By the above-mentioned description of this invention it is found that relative to the prior art, the following advantageous effect of the invention having：
1st, in the first technical solution and based in the other technologies scheme of the first technical solution, snowflake glaze glaze includes overglaze
Glaze and ground-coat enamel glaze, and overglaze glaze uses marzacotto, ground-coat enamel glaze uses milkiness white glaze material, is stood in this way to be formed to have
The snowflake line for not floating on surface of body-sensing provides base substance condition.What is more important, by the initial melting temperature of overglaze glaze
35-45 DEG C of the initial melting temperature of ground-coat enamel glaze is set at less than, can be caused in sintering process, the lower melting-point cover coat that begins is first
It is melted in ground glaze layer, and is tightly attached at the ground-coat enamel layer surface not softened completely, and then promote the melting of ground glaze layer, reduce bottom
Glaze layer side interface fusing point and viscosity, so as to which ground glaze layer be enable to carry out with cover coat the melt composition between interface in advance
It exchanges, makes to form chemical analysis circle between ground-coat enamel and overglaze by exchanging chemical analysis on ground glaze layer and cover coat interface
Middle layer, and during this, the quartz crystal of infusibility, crystal of zirconium oxide etc. are then in above-mentioned melt exchange process in ground glaze layer
Irregular flakes is gradually showed, and continues to wedge cover coat bottom, has been eventually formed with certain relief snowflake
Line, this snowflake line is located at the bottom of transparent cover coat, therefore it does not float on the surface of cover coat and glaze paint glossiness is good, reflection
Light is soft, produces good visual effect.The initial melting temperature for setting overglaze glaze is less than the initial melting temperature 35- of ground-coat enamel glaze
45 DEG C, be because if initial melting temperature difference between the two is higher than 45 DEG C, then cover coat meeting burning, causes glaze paint to tarnish
And easy soil pick-up；And if initial melting temperature difference between the two less than 35 DEG C, can cause snowflake line formed it is unintelligible very
It can not extremely be formed.
2nd, in the second technical solution, the initial melting temperature of ground-coat enamel glaze is selected between 1155-1175 DEG C, then is burnt into temperature
Degree can be controlled at 1230-1250 DEG C, and medium temperature firing can be energy saving.And by calcium oxide content control in 13-15%, by oxygen
Change the control of the sum of potassium and sodium oxide content less than or equal to 3%, then with the calcium of conventional self-cleaning glaze, easy clean glaze or clear frit
Content (generally in 10-12%) and potassium sodium content (generally more than 3%) are different, and main purpose is to reduce overglaze glaze
The initial melting temperature of material so as to be conducive to form middle layer between cover coat bottom and ground-coat enamel layer surface, reaches to form three-dimensional sense
The effect of snowflake line.And calcium oxide content and relatively low potassium oxide, sodium oxide content higher in overglaze glaze can also promote
Cover coat forms more calcium and magnesium glass phases, is formed simultaneously less simple glass phase, since calcium and magnesium glass phase hardness is compared with potassium sodium
Glass is mutually high, therefore makes cover coat more resistant more resistant to corrosion.It is because if oxygen that 15%, which is selected, as the upper limit of calcium oxide content
Change calcium content is excessively high, and the fusing point that begins is too low, the easy burning of cover coat；Select 13% as calcium oxide content lower limit be because if
Calcium oxide content is too low, and the fusing point that begins is excessively high, and the snowflake line of formation is unintelligible.
3rd, third technical solution is a preferred embodiment of the second technical solution, this preferred embodiment biggest advantage
It is due to the high magnesium of high calcium, high temperature viscometrics are low at high operating temperatures and surface tension is high for overglaze, and the overglaze glaze of the embodiment melts length
Up to 9-11cm, and the molten length of common overglaze glaze only has 7-8cm, and indirect reaction high temperature viscometrics are low, and simultaneously in the embodiment
Overglaze frit surface tension reaches 381dyn/cm2, and the surface tension of common overglaze glaze generally only has 374dyn/cm2.Due to
The high temperature viscometrics of the overglaze are low, and so that the glass that surface is formed mutually melts, effect is more preferable, and glaze paint is more flat, and the surface of glaze paint is thick
Rugosity is lower, is less susceptible to pickup, and since the surface tension of the overglaze is high, the micropore formed in pyroprocess is few,
The soil pick-up of glaze paint is caused to count to reduce.Meanwhile strontium oxide strontia is added in overglaze glaze, be conducive to improve the lustrous surface of glaze paint
Degree.And contain silver oxide in overglaze glaze, be conducive to antibacterial.
