Greetings all,

Does anyone know of a source for Molybdenum oxide and has anyone ever used
it as a glaze material?

No but molly typically occurs in nature as a sulfide Molybdenite -MoS2. I
believe it is used as a lubricant because it is a soft metallic, greasy
feeling material. Maybe you could just spray it on a pot like the old
galena (lead sulfide) glazes. I'm sure the oxide would be available from
the chemical supply houses but it may be pricey.

One of the best chemical supply houses I know of is J.T. BAKER. Try "800"
information to get their phone number.

Their chemicals are very pure -- they carry reagent quality goods (VERY
$$$!). What I like about them is you KNOW what you're getting.
Essentially every "oxide" and element is available -- this is a "real" lab
supply.

Should you find "moly," do let us know what it does? Thanks!

Ellen mentioned J.T. Baker--

JT Baker chemicals are sold by Mallinckrodt Baker Inc ---
www.mallbaker.com. Or 1-800-jtbaker. For small qualtities it may be
suggested to get them through one of their distributors.

Greetings Ron Roy: You were asking about Molybdic Oxide or Molybdenum
a while back. Rick Mahaffey responded and is correct that it usually
provides a silvery color. He mentioned Herbert Sanders and I happened
to deliver one of his pots for an exhibit this week. It is
silver-blue with amber crystals, fired to ^9 in a electric [Globar]
kiln. Sanders9 text, Glazes for Special Effects mentions molybdenum
for crystals on page 42. Most were fired to ^9. MnO3 also vaporizes
and can have effects on other glazes. For crystals, try in
combination with titanium oxide of rutile. It also adds gold color to
low-temperature lusters. HS explains this on p 108.
I experimented with it in the 509s and still have some formulas but I
fritted my base glaze before adding molydenum and Venadium. I9ll be
glad to share them with you if you like. Mine ware not crystals, more
an eggshell white. Great to experiment with Mn03. RS
