Vietnam Pottery Manufacturing process – Amazing story of traditional pottery from part of world

 

Several factors can be described as a reason for the sophistication and beauty of Vietnamese pottery, giving each of them a unique identity in texture and color.

The first difference in their manufacture, with respect to the type of clay found in Vietnam, eastern Indochina peninsula with a chemical composition very rich in "Mica", these vessels have a greater resistance than those made from red clay, rich iron, which is normally found in other parts of the world.

At the Vietnam manufacturing process, the clay is added to the "grog" a refractory which increases the resistance of the ceramic during baking, allowing it to reach a temperature of 1300 ° for 3 days while the red ceramic does not exceed 1,100 ° before the casting.

Also in the manufacturing process, the vases are made in molds Vietnamese and not on lathes, this causes them to be applied thicker layers of clay inside the mold, making these pots nearly twice the thickness of the manufactured elsewhere. The healing process of the ceramic occurs between 60 and 90 days in the open or in greenhouses, taking advantage of the hot and dry climate of southern Vietnam.

Also the painting process gives a unique feature Vietnamese vessels. Its paint is derived from the use of the base resin enamels, glazes and paints and not commonly used in ceramic products.

When this resin by mixing glass powder or silica (sand), and other chemical pigments such as cadmium, cobalt, zinc, lead, chromium, among others, and elava them to high temperatures, one can obtain a unique color for each pot , and the spots gradient and different shades in the same pots are determined by factors such as the variation in internal temperature of the wood ovens, causing greater or lesser chemical reaction of the pigments, the use of agents on the basis of excitation or mouths the vessels, and even intentional use of two or more pigments in order to color tones with one or more same pots.

The clay pots manufactured in other countries use electric or gas ovens in most cases. This combined with the humidity pottery in these processes, resulting in lower strength of their pots. Another noticeable difference is with respect to painting, enamel used in other countries, drawn up in bathrooms or hand, produces a final uniform in color and surface with low viscosity and density in the enamel, different from the result obtained from the resinous paint Pots of Vietnamese.

With all this, we can ensure the exposure of Vietnamese pots at any temperature and climate condition, without altering its color or resistance, making them very popular for decorating both indoors and outdoors.
