Moving through...

Hi everybody,

In the upcoming weeks we will explain you words related to “Vietnamese potteries”. Last week, we explained how the Vietnamese developed their pottery skills and how it is shared and spread through the whole country. So, Vietnamese potteries stands for pottery designed and/or produced in Vietnam.
We have picked some words and this week's words are: Vietnam, Ceramic, Kaolinite, Earthenware and Stoneware.

Vietnam is a country in South- East Asia. The country is bordered by China in the north, Laos to the northwest, Cambodia to the southwest and the South China Sea to the east. (http://en.wikipedia.org/wiki/Vietnam)

Ceramic comes from the Greek word κέραμος (keramos) which is “potter’s clay, tile, pottery”. The solid is prepared by the action of heat and subsequent cooling. The earliest ceramics made by humans were pottery objects made from clay. Later glazing became part of the process to create a smooth colored surface. However, there are many different kinds of ceramics, our focus will be mainly on whiteware ceramics, earthenware and stoneware.

Kaolinite, the traditional ceramic raw material comes from clay minerals such as kaolinite (kaolin).

Terracotta (Earthenware) 
Earthenware, a generic composition of earthenware is ball clay, kaolin, quartz and feldspar. Earthenware that has been transported by moving water moves a long distance before it is settled in a river bed. While the earthenware is moving, it picks up minerals and materials. Earthenware is low- fire clay and is often white or gray, unless it is glazed. Also earthenware is commonly used to create Terracotta pots, planters etc.

Stoneware, a generic composition of stoneware is plastic fire clays, ball clays, quartz, feldspar and chamotte. Stoneware is hard and durable clay. The natural colors vary from light grey or tan to dark grey or chocolate brown, unless it is glazed.

Ironstone (Stoneware) 
That was it for today hope you all have enjoyed it and see you next week!