4th, the 4th technical solution and the 5th technical solution are two of the ground-coat enamel glaze of milkiness white glaze property preferred real respectively
Example is applied, wherein the ground-coat enamel glaze initial melting temperature of the 4th technical solution ground-coat enamel glaze in 1165 DEG C or so, the 5th technical solution
Initial melting temperature can coordinate between 1170-1175 DEG C with overglaze glaze, form middle layer and snowflake line.
5th, the 6th technical solution discloses the preparation method of snowflake glaze, and wherein ground glaze layer thickness control is in 0.5-0.7mm, face
Glazed thickness is in 0.1-0.15mm.Wherein, if overglaze layer thickness is less than 0.1mm, can cause in sintering process, ground glaze layer
Cover coat is fully absorbed into melting, middle layer can not be formed and there is relief snowflake line under transparent cover coat；And
If cover coat is higher than 0.15mm, it can cause cover coat that ground glaze layer is fully absorbed melting, can not also form middle layer and position
There is relief snowflake line under transparent cover coat.
6th, the 7th technical solution discloses the method that overglaze formula is adjusted according to ground-coat enamel glaze.In fact, this patent Shen
Please in can be can have wider range of choice as the ground-coat enamel glaze of snowflake glaze glaze, it is important to how to realize using as
The overglaze glaze of marzacotto and the matching of ground-coat enamel glaze, this matched key is initial melting temperature difference, in order to reach regulation
35-45 DEG C of initial melting temperature difference, the 7th technical solution discloses the specific method for adjusting above-mentioned initial melting temperature difference, that is, adjusts
The relative amount of calcium oxide in whole face glaze glaze, if calcium oxide relative amount is higher, the initial melting temperature of overglaze glaze is lower,

Table 2：The embodiment of experiment two and the relationship of comparative example overglaze glazed thickness and snowflake line
From experiment one above and experiment two：
First, overglaze initial melting temperature and the difference of ground-coat enamel initial melting temperature are to form the key factor of snowflake line.Begin in overglaze molten
When temperature is less than 35-45 DEG C of ground-coat enamel initial melting temperature, ideal snowflake line, if difference is too small, snowflake line can be formed
It can not be formed or unobvious, if difference is excessive, the easy burning of cover coat.
It, can be with this is because the initial melting temperature of overglaze glaze to be set at less than to 35-45 DEG C of the initial melting temperature of ground-coat enamel glaze
So that in sintering process, the lower melting-point cover coat that begins melts, and be tightly attached at the bottom not softened completely prior to ground glaze layer
Glaze layer surface, and then promote the melting of ground glaze layer, fusing point and viscosity of the ground glaze layer side in interface are reduced, so as to make ground-coat enamel
The melt composition that layer can in advance carry out between interface with cover coat exchanges, and makes on ground glaze layer and cover coat interface by exchanging chemistry
Composition forms middle layer of chemical analysis circle between ground-coat enamel and overglaze, and during this, the quartz of infusibility in ground glaze layer
Crystal, crystal of zirconium oxide etc. then gradually show irregular flakes, and continue wedging surface in above-mentioned melt exchange process
Glaze layer bottom has eventually formed and has been located at the bottom of transparent cover coat with centainly relief snowflake line, this snowflake line, therefore
It does not float on the surface of cover coat and glaze paint glossiness is good, and reflection light is soft, produces good visual effect.Set overglaze
The initial melting temperature of glaze is less than 35-45 DEG C of the initial melting temperature of ground-coat enamel glaze, is the initial melting temperature difference because if between the two
Higher than 45 DEG C, then cover coat can burning, glaze paint is caused to tarnish and easy soil pick-up；And if initial melting temperature between the two is poor
Value can then cause snowflake line to be formed unintelligible or even can not be formed less than 35 DEG C.
