Wow - it's true: all the tested glazes I could find in the
Clayart archives have been entered, standardized, and a first
level of screening done. Now is the most dangerous time in any
computer project: when a project gives pretty output but hasn't
yet been vetted by real users!
So, take a look at
http://sankey.ws/glazedata.html
see if you can spot any errors or omissions, and let me know of
anything you find that doesn't look right, via Clayart if you
prefer but private email is better.
As I noted from the beginning of the project, the sole purpose of
this dataset is to permit numerical analysis and consistent
searching of glazes, not to replace the archives or other
projects.
My biggest difficulty was glaze names - they were extremely
variable and often not an accurate reflection of what the glaze
actually does. I have standardized names in several respects:
1. when I know the name of the originator of a glaze, I have
used that person's surname in the glaze name,
2. each glaze name includes the colour actually seen by the
tester,
3. each name is unique within this dataset,
4. duplicate glazes have been merged; glazes of very similar
oxide analysis are noted for each, and
5. glazes used as a base for colorants have been named Base,
then each colour test using it is given the full base name
with a colour added.
I should have kept better track of the names used in the archives
to include them for each glaze here, but I goofed on that during
initial entry. So, I've had to go back to add them, and there are
still a lot missing. Let me know the original names of any you
notice. I'll keep trying to systematically fill them in.
Next, formulate the questions you would like to ask concerning
glazes in the set. A proper web interface is under development by
Odin se forward them to Odin so he knows how
to debug his web interface code. Then, it's up to each questioner
to decide how well the question has been answered; failures will
be addressed by Odin or me as appropriate.

Next, formulate the questions you would like to ask concerning
glazes in the set. A proper web interface is under development by
Odin Maxwell, which will let everyone ask questions directly. For
now, let me know the sort of questions you would like it to
answer. I'll run a local query program here to get the answers,
return them, and of course forward them to Odin so he knows how
to debug his web interface code. Then, it's up to each questioner
to decide how well the question has been answered; failures will
be addressed by Odin or me as appropriate.

Hi John
I have looked through the database and it makes a good evening's read! I
know how much you have worked on this, or almost know, and I think it is
really good work. Thank you for your mention of me. The best part of
testing and getting the results out, for myself, is seeing the work being
accessible to anyone who may like to use it. Your database has
complimented my work and wishes and I send many thanks.
Best regards from Alisa in Denmark
