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.

The more you want it the less it will make it thru.

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?
