Abstract

The present invention provides a manufacturing method of a decorative artistic pottery ware. The decorative artistic pottery ware is manufactured from pottery mud which has the components of 70 to 80% of ordinary clay, 15 to 25% of river sand and 3 to 7% of water through the steps of mud material processing, forming by using a mold, firing, coloring biscuits, coating water-proof adhesive, etc. The present invention has natural, native, coarse and primitive effects, fits for the moderns' aesthetic mentality of returning to nature, has the advantages of energy saving, easy obtainment of raw materials, low cost and is favorable to protect environments.

Description

A method for manufacturing decorative art pottery

technical field

The invention relates to a method for manufacturing ceramic products, in particular to a method for manufacturing decorative art pottery.

Background technique

At present, there are many varieties of display art pottery on the market. But the surface decoration of traditional furnishing art pottery mainly adopts artificial painted patterns or decals. Artificial color painting patterns are usually made of ceramic pigments or paints. Although they can have a good decorative effect, ceramic pigments generally contain high lead and cadmium, and paint solvents are toxic, which are difficult to meet the requirements of safety, hygiene and environmental protection; and Decorating with decals needs to add a baking process, which increases energy consumption, and the pattern of the product is not natural and realistic enough. In addition, the firing temperature of traditional decorative art pottery is high (above 1050°C), which consumes a lot of energy and the cost of raw materials is also high.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art and provide a manufacturing method of display art pottery, which can make the product have a natural, simple, rough and unrestrained effect, cater to the modern people's aesthetic psychology of returning to simplicity, and save money at the same time. Energy, lower cost and conducive to environmental protection.

The present invention is achieved like this:

A method of manufacturing a ceramic product, the method comprising the steps in the following order:

1. Clay processing and mold making. The formula of the mud material is: 70-80% of ordinary clay, 15-25% of river sand, and 3-7% of water. The diameter of the grain is not more than 0.2mm. The mold is made of gypsum and designed according to the product shape.

2. Impression molding. Put the clay into the plaster mold, and press the blank by hand to form a natural surface texture during the molding process of the ceramic blank.

3. The pottery blank is sintered in a ceramic kiln. The sintering temperature is controlled between 880-920°C for 7.5-8.5 hours.

4. Carry out surface decoration (coloring) to the blank. Water-based paint is directly applied to the surface of the green body, and various decorative techniques such as rubbing, wiping, and patting are used to match the surface texture of the green body to form a natural, simple, rough and unrestrained artistic effect.

5. Apply waterproof glue evenly on the surface of the pottery.

The water-based paint is cement paint for ceramics or latex paint for construction. The waterproof glue is a styrene synthetic agent.

The pottery of the present invention is suitable for use in public places, private rooms or garden decorations, and is especially suitable for economically developed countries and regions such as Europe and America.

The beneficial effects of the present invention are:

1. Saving energy and resources: The product is only fired once at a low temperature of 880-920°C. After decoration, there is no need for secondary firing, low energy consumption, and the use of ordinary clay and river sand does not compete with other ceramic products for resources.

2. Low material cost: The raw materials used, such as clay, river sand, cement paint for ceramics and styrene synthetic agent, are relatively cheap and easy to obtain.

3. The decoration process on the surface of the product is harmless to the human body and will not pollute the environment, so it is more suitable for mass production.

4. The product has a natural, simple, rough and unrestrained artistic effect.

Detailed ways

Below by example, the present invention can be further understood.

Example 1 Manufacturing method of hand-pressed stoneware flowerpot

(1) Clay processing and mold making. According to the proportion (percentage by weight) of 75% of ordinary clay, 20% of river sand and 5% of water, the clay with plasticity is obtained through compounding and stirring evenly, and the diameter of the river sand grains is not more than 0.2mm. Using gypsum as a raw material to make a mold for printing flower pots, the mold can make the product have a simple, natural, and rough classical shape, plus smooth and beautiful clues and patterns to create a beautiful effect.

(2) Impression molding. Put the clay into the plaster mold, and press the blank by hand to form a natural surface texture during the molding process of the ceramic blank. During the compaction process, the thickness of the blank wall is appropriately increased to enhance the strength of the ceramic blank. Trimming is carried out after compaction is completed.

(3) The pottery blank is sintered in a ceramic kiln. The sintering temperature is 900°C, and the sintering time is 8 hours.

(4) Surface decoration (coloring) is carried out on the green body. Select the desired color (such as yellow, green, pink, etc.) of special cement paint for ceramics and apply it directly on the surface of the green body, and then use various decorative techniques such as rubbing, wiping, patting, etc., to match the surface texture of the green body to form a natural finish. , Simple, rough and unrestrained artistic style. After decoration (coloring) and drying, the color has been deeply absorbed on the surface of the green body.

(5) Apply a layer of styrene compound evenly on the surface of the pottery to prevent moisture and water, and then make a hand-pressed rough pottery flower pot.

Example 2 Manufacturing method of hand-pressed glazed pottery flowerpot

Step (1) is the same as Example 1.

Step (2) Die forming is the same as Example 1. After the die is formed, enamel is applied on a part of the surface of the pottery according to the product design pattern requirements.

Step (3) is the same as example 1.

Step (4) When carrying out surface decoration (coloring) on the biscuit, the glazed part is no longer colored, and only the unglazed part is coated with special cement paint for ceramics.

Step (5) is the same as Example 1, namely to make a hand-pressed glazed pottery flower pot.

Example 3 Hand-pressed stoneware animal sculpture

Except that the gypsum mold made in step (1) is shaped as an animal, other steps are the same as Example 1, so that hand-pressed rough pottery animal sculptures are made.

Claims (3)

1. the manufacture method of a furnishing art pottery is characterized in that, it comprises the following steps:
