Dear Colin Durie,

Do you mean melting temperature, that is, the fusion point?

Or are you interested in the Heats of Formation of these oxides, that is =
the Standard Free Energy of Formation and the Standard Heat of Formation =
of each of the oxides?

I have references for each.

Best regards,

Dear Bill Aycock,

You say <although it's the same thing.>>

This is the amount of energy in joules or calories which will convert a =
solid to a liquid without alteration of temperature. Are you sure this, =
usually called "Latent Heat of Fusion" is what is required?

Best regards,

Ivor Lewis. Redhill, South Australia.

Dear Colin,

I wonder if you're aware of the glaze programs
already on the market? Not to say that you can't
write something better, but if you haven't done
so, you might take a look at them and see where
you feel improvements need to be made. Just do an
internet search. Most of them offer on-line
download and a free trial period.

Best wishes with your project.

Ivor
I really think the original questioner is confused in his terminology of
what he wants. It looks like he is confusing "heat" with "temperature". I
could be wrong. If he meant "temperature", that indicates he is trying to
predict glaze melting, which is going to be difficult, considering the
solution and eutectic processes he will encounter.

In my reference (CRC), "Latent heat of Fusion" is indexed under "Heat of
Fusion", for simpler location with other heat terms. You are right about
the term, but i did say "listed as".

Bill
