What Is Better Stoneware Or Porcelain?
Introducing Stoneware and Porcelain
Stoneware and porcelain are both types of ceramics made from clay that is heated to high temperatures in a kiln. While they share some similarities, they have distinct differences in their properties and uses.
Stoneware is a dense, hard, non-porous ceramic that can be glazed or unglazed. It originated in China over 2,000 years ago, and became popular in Europe in the Medieval times. Stoneware is valued for its durability and thermal shock resistance. It’s commonly used to make cookware, bakeware, tableware, art pottery, and building materials like architectural tiles.
Porcelain originated in China over 1,000 years ago, and was initially only available to the wealthy. It is made from kaolin clay and is fired at very high temperatures up to 1400°C to vitrify and become non-porous. Porcelain is highly prized for its bright white color, durability, and delicacy. It is translucent and resonates with a pure tone when struck. Porcelain is used to create dishware, art objects, figurines, sanitaryware, electrical insulators, and dental prosthetics.
While stoneware has an earthier, matte look from the clay minerals, porcelain has a bright, white, refined appearance and delicate translucency resembling fine bone china. Both provide strength and durability, but porcelain is more brittle and prone to chipping compared to stoneware.

Appearance
There are some notable differences in the appearance of stoneware and porcelain in terms of color, glaze, and texture. Stoneware tends to have earthier, matte colors and finishes. The clay has a coarser grain, giving stoneware a more rustic, textured look. Glazes on stoneware also tend to be thicker and less glass-like compared to porcelain. In contrast, porcelain has a finer, smoother texture and tends to be bright white or light-colored due to the purity of the clay. Porcelain glazes are thinner and have a glassy, shiny finish. According to Made In Cookware, stoneware is best known for its muted, natural tones while porcelain “tends to predominate in colors like bright white, bone, light blue, light green and soft pink.” The different textures and glazes make stoneware better suited for more casual, everyday tableware while porcelain has an elegant, sophisticated look.
Strength and Durability
When it comes to how strong and durable stoneware and porcelain are, there are some key differences. Porcelain tends to be more resistant to chips and cracks than stoneware according to Porcelain Dinnerware vs. Stoneware: Which One Is Better?. Porcelain is fired at higher temperatures, making it denser and less porous than stoneware. This density makes porcelain more resistant to chipping or breaking from impacts or drops. Porcelain also has superior thermal shock resistance compared to stoneware. Thermal shock occurs when there is a rapid temperature change and can lead to cracks or breaks. The high firing temperatures make porcelain very durable against temperature fluctuations.
However, stoneware does have some advantages when it comes to strength according to Porcelain or stoneware: here are all the differences and advantages. While more prone to chips and cracks, stoneware can better withstand thermal shock stresses. The lower firing temperatures keep stoneware from becoming as brittle, so it is less likely to completely shatter from impacts. Additionally, stoneware glazes tend to be more scratch resistant than porcelain glazes.
Overall, porcelain rates higher in durability and resistance to chipping, cracking, and thermal shock. But stoneware is less likely to fully break apart when damaged. For most household uses, porcelain offers superior strength and longevity.
Porosity
One of the most significant differences between stoneware and porcelain is porosity, or how absorbent the material is. Porcelain has an extremely low porosity and is considered practically non-porous. It has a very dense clay body that does not absorb moisture [1]. In contrast, stoneware is more porous due to the materials added to the clay before firing. While less porous than earthenware, stoneware can absorb some moisture, around 3-5% [2]. The higher porosity makes stoneware more prone to staining from foods and liquids compared to porcelain.
Thermal Properties
Stoneware and porcelain have different thermal properties due to their composition and firing temperatures. Porcelain is fired at a much higher temperature, typically around 1300-1400°C, compared to stoneware which is fired around 1100-1200°C (Stoneware vs. Porcelain: The Major Differences). This higher firing temperature makes porcelain harder, denser, and more resistant to thermal shock.
