Dear Friends,=20
Some of you may find useful information in this text.
Editor, G. V. Samsonov, "The Oxide Handbook" 1973. ISBN 0-306-65157-2.
Very expensive (if I wished to get a copy) but should be available in =
State Reference or major University Libraries. Over 500 pages.
Extract of interest for those working with Copper Glazes on pp 214-215 =
under the heading " ll Thermal and Thermodynamic Properties, 24 Thermal =
Stability Characteristics
"29 Cu2O Unstable below 375 deg C and decomposes to CuO and Cu. Stable =
on heating in air only above 1070 deg C. Oxidation to cupric oxide =
begins below this temperature. Converted almost completely into CuO with =
prolonged calcination above 800 deg C. Melts without decomposition. =
Appreciable decomposition above 1800 deg C.
CuO. Unstable compound, decomposes appreciably beginning at 800 deg C, =
decomposes completely in pure oxygen at 1100 deg C. Quite stable to =
heating: decomposes to Cu2O and oxygen begins only at about 1000 deg C =
(oxygen pressure if 1.013*10^5 N/m^2 reached at 1110 deg C)

CuO at 400 deg C.
CuO2 Unstable; decomposes completely to CuO even in oxygen atmosphere at =
100-150 deg C"
Looking at some of the other oxides common to studio ceramic practice is =
also enlightening. Some entries show that we should be cautious about =
our belief that many compounds decompose leaving oxide residues.

Ivor,
I have been looking for The Oxide Handbook to add to my personal library
for some time. If you or anyone else for that matter knows where I could
obtain a copy please contact me offline. Thanks.

Dear Lily,
I do not know where you are but I have a contact www.bookfound.com or =
you can e-mail at search@bookfound.com=20
We have used them a couple of times. They give a good service at cost we =
can afford.
I will not be competing against you for this one. Though it is =
comprehensive and very thorough I don't thing there is sufficient =
information for the average Jack or Jill Potter. For example; the table =
for Linear Coefficients of Thermal Expansion has nothing to say about =
the Alkali Metal Oxides though it does give values for CaO, MgO,SiO2.and =
Al2O3.
I will do the usual with the few pages I need.. As I said, it's a pricey =
book.
Best regards,
Ivor
