[TheForge] FW: ITC 213 question

[Martin Paietta]

I just recieved a bottle of ITC 213, is it supose to be brown or does it
turn more of a white or gray after firing. I was redoing the ceramic coating
in my forge and it was recommended to me to put a top coat of ITC213 (I know
213 is for metal). When would you put the top coat on? After the base coat
drys, after one fireing, or after all of the firings? 
 
Thanks
Martin
