Anyone who posts a glaze recipe on the list, PLEASE PLEASE PLEASE ALWAYS
include the cone. There were two purple glaze recipes posted today, in
response to a question yesterday, but if a person did not note the cone
yesterday they would be out of luck today, because neither recipe included
the cone. This has been mentioned before on clayart, and I really wish the
listserv would simply return any recipe posting which does not include the cone.
Sorry to be so grumpy, but this has been a real peeve of mine.

Along with the cone, it would be
helpful to mention whether the
glaze is suitable for oxidation
or reduction or both.

There have been several recent comments about glaze recipes lacking cone
number, firing type, etc. This is also a pet peeve of mine.
May I suggest using at the very least the GlazeBase simple text format
(the format used on the web) for glazes? Using that format will allow
direct importing of recipes posted to the ClayArt database. Recipes can
also be imported directly into HyperGlaze and GlazChem from this simple
text format. HyperGlaze directly exports to this format also (as may
GlazChem - Bob?) to make posting glazes to ClayArt easy.
The basic format involves labeling each part of the glaze with a heading
followed by a colon ":" so that the software knows which number is the
cone, what part is the name of the glaze, recipe list, etc.
Here's a VERY simple version with the headings for for the basic minimum
amount of information for a glaze recipe:
glaze name:
cone:
color:
surface:
firing:
recipe:
(ingredient amount - list)
comments:
(add pertinent comments here - please add as much as you know about this
glaze and it's use, compatibility with other glazes, clay bodies, etc.)
A filled in sample of the above might be this recently posted recipe:
glaze name: I of Toad
cone: 9-10
color: green to blue-green
surface: textured matte
firing: ox. or red.
recipe:
Kona F-4 (soda) Feldspar 40
EPK (kaolin) 20
Talc 20
Dolomite 20
Cobalt oxide 1
Chrome oxide 1
Granular rutile 20
comments:
This fires to a green matt (some say blue-green) with a lot of texture. It
benefits from slow cooling, combines well with other matt and glossy
glazes,
and gets running if fired above cone 11.

------
More could be said in the comments above about such things as the clay
body used to get the typical result, etc. This will make the recipe MUCH
more useful when someone retrieves it from the ClayArt glaze database
archives.
Better yet, post a fully documented recipe to the GlazeBase site at:
http://www.tiac.net/users/rjw/gbpage.htm
I hope this may help people to post adequately documented recipes on
ClayArt.
Thanks,
Richard
