Several items made from pottery are available in the consumer market today. Each item offers its distinctive characteristics and features to the users.
Earthenware and stoneware are two popular types of pottery-made bodies available to the general public. While they may seem similar, there are considerable differences between earthenware and stoneware.
The durability, practical applications, and costs of earthenware and stoneware differ immensely.
Key Takeaways
- Earthenware is a porous ceramic material fired at a lower temperature than stoneware, resulting in a softer and more fragile product.
- Stoneware is a non-porous ceramic material fired at higher temperatures, making it stronger and more durable than earthenware.
- Earthenware is more susceptible to chipping and cracking, while stoneware is more resistant to these issues due to its strength.
Earthenware vs Stoneware
Earthenware is made from clay that is fired at a relatively low temperature. It is commonly used for making dishes, vases, and other decorative items. Stoneware is fired at a higher temperature and has a dense and durable texture. It is used for making, cooking and baking dishes.
Earthenware is a form of pottery that is porous and coarser than its counterparts. Earthenware is glazed for practical and decorative reasons.
Different options of earthenware are available to the general public. Terracotta is one of the most well-known types of earthenware.
Earthenware continues to be one of the most popularly used storing and decorating mediums in the 21st century.
Stoneware is a form of pottery fired at extremely high temperatures. The name stoneware originates from the stone-like appearance of the body and its dense stone-like quality.
Stoneware is glazed to give it a matte or a more glossy touch. Stoneware came into existence only after earthenware and before porcelain.
Items made from stoneware can be used in microwaves, freezers, and dishwashers.

What is Earthenware?
Earthenware refers to non-vitreous pottery that may be glazed or unglazed. The normal firing temperature of earthenware is below 1200 degree celsius.
Terracotta is a prominent example of basic earthenware that absorbs water. A coating of ceramic glaze is popularly used to make earthenware impervious to liquids.
This coating is commonly used in almost every modern domestic earthenware. There are several characteristics specific to earthenware. They display higher plasticity than most whitewares.
Consequently, it is easier to shape earthenware bodies by using a roller head, RAM press, or potter’s wheel. It is important to glaze earthenware primarily because it has a water porosity of 5-8 %.
The earthenware bodies display a lower mechanical strength. The constituents of earthenware are kaolin, ball clay, quartz, and feldspar.
Some popular types of earthenware are terracotta, redware, victoria majolica, lusterware, raku, ironstone China, and yellowware.
Out of all the types, dark colored terracotta earthenware are most widely used for tiles, flower pots, and decorative ware.
While the rural population in many countries relies on earthen bodies for storing and cooking functions, it has also become popularly used in urban areas.
Clay pots and tin-glazed earthenware are some other viable choices for household usage. While the formal is used to filter water, the latter is primarily used for decorative purposes. Thus, earthenware serves several distinct purposes.
What is Stoneware?
Stoneware is a wide term used to cover pottery materials that are fired at very high temperatures.
Technically, stoneware refers to either a vitreous or semi-vitreous ceramic that uses non-refractory fire clay or stoneware clay. The most well-known quality of stoneware is that it is non-porous i.e. it does not soak up liquids.
Stoneware may or may not be glazed. Around the world, stoneware came into existence only after earthenware and before porcelain. The name stoneware originates from the stone-like appearance and quality of stoneware.
The durability of stoneware is rather impressive. The most common application of stoneware has been for high quality as well as utilitarian wares.
The traditional Asian terminology does not recognise stoneware as a category. Additionally, most of the Asian stoneware is counted as porcelain.
The prominent category of stoneware in industrial settings include traditional stoneware, fine stoneware, chemical stoneware, thermal shock resistant stoneware, and electrical stoneware.
Although stoneware is dense, it is more opaque as compared to porcelain. In most cases, stoneware is glazed. Methods used for making stoneware include moulding, slipcasting, and wheel throwing.
The colour of stoneware is grey or brownish because of the presence of impurities in the clay used for its manufacturing. This dirt look of stoneware stems from the presence of carbon or iron.
The plasticity of stoneware is subject to variation. Stoneware bodies can be fired once or twice during the production process. Thus, stoneware serves as a well known form of pottery today.
Main Differences Between Earthenware and Stoneware
- Earthenware is less durable than stoneware primarily because it is fired at lower temperatures than stoneware.
- Earthenware is can be used occasionally whereas stoneware has the potential to survive a life that includes the indignity of a dishwasher.
- While earthenware is porous, stoneware is non-porous.
- Earthenware is more prone to chipping. On the other hand, stoneware is strong and hard.
- A common application of earthenware is in building bricks, tiles, and dinnerware. In contrast, stoneware is commonly used to make items in freezers and microwaves.
