the main body glaze slip is prepared by the following method: putting 300 parts by weight of glaze stone, 35 parts by weight of iron oxide red, 35 parts by weight of talc, 50 parts by weight of limestone, 200 parts by weight of potash feldspar and 620 parts by weight of water into a ball mill for grinding, and sieving by a 100-mesh sieve to obtain main body glaze slurry;

the mouth edge glaze slip is prepared by the following method: 300 parts by weight of kaolin, 35 parts by weight of talc, 50 parts by weight of limestone, 200 parts by weight of potash feldspar and 580 parts by weight of water are put into a ball mill for grinding, and the ground materials are sieved by a 100-mesh sieve to obtain the lip glaze slurry.

(2) Glazing: applying glaze slurry along the inner and outer walls of the blank body at a position 6mm below the edge of the blank body, and airing, wherein the glazing thickness is 0.2 mm; and then, pouring the body glaze slip into the body, staying for 6s, reversely buckling the body into the body glaze slip, soaking for 3s, not glazing the outer bottom of the body, and drying to obtain the glazed body.

(3) Roasting: placing the glazed green body into an electric kiln for roasting, wherein the roasting comprises the following steps:

heating the furnace temperature from 20 ℃ at normal temperature to 1350 ℃ at the rate of 170 ℃/h, preserving heat for 1h at 1350 ℃, then putting firewood into the electric kiln in the state of preserving heat at 1350 ℃, putting once every 3min for 5 times, putting 400g firewood into each cubic meter of electric kiln space each time, after the firewood is put, cooling the furnace temperature from 1350 ℃ to 1150 ℃ at the rate of 130 ℃/h, powering off the electric kiln, opening the furnace door, naturally cooling the furnace temperature to 1040 ℃, closing the furnace door, putting firewood into the electric kiln, putting once every 5min for 4 times, putting 250g firewood into each cubic meter of electric kiln space each time, after the last time of putting 5min, opening the furnace door, naturally cooling the furnace temperature to 900 ℃, closing the furnace door, opening the furnace door after 1.5h, naturally cooling to 20 ℃ at normal temperature, and obtaining the silvery luster obsidian construction cup.

Evaluation of the effects:

the obsidian made in this example 1 is shown in fig. 1 and fig. 2, it can be seen that the texture of the edge of the obsidian is clear, the mimic is fresh and the texture is magnificent and unique, the glaze below the texture of the edge has glittering and translucent oil drops with silver diaphragm, the glaze of the oil drops is glaring and glaring, and the glaring and glaring are glaring and glaring, and the glaring and glaring looks like operating in universe in the vastly and profound cymonomo survey, and the substrate of the object is hidden, and the glaze of the obsidian is moist, and has no plaque, no pore and good texture, thereby having beautiful art and collection value.

Comparative example 1

The process for preparing the cup of the comparative example 1 is the same as that of the example 1, except that: glazing in step (2):

and (3) pouring the body glaze slip into the body, staying for 6s, reversely buckling the body into the body glaze slip, soaking for 3s, not glazing the outer bottom of the body, and drying to obtain the glazed body.

Evaluation of the effects:

the cup prepared in comparative example 1 had a blurred and dull texture and a poor texture at the rim.

Comparative example 2

The process for preparing the cup of the comparative example 2 is the same as that of the example 1, except that: in the step (2):

the main body glaze slip is prepared by the following method: putting 300 parts by weight of glaze stone, 10 parts by weight of iron oxide red, 20 parts by weight of talc, 20 parts by weight of limestone and 350 parts by weight of water into a ball mill, grinding, and sieving by a 100-mesh sieve to obtain main body glaze slurry.

Evaluation of the effects:

the glaze of the cup prepared in the comparative example 2 has the advantages of no silvery light, dull, fuzzy flaky, rough and speckled oil drops and poor texture.

Comparative example 3

The process for preparing the cup of the comparative example 3 is the same as that of the example 1, except that: roasting in step (3): placing the glazed green body into an electric kiln for roasting, wherein the roasting comprises the following steps:

heating the furnace temperature from 20 ℃ to 1350 ℃ at the normal temperature at the rate of 170 ℃/h, preserving heat for 1h at the temperature of 1350 ℃, then putting the firewood into the electric kiln under the heat preservation state of 1350 ℃, putting the firewood once every 3min for 5 times, putting 400g of firewood into each cubic meter of space of the electric kiln every time, after the firewood is put into the electric kiln, cooling the furnace temperature from 1350 ℃ to 1150 ℃ at the rate of 130 ℃/h, powering off the electric kiln, opening the furnace door, naturally cooling the furnace temperature to 1040 ℃, closing the furnace door, putting the firewood into the electric kiln, putting the firewood once every 5min for 4 times, putting 250g of firewood into each cubic meter of space of the electric kiln every time, opening the furnace door after the last time of putting the firewood for 5min, closing the furnace door when the furnace temperature is naturally cooled to 900 ℃, cooling the furnace door to the normal temperature of 20 ℃, and obtaining the building block.

Evaluation of the effects:

the glaze of the cup prepared in the comparative example 3 has no silvery oil drops, is rough and has dry and scorched feel, and is poor in texture.

Comparative example 4

The process for preparing the cup of the comparative example 4 is the same as that of the example 1, except that: roasting in step (3): placing the glazed green body into an electric kiln for roasting, wherein the roasting comprises the following steps:

heating furnace temperature from 20 ℃ to 1350 ℃ at the rate of 170 ℃/h, preserving heat for 1h at 1350 ℃, then throwing firewood into the electric kiln at the heat preservation state of 1350 ℃, throwing once every 3min for 5 times, throwing 400g firewood into each cubic meter of electric kiln space each time, after the firewood is thrown, cooling the furnace temperature from 1350 ℃ to 1150 ℃ at the rate of 130 ℃/h, powering off the electric kiln, opening a furnace door, and naturally cooling the furnace temperature to 20 ℃ at the normal temperature to obtain the building cup

Evaluation of the effects:

the cup prepared in the comparative example 4 has fuzzy texture at the rim, and has no silvery oil drops, dark glaze, pores and plaques.

While the invention has been described in terms of a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
