325 will flux (melt better)I gave up 200 decades ago.
Allowing your 1st glaze to dry completly will help with any double dipping.
Cobalt glazes are notorious for crawling. I know thats not your issue-your glaze has no clay in it to make it stick.So in the big picture it may be your issue.
I have no idea why your calcining zinc?
This is usually done to epk so it does not shrink to much and flake off.

I do not think the 200 mesh to 325 will do a thing to your flaking
You have such a high % of feldspar and silica and so many colorants this is bound to get powdery with no clay to stick it.
All I can add is what did you do different?

I do run my lights lot so half the cost makes sense to me.Since retrofiting is so easy-thats why I'm posting this energy saver. They also run cool compared to ballast lights.Another asspect is outside in cold weather they do not flicker at all.

I once knew a potter who used the libby ones with thrown stems and E-6000 glue for the glass. I am not a wine drinker but always thought wine was best in glass over ceramic goblets.Are you wholesaling these goblets?
