The columnar glass is prepared by mixing raw materials, melting, molding by a mold and cooling, the diameter of the columnar glass is 1-3mm, the length of the columnar glass is matched with the thickness of a blank, and the length of the columnar glass is 2-6mm, and the columnar glass raw material contains high proportion of quartz, so that the columnar glass has a very high melting point after molding, therefore, the columnar glass only slightly melts in the subsequent ceramic sintering process, the integral form of the columnar glass can be maintained, and the columnar glass penetrates through the inside and outside of the blank, so that the part where the columnar glass is located has light transmission and flashing effects.
The stone sense glazed ceramic and the preparation process thereof comprise the following steps:
Step a, preparing stone sense particles;
Step b, mixing paper pulp with other raw materials to prepare paper pulp clay;
Step c, mixing stone sense particles and pulp clay together to prepare a blank;
step d, forming a blank body, and carrying out surface treatment and drying on the blank body;
step e, glazing the blank;
And d, sintering in a kiln.
The preparation process of the stone sense particles comprises the following steps:
Adding water into the container, and uniformly mixing until the mixture is milky;
Adding the milky pigment into the mixture of the kaolin, the quartz and the potassium feldspar, and carrying out vacuum mixing and stirring to obtain color mud; when stone-like particle raw materials are prepared, if pigment is directly added into kaolin for color mixing, uneven color is easily caused; in the invention, the pigment is firstly prepared into emulsion, then mixed with the kaolin, and the pigment is uniformly mixed by vacuum stirring, so that the burnt stone particles are uniformly colored, and the white of the kaolin is used as a primary color for color mixing, so that the color mixing is easy to control.
Beating the color mud into tetragonal bodies, and cutting into mud slices by using a secant;
airing and drying the mud slices;
The dried mud slices are put into a kiln for biscuit firing, wherein the biscuit firing temperature is 900 ℃; after the biscuit firing, organic matters in the mud sheet are decomposed and water volatilizes, and the mud sheet forms certain strength but is not completely sintered.
Crushing the mud slices, sieving to obtain stone granules.
If clay scraps which are not dyed and burned are directly added into the coloring oxide, the clay scraps are melted and softened in the biscuit firing process, the color of the clay scraps is mixed with the blank, and the clay scraps cannot form a granular texture similar to stone; for example, only a layer of glaze or decorative soil is added on the surface of the blank, and lines are engraved on the surface of the blank, so that the stone imitation texture is engraved, the process is complicated, the time consumption is very long, the three-dimensional effect is poor, and the stone imitation effect is poor; therefore, the stone-like particles with color are required to be pre-fired, the stone-like particles are mixed with the blank and then fired, the state of the stone-like particles is stable in the firing process, and the surface of the blank body after firing presents the texture of the stone particles.
In the step d, the molded blank specifically comprises the following steps: after a blank body is formed by pug, baking to be semi-dry, carving a hollowed-out area on the blank body by using a carving knife, drawing a discharging area corresponding to the hollowed-out area on non-woven fabric by using a pen, gluing and adhering the bottom of columnar glass to the non-woven fabric, arranging the columnar glass in the discharging area of the non-woven fabric at intervals, attaching the non-woven fabric to the outer wall of the blank body, enabling the columnar glass to pass through the hollowed-out area of the blank body, filling pulp clay from the inner side of the blank body to the hollowed-out area, filling the pulp clay in a gap between the columnar glass and the blank body, enabling the columnar glass to be embedded into the blank body, tearing the non-woven fabric after the pulp clay is dried, and forming a light-transmitting area on the blank body. By arranging the columnar glass on the non-woven fabric in advance, transferring the arranged columnar glass into the hollowed-out area of the blank body, filling gaps among the columnar glass with pulp clay, and arranging the columnar glass in the hollowed-out area at intervals.
In the step d, after the green body is dried, placing the green body in a container, filling wet sponge blocks between the inner wall of the container and the outer wall of the green body and inside the green body, taking out the green body after placing for 2-3 hours, soaking the outer wall of the green body, brushing the outer wall of the green body by using a brush, then wiping the surface of the green body by using a non-woven fabric, so that the texture of stone particles is exposed on the surface of the green body, soaking, brushing and cleaning the inner wall and the outer wall of a light-transmitting area of the green body, exposing the end parts of columnar glass in the light-transmitting area, and finally drying the green body. Through the special treatment to the body surface for the stone sense granule and the column glass of body outer wall show out from paper pulp clay, show imitative stone feel's texture after the sintering, and the fretwork area then reveals glass granule's texture, and because column glass link up the body inside and outside, therefore fretwork area has the printing opacity effect.
The foregoing is merely a few specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the concept should be construed as infringement of the protection scope of the present invention.
