message: With the very occasional exception glass, and even frit, have not been used to produce soft paste porcelain for 100s of years.

*Everybody started using a blend of hard-paste after WWII. Asian clay was abundant and easy to find now that the Pacific rim was open to the Western world. There are even prepackaged blends of porcelain sold by by the ton by major manufacturers - JUST LIKE COFFEE! --Emana 21:12, 27 February 2006 (UTC)

message: Tellyaddict: please do not delete this contribution again. The comment about the stub is to highlight a mistake: soft paste porcelain china is far more widespread a subject than to be covered by a single, art dedicated stub. The subject is diverse, and covers areas including antiques, industry, art and materials science

message: Hello all,
Recent changes have been
*“constituent materials were not widely available in the west” -> “before the constituent materials were widely available in the West.”
*“Because of its low firing temperatures and chemical composition, soft-paste porcelain posesses certain characteristics that are unique” -> The lower firing temperatures of oft-paste porcelain compared to Hard paste porcelain gives Artists and manufacturers some benefits, including a wider palette of colours for decoration and reduced fuel consumption
*Changed “The body is granular because the ingredients do not meld together unlike hard-paste porcelain.” To reference glass formation
*Removal of “Therefore, water and other water-based substances (mainly paint) will permeate the body. This causes difficulty when applying flat colors to the body, of course unless an uneven mottled finish is desired. Therefore, applying a glaze is a simple and popular solution. Sometimes glaze is used on other ceramics to mimic products made using soft-paste porcelain.” I guess some will say I was harsh, but this statement suggests that soft-paste porcelain is not vitreous, which by definition it must be.
:Theriac, Yes, all porcelain is vitreous to a certain degree, but soft-paste, because of its inherent softness, must be fired at lower temperatures. Therefore, the body is MORE granular than that of hard-paste porcelain that has been fired at higher temperatures. It is one of the reasons that glazing was so popular on soft bodies. Could you suggest a rewrite instead of a total removal? -- Emana 20:22, 12 January 2007 (UTC)

message: Hello Emana
I am unclear about your statement “technically correct in pointing out that what we call "soft-paste porcelain" today is not really porcelain.” Could you explain why not? And why is calling it so “a misconception?”
ThanxTheriac 13:44, 12 January 2007 (UTC)
replies: text: Theriac, sorry. I was trying to defend you against an NPOV inquiry by another user. The misconception is that soft-paste "porecelain" is a misnomer that has survived the centuries. Like the sea cucumber is not a cucumber, the first people who named this substance should have picked a different name.
Hello Emana,
Thank you for the reply. I was a little unsure about the comment as soft-paste compositions are certainly porcelain.ThanxTheriac 13:15, 15 January 2007 (UTC)
thread_title: Notes on "misconception"

message: Hello Marshall46,
Thank you for the reply, and I hope you earlier response about “making and decoration.” With reference to your comment on temperature if it is to be included, and I am not sure if it would be advisable, it should note “up to 1400oC for hard paste” and for soft-paste it would be “up to 1250oC” I can see value in a historic section, and suggest that the different types of soft-paste are included, such as frit porcelain and feldspathic porcelain.ThanxTheriac 13:44, 12 January 2007 (UTC)
replies: text: How about explaining why this substance is considered "soft" in the first place. When I got hit in the face with a soft ball, the first thing I thought was that it wasn't soft at all. Then I got hit in the face with a baseball and found out that it was indeed harder. -- Emana 20:22, 12 January 2007 (UTC)

text: Hello Marshall46, Pyroplasticity is the recognised term for the phenomena. Providing there is an appropriate explanation for anyone who does not it I can see more value in leaving than removing it.ThanxTheriac 13:25, 15 January 2007 (UTC)
replies: text:  I think "pyroplasticity" is an introductory level industry word that will encourage readers to read-on. Like the word "punt" for football makes readers think they understand a little bit about the game. -- Emana 18:57, 15 January 2007 (UTC)
replies: text: Hello Emana, thanks for the comment. I would agree that "pyroplasticity" may also encourage further reading. Similarly other technical terms could be used, with appropriate explanation or links to other pages. I'm not sure I understand your "punt" analogy. Is this American fottball or proper football :-)Theriac 19:15, 15 January 2007 (UTC)

text: Ah, American football that is. Again, one of those things that the founders should have named differently. -- Emana 23:16, 15 January 2007 (UTC)
thread_title: Making and decoration

message: I have heard of "lower fuel consumption" as an argument that manufacturers use to choose to fire at lower temperatures of any ceramic. But is this why they would choose soft-paste over hard-paste? I guess it is a side-benefit of it. It would be interesting to see if there are any side-by-side research on it. BTW, hard-paste can still be fired at lower temperatures to form less vitreous bodies for glazing and paiting in the classic European style. I read somewhere that M.I. Hummel does that now. -- Emana 20:47, 12 January 2007 (UTC)

:Great! The book, English Ceramics, by George Savage seems to have been thrown around several publishers. Can you include the edition and publisher for the bibliography? -- Emana 21:33, 12 January 2007 (UTC)
