Zhpottery-Epi3.2- Three (Actually 4) Glaze Discussions Part 2

Part 2 of a 2 part video.
We start the vid with a quick update on the cleanliness of my garage after today. And get straight into a talk over:

1 Purple Glaze and Some of My Bowls and Smooth Clay Bodies
2 Ash Glazes and C.M.O., Glaze Running On The Shelf, and Some Shrinking Knowledge
3 Luster Shino and Dark Clay Bodies
4 C.M.O. and Porcelain Bodies Plus Color Speculation

Please SUBSCRIBE!
My ultimate goal for the "zhpottery" channel is to provide information, help, tips, and honest opinions on ceramics. I hope to breath a new, fresh set of videos relating to pottery on a daily basis and hopefully building the potters and artists Youtube community which is what helped me pursue ceramics when I was starting with clay.

I have heard of some glazes actually breaking the pots they are on. glazes that are very flux heavy / lots of crazing ( like some ash glazes) Could this be one of these cases? I think that it also has much to do with surface tension / Expansion and contraction ratios of both your glaze and your clay body. That being a porcelain bottle thrown so thinly had me wondering if this might be an expansion and contraction issue being opportunistic of any micro cracking. something to think about.

@tatteredgrey thats a good point, im wondering if not glazing the inside had anything to do with it? but you may have a good point in the shrinkage difference between the clay and glaze, i will look into further, thanks

I am gonna disagree with the assessment that that bottle split because of a glaze run. For a shrinkage split to happen it needs two connection points ie two glaze runs or really messed up shelves. and the crack will be between the two connection points. this crack to me looks like a crack formed while trimming. a piece that was dry. Pushing on a dry piece will cause splits that open up along a weak spot that cannot take the stress. and shows up when it shrinks again(glaze firing)
