Refractory coating

And this folks is what is known as a troll.

Good luck with your casting work buddy. You have found a very small corner of the world and acting like an ass wont win you any brownie points. If you wanna pull this kind of nonsense, I suggest you find the casting section over on https://www.iforgeiron.com/
There are plenty of assholes there, you'll be in good company. The home foundry has nothing but nice guys here willing to help people.

 

Not yet. Been super busy lately. It’s definitely noticeable just with it on there as is. How hard is it supposed to get after firing it?

 

We will only know that after you fire it since you are the first one here to use that coating. Let us know.
