Talk:Tin-glazing

I have reorganised the article, putting the historical material together at the beginning and the technique after. I have added detail and clarified the glaze formula - it was not correct to put tin-glaze in opposition to lead-glaze, as tin-glaze often contains lead. I have added sources, including Caiger-Smith, whose Tin-Glaze Pottery is the standard work in English. Marshall46 01:24, 7 January 2007 (UTC)

I now have suggested merging this article with Maiolica - see that article for my reasons. Marshall46 14:50, 30 June 2007 (UTC)

Following Wetman's suggestion, I propose not to merge but to link all the articles that refer to tin-glazed pottery through a general article on that topic, which will refer to main articles on detailed aspects such a Hispano-Moresque ware, Delftware and Faience. I have made some changes to this article, which now emphasises the technical aspects of tin-glazing, leaving detailed historical accounts to other articles. I am working on Tin-glazed pottery.Marshall46 16:21, 2 July 2007 (UTC)

Now done. Marshall46 18:14, 5 July 2007 (UTC)

Flint

86.153.170.162 says that flint as a raw material is no longer used. Not so. You will find it in every potters' catalogue. See, for example, Potterycrafts P3319 http://www.potterycrafts.co.uk/extra%20content/generic.asp?GroupID=292&bannerId=233&section=b.a&file=../extra%20content/raw_mat.html#f So I have reverted your edit.

Well as someone who(i) works in the raw material supply industry, (ii) replaced flint for alternatives in a number of formulations, and (iii) works for a supplier to Potterycrafts I can assure you that flint is no longer used. The name is retained by some for those people who do not understand the differences between flint and its alternatives. I have reverted your edit. —Preceding unsigned comment added by 86.147.252.72 (talk) 06:46, 9 July 2008 (UTC)

Welcome to Wikipedia. As a new editor you may like to read the articles on Wikipedia:Verifiability and Wikipedia:No original research. It would be helpful if you signed your edits.

Your objection to the use of the word "flint" seems to be based on your professional experience, which I am afraid is original research. If the material is called "flint" in Alan-Caiger Smith's book and the Potterycrafts catalalogue, then it has to be called "flint" here.

Your change from “A typical modern tin-glaze recipe is given by Alan Caiger-Smith” to “More contemporary tin-glaze recipe by Alan Caiger-Smith is” does not read as well, so I am going to change it back. - Marshall46 (talk) 08:59, 9 July 2008 (UTC)

My change reflects the raw materials that have been used for some time. Accepting that Wikipedia is not interested in the truth or facts I see that "flint" should remain if that is what is listed in Mr. Caiger-Smith's book, but the reference to Potterycrafts is irrelevant as it is not listed in the article (also their description of the chemical formula, SiO2, is, at best, an oversimplification.) It is also noted that flint has never been used in bodies and glazes. The material is calcined flint; a very important distinction. Mr. Caiger-Smith reference to "flint" suggests a lack of technical understanding. Also noted is that calcined flint has not be available for some time. I will slightly modify the article as it is not correct to describe something from a 1973 publication as "contemporary." —Preceding unsigned comment added by 86.159.51.187 (talk) 18:28, 9 July 2008 (UTC)

An alternative is lead-glazing

An alternative is lead-glazing, where the basic glaze is transparent; some types of pottery use both.[2]

Maybe this would be better understood if phrased

An alternative process to coating with tin-glaze then brush-painting with metallic oxide enamel(s) (dip, dry, paint, fire), is painting with translucent coloured lead glazes applied direct to the biscuit, then fired (paint, fire). Some types of pottery use both.[2]

Another option would be

An alternative is decorating with translucent coloured glazes direct to the biscuit. Some types of pottery use both.

As written it sounds as if tin-glaze is something other than normal lead glaze with added tin. Before I make the change, any comments? Davidmadelena (talk) 22:31, 28 October 2019 (UTC)
