[QUOTE="Car 54, post: 199420, member: 85"] With some porcelains the cte can also change over multiple firings. On a single that you just do your normal opaque, build and glaze, probably won't be a issue. But if you have to do multiple firings on a bridge, the cte can change and need to do a slow cool. That is why I like Vintage Halo, it's stable over multiple firings, I used to have more cracking issues with Vintage, when I had to run it multiple times. [/QUOTE]
