(C) using crystallization thermal gradient furnace is surveyed, measure the various glass materials for needing and measuring~~recrystallization temperature reaches the standard grade [peak] and offline [minimum point].

(D) a kind of glass melting furnace is used, reach the standard grade [i.e. the peak] in devitrification of glass humidity province starts, and under conditions of progressively lowering the temperature, the crystallization speed to different glass carries out method of testing：(it is not to receive first have correlation technique to enlighten, even the test purpose feature and test equipment and method of testing of the new material property of devitrification of glass speed, it is also the defect caused according to the crystallization of the exclusive technical vulnerability formation in big production of type products of the present invention, and creating and pioneering).

In the description of the present invention, the size of the minute numerical value of all crystallization speed, and so as to judge the speed of crystallization speed, all with using the same glass melting furnace partly indicated under this, and based on the data that are drawn of method of testing of the crystallization speed to different glass partly indicated under this：

A. the glass melting furnace for selecting is characterized in：

1. glass melting furnace has, to the display instrument of the accurate thermometric of the temperature of furnace interior, for observing and recording the change of temperature.

2. the overall heat-insulating property of the glass melting furnace of selection will get well, and being provided with can control in-furnace temperature, at the uniform velocity the heat sink of gradient；The temperature in stove can be made, at least kept for 150 minutes or more time, just complete the progressively temperature-fall period of 1300~850 DEG C of temperature in stove；Complete the progressively temperature-fall period for being the enough time, just completing 1300~850 DEG C of temperature in stove that temperature of the glass metal in stove at least keeps 150 minutes or more.(because the scope of reaching the standard grade of the devitrification of glass humidity province of product of the present invention, all within 1300~850 DEG C, the scope of reaching the standard grade of the devitrification of glass humidity province of such as certain product is the overwhelming majority：1230~920 DEG C)

B. test purpose：

Because product of the present invention has the characteristics of reaching the standard grade [peak] higher than forming temperature of recrystallization temperature, so in order to study in big production if selectivity is using with the slow glass of crystallization speed, it is advantageous for the especially cooling work portion before being molded in big production, in the glass metal temperature reduction technology stage, reduce the risk of glass metal crystallization；Especially some heating control apparatus can be increased at the liquidus edge in cooling work portion and turning and these places for being easy to crystallization of bottom, and add to ask temperature control is reached the standard grade 50~80 DEG C to higher than recrystallization temperature；

But the state of reality is, at the turning and bottom in cooling work portion, because glass metal has the slower region of some flowings, so some products, when in the slower region of some flowings, temperature of glass liquid declines comparatively fast, is begun to decline from recrystallization temperature summit, only in 10~31 minutes, the glass metal of this kind of product just produces local crystallization.This will make this kind of product, in big production, after formative stage is entered, it is easy to the underproof risk of product of glassware part devitrification occur.

So should be in big production, selectivity uses the present invention with the slow glass product of crystallization speed, because it has the slow property of crystallization speed：In 45~70 minutes or 60~90 minutes or in 60~150 minutes, crystallization is not produced under conditions of temperature of glass liquid begins to decline from recrystallization temperature summit.Present invention discover that this glass material the slow-footed property of glass metal crystallization, can advantageously account at the turning and bottom in cooling work portion, when the problem of local devitrification in some slower regions of flowing；Because glass metal crystallization speed is slow, so in the slower region of some flowings, the risk of the substandard product for being easy to make the glassware shaping stage local crystallization devitrification occur can be overcome.

C. the method for testing of the crystallization speed of different glass：

The first step, first using crystallization thermal gradient furnace is surveyed, measure the various glass materials for needing and measuring~~recrystallization temperature reaches the standard grade [peak] and offline [minimum point].

Second step：

1. frit is put into dissolving dry pot；

2. in placing into a kind of glass melting furnace；

3. after dissolving, glass melting furnace is progressively lowered the temperature；

4. the reaching the standard grade [peak] of the recrystallization temperature according to this measured glass (as 1230~~920 DEG C), observe the time period of the time for progressively cooling to (such as 1230 DEG C) measure needed for of the accurate thermometric display instrument of the temperature of furnace interior；

5. dry pot is dissolved as taken out after 20 minutes, glass metal can quickly be cooled to glass, observe whether it has crystallization；So as to draw this measured glass, from the property of the crystallization speed progressively lowered the temperature 20 minutes of the reaching the standard grade of recrystallization temperature [peak]；Or dry pot is dissolved in taking-up after 45 minutes；Or dry pot is dissolved in taking-up after 60 minutes；Or dry pot is dissolved in taking-up after 90 minutes；Or dry pot is dissolved in taking-up after 120 minutes；Or dry pot is dissolved in taking-up after 150 minutes；This measured glass is just obtained, from the property of the crystallization speed progressively lowered the temperature 20,45,60,90,120,150 minutes of the reaching the standard grade of recrystallization temperature [peak].

(E) about the method for tested viscosity temperature, high-temperature viscosimeter is rotated using U.S. THETA.

(F) relevant test rupture strength, by sample being cut into the small bar of 50mm × 50mm × 5mm, using rupture strength instrument, is determined by standard GB/T3810,4~2006.
