Ceramic Sampling Process Explained: A Comprehensive Analysis

In the process of tailoring ceramic products, Ceramic Sampling is an indispensable link in quality assurance and product design implementation. To customers who need bulk procurement or brand customization, samples are not just display items but rather the “blueprint” for future mass production.

As a manufacturer and wholesaler with experience in daily-use ceramics, Jinhua knows just how important samples are and conducts a professional, systematic ceramic sampling process for various types of products, from tableware and baking trays to bathroom sets and candle jars, in a way that allows every product to perfectly reflect the client’s brand concept.

What is Ceramic Sampling? Why is it so crucial?

Simply put, Ceramic Sampling is the sample confirmation stage before the production of Keramik-Sonderanfertigungen.

In this process, the manufacturer will create samples based on the client’s design, color, size, and logo requirements for evaluation. Its importance lies in three aspects:

• Verifying design feasibility: Confirming whether the product’s shape, glaze, and texture meet expectations through samples.
• Guaranteeing Mass Production Quality: Confirmation at the sample stage ensures consistency between the bulk order and the sample, avoiding batch errors.
• A Bridge for Brand Communication: Samples are the most direct medium for communication between clients and the factory, enabling more efficient integration of design and production.

In Jinhua’s production system, ceramic sampling is a standardized process for every project. Whether clients require ceramic tableware, baking trays, candle jars, or bathroom sets, sample testing ensures the final product is presented perfectly.

Jinhua’s Ceramic Sample Process: From Design to Prototype

1. Client Needs Communication

Before starting production, the Jinhua design team will discuss details with clients about product requirements, from the shape and size to usage and color, including even the packaging. For instance, tableware sets put more emphasis on aesthetic harmony, while heat resistance is emphasized for ceramic baking trays.

We provide professional advice through proper glaze selection, printing methods, and options of logo customization, understanding the positioning and market objectives of the client.

2. Design Confirmation and Prototype Planning

After confirming the design scheme, Jinhua will develop a sample plan based on the product type.

The general ceramic sampling cycle is 7–15 days but will vary based on the specifics of the customization. On projects that involve a new mold, such as specially shaped baking trays or scented candle jars, we will initiate a custom mold-making process to ensure accurate form.

3. Shaping and Bisque Firing

The shaping of the clay during the sample making stage is done by pressing or slip casting, after which it undergoes the bisque firing stage.

The purpose of this step is to remove the moisture and stabilize the structure, preparing it for subsequent glazing. The high-precision mold is designed to make each sample consistent in shape and with a smooth surface.

4. Glazing and High-Temperature Firing

Glazing is among the most critical steps that determine the look and feel of a ceramic. Jinhua provides a wide range of glazes, including high-gloss glaze, matt glaze, crackle glaze, and color glaze.

During the ceramic sampling stage, the customer can assess the brightness, gloss, and texture of the glaze by examining the samples.

Next, we will do a high-temperature or low-temperature firing:

• HT firing, around 1300°C, increases the hardness and resistance to heat, which will make them suitable for baking trays and tableware.
• Low-temperature firing at about 800°C–1000°C: This preserves bright colors and minute details of decoration; examples include candle jars and bathroom sets.

5. Printing and Decoration

For Custom Ceramic Products, the brand logo or decorative pattern is key to brand recognition.

Jinhua supports various processes such as screen printing, decals, hand-painting, and hot stamping. The position and size can be flexibly adjusted according to the sample effect, ensuring both brand presentation and aesthetic appeal.

6. Sample Testing and Customer Confirmation

After the sample is completed, Jinhua’s quality control team will test it from multiple aspects, including size, weight, color difference, heat resistance, and gloss.

After the customer confirms the sample, we will retain a standard sample for comparison and control during mass production, ensuring that the batch products are completely consistent with the sample.

Sample Process Characteristics for Different Products

1. Ceramic Dinnerware Samples

Keramisches Essgeschirr samples emphasize gloss, thickness, and stacking stability. We will test scratch resistance, acid and alkali resistance, and surface smoothness to ensure that it remains like new even after long-term use.

2. Baking Dishes Samples

Baking dishes samples must pass a high-temperature heat resistance test to ensure they do not crack or deform in the oven. Oil stain resistance testing of the glaze is a crucial step to ensure easy cleaning and food safety.

3. Bathroom Sets Samples

Bathroom set samples must balance water resistance and aesthetics. Jinhua offers a variety of styles—from minimalist white porcelain to colorful glazes—allowing customers to easily find a design that matches their bathroom style.

4. Candle Jars Samples

Candle jar sample testing focuses on heat resistance, wax leakage prevention, and sealing performance. Customers can determine the color, lid shape, and logo display effect at the sample stage, providing accurate reference for subsequent mass production.
