Cave in.
Under-glaze red is traditional famous and precious glaze kind, first imposes one layer of ground-coat enamel on porcelain body, then with copper oxide as major colorants
Depicting pattern decorative pattern on porcelain body, then impose cover-coat enamel, by bivalence copper reduction under strongly reducing atmosphere under 1250～1280 DEG C of high temperature
Become monovalence copper, assume the red decorative pattern blushing like a peony.Why under-glaze red needs applying two-layer glaze to be because cover-coat enamel at high temperature
Form liquid phase cover layer, this layer of cover layer can stop the monovalence copper in colorant from being reoxidized into cupric, it is to avoid occurs
Glaze paint is in green；And ground-coat enamel can stop colorant and base substrate directly contact, under the high temperature conditions, the sintering of base substrate lags behind glaze,
When ground-coat enamel burns till liquid phase, base substrate is still in initial stage of sintering, mid-term, and not yet a large amount of liquid phases occur, and there is connection pore, ground-coat enamel
Presence can stop oxidizing atmosphere from passing through the cu in colorant from base substrate2O carries out selective oxidation and becomes cuo, it is to avoid red glaze paint
Obfuscation, therefore, two-layer glaze is indispensable.
