preparation example 1
[0122] Lead-free ice crystals (average particle size of 0.2-1.0 mm) were melted at a melting point temperature in the range of 620-630°C, that is, a temperature in the furnace of 685-710°C was used. On flat glass having a thickness of about 2 mm, a well-known adhesive is applied to reveal a pattern, and ice crystals are sprayed on it. Then, the flat glass is placed in a drying oven to dry the adhesive completely.
[0123] Thereafter, the flat glass was inserted into an electric radiation furnace with a size of 2.1 m×4.5 m, and thermally cured in a horizontal tempering furnace with a heating temperature of 705° C. for 80 to 90 seconds. Then, the solidified flat glass is quickly transferred to a cooling device of a horizontal tempering furnace, where the flat glass is quenched with cold air having an air pressure of about 18,000˜22,000 Pq for about 30 seconds. Then, cool down for about 50 seconds to 60 seconds. Here, the pressure unit 'Pq' is a standard gas measurement, which ...

[0126] Lead-free ice crystals (average particle size of 0.2-1.0 mm) were melted at a melting point temperature in the range of 620-630°C, that is, a temperature in the furnace of 685-710°C was used. On flat glass having a thickness of about 3 mm, a well-known adhesive is applied to reveal a pattern, and ice crystals are sprayed on it.
[0127] Thereafter, the flat glass was inserted into an electric radiation furnace with a size of 2.1 m×4.5 m, and thermally cured in a horizontal tempering furnace with a heating temperature of 700° C. for 140 seconds. Then, the solidified flat glass is rapidly transferred to a cooling device of a horizontal tempering furnace, where the flat glass is quenched for about 40 seconds by air blowing with cold air having an air pressure of about 10,000˜15,000 Pq. Then, cooling is performed for about 80 to 100 seconds.
[0128] In the above preparation experiments, the melting of ice crystals attached to the flat glass has a melting peak point temper...

[0130] Lead-free ice crystals (average particle size of 0.2-1.0 mm) were melted at a melting point temperature in the range of 620-630°C, that is, a temperature in the furnace of 685-710°C was used. On flat glass having a thickness of about 4 mm, a well-known adhesive is applied to reveal a pattern, and ice crystals are sprayed on it.
[0131] Thereafter, the flat glass was inserted into an electric radiation furnace with a size of 2.1 m×4.5 m, and thermally cured in a horizontal tempering furnace with a heating temperature of 700° C. for 180 seconds. Then, the solidified flat glass is quickly transferred to a cooling device of a horizontal tempering furnace, where the flat glass is quenched for about 50 seconds by air blowing with cold air having an air pressure of about 4000˜6000 Pq. Then, perform cooling for about 100-120 seconds.
[0132] In the above preparation experiments, the melting of ice crystals attached to the flat glass has a melting peak point temperature, and ...
