Nil and Gavin both posted good discussions
on the issue of element degradation using ITC coating.
I think there are one more thing we need to clarify.
ITC 100 and ITC 213 coating are designed for different
purpose. ITC 213 is specially designed to prevent oxidation
and erosion and ITC 100 is for energy saving and refractory
protection. Two different products with two different purposes.
Nil's experiement was using ITC 213, and it worked. And it
is the recommendation of ITC to use ITC 213 . I am not
sure what coating material other people used.
Regarding Nil's comments on people are giving mis-leading
information without experiments, I think we need to understand
how and why things work. There are two approaches to science.
One is to use experiment to FIND the theory, and the other
is to use the experiment to PROVE the theory. One is inductive,
and the other is dedective. The discussion I started on the
degradation of element was hope to bring some insights on how
things work so we can have higher chance of success when we
do the experiment. I think the key point here is understanding
through discussion. And it's important that people
support their statement with either experimental results (like Nil
did) OR some theoretical understanding (like Gavin did).
I find Clayart is a great place to bring up discussion like this.
Hope no one is getting upset over this.
sincerely,
Gary Wang
