For the preparation of ceramic products, in particular for making a drinkware, we are
guided by a special recipe, the recipe for making the so-called ceramic mass. Which is
a mixture of raw materials, which is the basis of the ceramic body. In our case, we first
weigh the crushed raw materials - clay and silt, then put them in a special kneading machine,
add liquid
glass as an additive, water and start grinding, which lasts for 7-10
hours. After mixing, we will get a schlicker.
We transfer the schlicker to storage rooms and pour it into molds of different shapes
and sizes, through a specific technique, when the clay takes shape, the rest of the
schlicker is poured back,
we try to harden it to the required condition, and then we open
the tightly bound molds and start removing the already finished product according to the
sequence.
Before being sorted for drying, the heads are worked to ensure the best
possible heads for the plug.
It takes a few hours to dry the product, after which it begins to completely remove
excess particles, straighten the seam area, the head and the base. Drying also helps
prevent deformation and cracking. Due to defects detected during drying, the product is
returned to the kneading machine for processing.
The next stage is firing. The products are placed in the oven and baking begins, which
may require different modes, depending on the condition of the products. Wine vessels
are fired at 1160 degrees, firing lasts for about 5-8 hours.
Then the oven cools down. It is desirable to cool down by itself, without haste.
After complete cooling, we check the unpacked products by applying pressure on the
compressor, so that the damaged ones can be selected and postponed.
The next stage is its coloring. This is the previous step before painting. This is
necessary because most of the models are relief. As a result of coloring, we get a
contrast and a special effect.
The last and no less important stage is its painting. For which we use different paints.
As a result of painting, the product should be finished, get a final appearance, and
highlight the individuality of the product. Varnish is applied before packaging so that the color does not
change during the
bottling of the wine.
It is a rather time-consuming process, requiring the exact observance of technology in
order to obtain a full-fledged product.