Porcelain has very low porosity, which gives it superior thermal conductivity compared to stoneware. The dense non-porous nature of porcelain allows it to transfer heat smoothly and evenly. Stoneware, with its slightly more porous body, is not as conductive and prone to uneven heating (Porcelain versus Porcelain Stoneware: So Close, So …).
The high firing temperature also makes porcelain highly resistant to thermal shock. Rapid temperature changes do not crack or damage porcelain like it can with stoneware. As a result, porcelain dishware can go from freezer to oven to table with ease. Stoneware is much more prone to breaking from sudden temperature swings.
In summary, porcelain has superior thermal properties compared to stoneware due to its dense composition and high firing temperature. Porcelain conducts heat smoothly, resists thermal shock, and can withstand extreme temperature fluctuations that would crack stoneware.
Ease of Use
When it comes to ease of use, stoneware and porcelain have some key differences in sculptability, throwing, and glazing.
Stoneware clay is generally easier to sculpt by hand compared to porcelain. Stoneware has more plasticity and flexibility, allowing it to be pushed and pulled into various shapes without cracking or tearing1. Porcelain’s stiff, dense nature makes it more prone to cracking during hand sculpting.
On the wheel, porcelain is known for being difficult to throw and shape due to its lack of plasticity. It does not center well on the wheel and can easily slump or collapse if thrown too thin2. Stoneware has more clay body and is more forgiving during wheel throwing, making it an easier material for beginner potters to learn with.
For glazing, porcelain’s low porosity requires glazes to be applied very thinly to prevent crazing. Stoneware can accept thicker layers of glaze without issue. However, porcelain’s smooth white surface shows off glaze colors more vibrantly. Overall, glazing stoneware tends to be more forgiving and beginner-friendly.
Cost
Porcelain generally costs more than stoneware due to differences in material and production costs. According to MadeInCookware, porcelain utilizes higher quality kaolin clay and requires a more complex production process. Making porcelain involves higher temperatures and more meticulous techniques to create delicate items.
As Nonamehiding explains, stoneware uses lower quality clay and is much easier to shape and fire. This makes it faster and cheaper to produce. Additionally, porcelain is usually crafted into thinner and more detailed pieces. The effort required to make intricate porcelain raises the price significantly compared to sturdy stoneware.
Maintenance
When it comes to cleaning and caring for stoneware and porcelain, there are some differences in the recommended methods. Porcelain is less porous than stoneware, so it does not absorb stains and odors as readily. According to this source, porcelain can be washed in the dishwasher but may become cloudy over time. It’s best to wash by hand using mild detergent. Avoid abrasive cleaners that could scratch the surface. Porcelain is also prone to chipping if dropped or mishandled.
Stoneware is more porous and prone to absorbing stains, so cleaning needs to be more thorough, as mentioned in this article. Letting stains set in makes them harder to remove later. Stoneware can usually be washed in the dishwasher, but handwashing is recommended, especially for decorative pieces. Avoid harsh scrubbing that could damage the finish. Stoneware also needs to be protected from extreme temperature changes to prevent cracking.
With proper care, both stoneware and porcelain can last a very long time. But porcelain generally requires less maintenance to keep it looking pristine.
Environmental Impact
When comparing the environmental impact of stoneware and porcelain, there are a few key factors to consider. Porcelain often has a lower overall impact than natural stoneware.[1] This is because porcelain tile manufacturing has become more energy-efficient and uses fewer raw materials over time. Porcelain production recycles water used in the manufacturing process and reuses waste materials as well.[2]
Porcelain tiles are primarily made of clays, feldspar, and mineral pigments that have minimal environmental impact to source.[3] The raw materials for porcelain come from responsible, ethical sources. Porcelain tiles can also be recycled after use.
In contrast, natural stonewarequarrying can damage habitats, erode soil, and consume energy for extraction and transportation. There are also concerns around unsafe labor practices and child labor in some natural stone quarrying operations.[1]
Ultimately, porcelain tile’s lower resource consumption, energy efficiency, recyclability, and ethically-sourced raw materials give it an environmental advantage over natural stoneware in most cases.
