Nice pictures, iannon.
The network shows much more faint over here. I take it you have been drinking mostly other teas than sencha in yours?
My "SnowDrift" is nowhere near this yet, but I'm working on it as we speak
On SnowDrift's glaze, the network of crackles is very "tightly knit".
The Seigan "Tempest" SO on ther other hand, has comparatively large unaffected areas between the darker lines (which oddly have a slightly pink, not brownish, tint here, Sencha and Gyokuro being the only teas I've used it with).
