke production" at upper left ... '

(with photos labeled accordingly).

But normally for Wikipedia, an essential image would be in the main text column (a chart for example), and images in the right column serve as non-essential illustrations, explained independently by their captions./ —The preceding unsigned comment was added by 75.6.244.7 (talk) 21:41, 9 January 2007 (UTC).

origins?[edit]

whats the basis for the history section? i have a strong source that contends that coke was first used in postclassical china. Snail Doom 02:41, 25 October 2007 (UTC)

I just added two sentences about Chinese coke use. My source may be the same as yours - why did you not edit the entry using your source? --132.60.240.81 (talk) 18:17, 5 January 2010 (UTC)

The article on the history of iron working mentions the following "However, by this time the Chinese had figured out how to use bituminous coke to replace the use of charcoal, and with this switch in resources many acres of prime timberland in China were spared.[38] This switch in resources from charcoal to coal was pioneered in Roman Britain by the 2nd century AD, although it was also practised in the continental Rhineland at the time.[39]" ( http://en.wikipedia.org/wiki/Iron_working#China )

Within context, the quote appears to contradict that coke was first used in China. 91.176.185.119 (talk) 19:07, 21 October 2010 (UTC)

style[edit]

This article gets too technical too quickly. The information needs to be put in a more sensible order, with the less technical stuff at the beginning of the article, or of individual sections. Maybe I'll get round to doing this myself.--Publunch (talk) 07:51, 28 November 2008 (UTC)

I agree. I cant follow it. Someone with more knowledge than me needs to write, in Plain English, why Coke is/was developed from coal, and what its advantages and uses were, and maybe how much coal is/was used for this purpose. A simple list of the by-products of this process would be great. 122.57.237.82 (talk) —Preceding undated comment added 09:46, 11 June 2009 (UTC).

I agree with the idea of including a more plain-english explanation of the product, history, and significance of coke towards the beginning of the article. I know one good source for such information is the television series Connections by James Burke. I'm looking for a copy of this, or a transcript to use in my editing. -Verdatum (talk) 22:44, 7 November 2010 (UTC)

Poor details on coke as "fuel"[edit]

This and other related articles mention that coke is "used as a fuel." But there are absolutely no details given. WHAT is it used to fuel? When is it used as a fuel instead of other types of coal? How much is used per year? What industries and which countries use the most coke for fuel? These and all other details seem to be omitted. In an article entitled "coke(fuel)," one would hope to read about how and when coke is used as a fuel. —Preceding unsigned comment added by 69.127.200.152 (talk) 06:00, 6 December 2009 (UTC)

There is no mention of coke as a domestic fuel. In my middle-class childhood in the 1950s/1960s we had a coke heater - they were moderately common in our Australian (Victorian) country town. I believe this is also true of UK, at least in parts. 121.219.109.145 (talk) 07:17, 28 May 2010 (UTC)

Agree. Still not mentioned in the lede. And nothing in he lede about steel!? For example: Crucible steel.
"The lead serves both as an introduction to the article and as a summary of its most important aspects. The lead should be able to stand alone as a concise overview of the article. It should define the topic, establish context, explain why the subject is interesting or notable, and summarize the most important points—..." Wikipedia:Manual of Style (lead section)

Agree. I came here looking for info on coke combustion temps when used as domestic heating fuel. Apparently one needs stoves that tolerate a higher temp than wood burning because coke can melt the iron stove itself (source: norwegian wikipedia article on coke). Looking for info on domestic coke-burning ovens/stoves. 31.45.110.132 (talk) 07:59, 5 July 2013 (UTC)

History[edit]

A citation is needed for the claim that coke was used to make malt in 1642. And frankly, I'd be surprised (though delighted) if one can be found. Zythophile (talk) 12:51, 29 November 2011 (UTC)

Easily pleased, then! --Old Moonraker (talk) 13:45, 29 November 2011 (UTC)

chem expert?[edit]

I'm not sure why this article needs an expert in chemistry. I would consider myself an expert in some aspects of chemistry, but, like most chemists, I don't specialize in coke production. The production sections seems to read fine, but I don't know the details about coke production.

On a separate note, I do hope that someone who knows more about coke could expand this article. I read it because I wanted to know about the burning properties of coke as compared to coal or charcoal. What temperature does it burn at? All this article says is that it can burn without producing smoke, but I was under the impression that it also burned at a higher temperature than coal. Also, are there any other ways of making coke? I had heard that blacksmiths had other methods of converting coal into coke in order to achieve higher temperatures. Does anyone know? Lastly, is the history correct? I would have thought that coke had been used much earlier. --El Zarco 11:46, 12 November 2012 (UTC)

simplify intro[edit]

You can tell this was written by an expert, that is, someone who will get nothing across to a novice. And who is looking up coke? Not an expert! The content in the body is fine, but the intro would intimidate a novice. "derived from"!, how about "made from"? You can derive it later in the body of the article. I have a degree in engineering (mechanical), and it blew me away. I started trying to simplify, but gave up.

The intro should mention that it's made from coal and it's primary use, which is iron smelting (I think). Pb8bije6a7b6a3w (talk) 03:02, 19 April 2013 (UTC)

Other processes[edit]

The Other processes section references petroleum coke having use in the manufacture of dry cells and electrodes which are not substantiated on the pages referenced. Can the author provide reference to disambiguate the contribution? I would question whether the contribution is appropriate on the Carbon Coke page as it would be more appropriate on the petroleum coke page. — Preceding unsigned comment added by Fuzzytek (talkcontribs) 03:42, 16 June 2013 (UTC)
