Thanks Bill, Application is exactly what I'm worried about. Your experience
certainly gives me something to think about. I've never heard of APM
elements before. Will definitely look into that.

Hi all,
I need to put new elements in my kiln soon and am wondering what experience=

anyone has had using ITC 213 coating. My elements are going to cost almost
$600 so if I can make them last twice as long it could be worth it. I recal=

that Mel puts the ITC on by dipping but am wondering how that could work if
I only buy a pint. Has anyone applied it another way? Have you found it to
extend the life of the elements? Thanks for any information!

ITC will work on your elements, but you damn well better be sure it is
applied correctly. It needs to go on THIN! Almost to the point you can't se=

it.
I tried it a few years back and thought I was doing good with the
application, but found out I was applying too thick. I fired the elements i=
n
a kiln to just red heat to burn off any production oils. Others use bleach
to remove the oil. I mixed ITC 50/50 with water, put in drywall compound
trough, ran elements through, avoided getting on pigtails, hung up to dry.
Installed, fired kiln empty, got lots of black particles in kiln. Fired wel=
l
for several firings, then elements began shorting out. One even burned
through an element holder. It was me, application too thick.
Had an Axner Super Kiln (Olympic) that had ITC on elements. Not sure if
elements lasted longer with ITC or not, but I did have to replace elements
after 2 years in school setting.
If you are installing APM elements, I don't think you may need the ITC.

Lis,
Check this Kanthal site for detailed information:

y/>
They are different from the usual A1elements in both composition and
manufacture. In my instance, I have gotten 60+ ^6 crystalline glaze firings
so far without any change in programmed firing schedules. I would usually
get about 40 of these type firings with the usual A1 elements.
Yes, they are more expensive.

Janet, I used the ITC on my new elements and applied the material by
brushing with a 2" sized paint brush after they were installed. The only
failure I have had with my elements was when one burned out when an =3D
external
connecting wire shorted outside of the kiln. I sure hated to lose that
element, because they are very expensive, especially on a large kiln. =3D
For
some reason the electrician removed the element even though I think it =3D
could
have been hooked up again.=3D20
As I didn't want to handle the spray system of application of ITC to my =3D
kiln
interior, I brushed that on as well. So far everything is holding up =3D
very
well.

Hi Janet,
Running a kiln vent will extend the life of elements.

Thanks everyone for the info. I have yet to hear from anyone who has used
the ITC and noticed a significant improvement in element life. According to
Euclids the APM elements are 4 times the cost and haven't been found to
yield the proportionate life.

That is probably true. APM elements make sense when the kiln is firing
expensive ware that would be ruined if the kiln had to shut down to due
an element failure. The only example that comes to mind is large glass
crucibles.
