Porcelain Buying Guide: How to Choose the Best Quality

TL;DR: To choose the best quality porcelain, inspect the piece for a dense, translucent white body and a smooth, glossy glaze that feels cool to the touch. Ensure the manufacturer uses high-temperature kiln firing and guarantees the product is free from pinholes, crazing, or uneven edges.

Understanding Porcelain Grades

Before examining specific items, understand that porcelain is not a monolith. There are generally two main types: bone china and hard-paste porcelain. Bone china contains calcium phosphate derived from animal bones, which gives it exceptional strength and a warm, milky white hue. Hard-paste porcelain is made from kaolin and feldspar, resulting in a whiter, more rigid material. For most tableware needs, high-quality bone china is often preferred for its durability and elegance, while hard-paste is a more affordable alternative that still offers excellent performance if sourced from reputable manufacturers.

Step-by-Step Inspection Process

Start by holding the piece up to a light source. High-quality porcelain should exhibit a degree of translucency. If you can see the shadow of your hand or a distinct outline through the rim of a cup or plate, it is likely a high-grade piece. Opaque, chalky-looking items are usually lower quality or made from a different clay body entirely. Next, run your finger over the glaze. It should feel glassy and smooth, without any roughness or grit. Any imperfections here can harbor bacteria and are difficult to clean over time.

Check the weight and balance. Genuine porcelain is surprisingly light for its size due to the vitrification process that occurs during high-temperature firing. If a piece feels unusually heavy or dense, it may be made from earthenware or stoneware, which are less durable and more porous. Hold the item by the handle or edge and gently shake it. There should be no rattle or clink, indicating that the glaze is securely bonded to the body. A loose glaze can chip or crack under normal use, rendering the piece unusable.

Identifying Flaws and Defects

Look closely for pinholes, which are tiny air bubbles trapped in the glaze. While minor pinholes are common in hand-thrown pieces, they indicate a lower standard of industrial quality. More critically, check for crazing, which appears as a network of fine cracks in the glaze. Crazing occurs when the glaze and the clay body shrink at different rates during cooling. This is a structural weakness that allows liquids to seep into the clay, causing stains and odors that are nearly impossible to remove. Avoid any item with visible chips or uneven rims, as these are signs of poor handling during production or shipping.

Examine the foot of the piece, which is the unglazed bottom part. It should be clean and free of excess clay or drips. A rough foot can scratch table surfaces and make the plate unstable. If the foot is glazed, ensure the glaze does not run too thin, which can lead to wear over time. For sets, check that all pieces match in color and pattern. Inconsistent coloring is a sign of poor quality control and can make your table setting look uneven and amateurish.

Material and Care Considerations

Read the manufacturer’s specifications carefully. Look for keywords like “dishwasher safe,” “microwave safe,” and “oven safe.” High-quality porcelain can withstand the heat and chemical agents found in dishwashers without degrading. If a piece is not dishwasher safe, it requires immediate hand washing to prevent glaze damage. Additionally, consider the source. Buying from established brands or certified artisans often provides better warranties and quality assurance than generic, unlabeled products. Finally, remember that proper care extends the life of your investment. Avoid placing hot pans directly on cold porcelain, as thermal shock can cause cracking. By following these steps, you ensure that your porcelain investment remains beautiful and functional for decades.