2nd, in the case where meeting above-mentioned condition, the content by adjusting calcium oxide in overglaze glaze can adjust overglaze
The initial melting temperature of glaze, calcium oxide content is higher, and the initial melting temperature of overglaze glaze is lower.Potassium oxide and sodium oxide molybdena should be contained simultaneously
Amount control is below 3%.
By calcium oxide content control in 13-15%, by the control of the sum of potassium oxide and sodium oxide content less than or equal to
3%, then the calcium content (generally in 10-12%) and potassium sodium content with conventional self-cleaning glaze, easy clean glaze or clear frit (generally exist
More than 3%) different, main purpose is the initial melting temperature in order to reduce overglaze glaze, so as to be conducive in cover coat bottom
Middle layer is formed between ground-coat enamel layer surface, achievees the effect that form three-dimensional sense snowflake line.And 15% is selected to contain as calcium oxide
The upper limit of amount is because if calcium oxide content is excessively high, and the fusing point that begins is too low, the easy burning of cover coat；13% is selected as calcium oxide
The lower limit of content is because if calcium oxide content is too low, and the fusing point that begins is excessively high, and the snowflake line of formation is unintelligible.
3rd, the overglaze glaze composition selection of the low sodium of the low potassium of high calcium can improve overglaze hardness, reduce roughness.Meanwhile
Strontium oxide strontia is added in overglaze glaze, is conducive to improve the surface gloss of glaze paint.And contain silver oxide in overglaze glaze, favorably
In antibacterial.
This is because calcium oxide content and relatively low potassium oxide, sodium oxide content higher in overglaze glaze can also promote
Cover coat forms more calcium and magnesium glass phases, is formed simultaneously less simple glass phase, since calcium and magnesium glass is mutually hard high compared with potassium sodium
Glass is mutually high, therefore makes cover coat more resistant more resistant to corrosion.
Due to the high magnesium of high calcium, high temperature viscometrics are low at high operating temperatures and surface tension is high for overglaze, the overglaze glaze of the embodiment
Material is molten up to 9-11cm, and the molten length of common overglaze glaze only has 7-8cm, and indirect reaction high temperature viscometrics are low, and the reality simultaneously
It applies overglaze frit surface tension in example and reaches 381dyn/cm2, and the surface tension of common overglaze glaze generally only has 374dyn/
cm2.Since the high temperature viscometrics of the overglaze are low, so that the glass that surface is formed mutually melts, effect is more preferable, and glaze paint is more flat, glaze paint
Surface roughness it is lower, be less susceptible to pickup, and since the surface tension of the overglaze is high, what is formed in pyroprocess is micro-
Pore is few, and the soil pick-up of glaze paint is caused to count and is reduced.
4th, the thickness of cover coat can determine size and the gap of snowflake line, in order to avoid snowflake line it is excessive and without apparent
Gap or snowflake line are too small, should be by cover coat thickness control in 0.1mm-0.15mm.If it will be seen that cover coat
Thickness is less than 0.1mm, then can cause in sintering process, cover coat is fully absorbed melting by ground glaze layer, can not form middle layer
There is relief snowflake line under transparent cover coat；And if cover coat is higher than 0.15mm, cover coat can be caused
Ground glaze layer is fully absorbed into melting, can not also form middle layer and there is relief snowflake line under transparent cover coat.
5th, by using frit, since sial content is high in frit, sodium content is few, therefore the beginning fusing point of frit is higher, makes
It is finer and close to obtain (- Si-O-) network structure, improves the hardness of overglaze.
6th, in overglaze glaze preparation method for material, ball milling go out defibrination material granularity below 10 μm accounting control 75% with
On, increase the specific surface area of overglaze glaze so that in sintering process, overglaze glaze absorbs the ability enhancing of heat, can
Reduce the initial melting temperature of overglaze glaze.
