Xinxiang Ceramic Mug Manufacturer, A double-layer ceramic mug consists of two layers of ceramic material that form an insulating barrier between the inner and outer walls. This design helps to keep coffee hot or cold for long periods of time while preventing the exterior from becoming too hot to touch. Often used for serving coffee, tea and other beverages, double wall mugs are both aesthetically pleasing and functional.

1. Advantages of double wall ceramic mugs

Insulation: Keeps drinks at the desired temperature for a long time.
Comfort: Reduces the risk of burning your hands on hot drinks.
Prevents condensation: Helps prevent moisture from forming on the outside when serving cold drinks.
Aesthetics: Often have a unique design and a modern look.
When choosing a double walled ceramic mug, consider factors such as size, design, microwave and dishwasher safe, as double wall ceramic mugs may vary from brand to brand and model to model.

2. Raw materials of double-layered ceramic mugs

The raw materials of double-layer ceramic mugs mainly include: kaolin, quartz sand, feldspar and limestone.
Kaolin: kaolin has a high degree of whiteness, high quality features, its composition is relatively stable, not easy to deteriorate, to ensure the stability of the material and quality of double-layer ceramic mug.
Quartz sand: quartz sand has the characteristics of high hardness and light colour, which can improve the hardness and abrasion resistance of double-layer ceramic mugs after firing, making them more durable.
Feldspar: Feldspar plays a role in regulating the chemical composition and firing temperature during the production of double-layer ceramic mugs, which helps to form the unique physical and chemical properties of double-layer ceramic mugs.
Limestone: Limestone is also used to regulate the chemical composition and firing temperature of double-layer ceramic mugs, and has a significant impact on the firing process and final performance of double-layer ceramic mugs.
In the proportion of raw materials, generally adjusted according to the specific production needs and process requirements, but the common ratio is roughly 40-50% of kaolin, quartz sand accounted for 25-30%, feldspar accounted for 20-25%, limestone accounted for 5-10%.

3.The production process of double-layer ceramic mugs

1).  Raw material preparation: mix kaolin, quartz sand, feldspar and limestone according to a certain proportion of raw materials, and after grinding, sieving and other processes to ensure the fineness and uniformity of raw materials.
2).  Mould: According to the customer's size requirements for double-layer ceramic mugs, the mould is made. The mould can be used only after the grouting test.
3).  Grouting: The double-layer ceramic mugs are made by grouting process. Grouting process is the use of gypsum mould water absorption, the mud with fluidity into the gypsum mould, so that the mud dispersed adhering to the model, the formation and the model of the same shape of the billet layer of clay, and with the extension of time and gradually thickening, when it reaches a certain thickness, after drying and shrinkage and detachment of the mould wall, and then take out of the mould, the billet system is completed.
4).  Moulding: the mixed raw materials through the grouting moulding for the double-layer ceramic mug blank. The moulding process needs to control the thickness and shape of the blank to ensure the quality of the final product.
5).  Drying: The moulded blanks are placed in the drying room for drying treatment to remove the moisture and organic substances in the blanks. Temperature and humidity need to be controlled during the drying process to avoid cracking or deformation of the blanks.
6).  Glaze: Apply a thin layer of glaze on the dried blank. The choice of glaze needs to take into account the use of double ceramic mugs and decorative effect. Glazed blanks need to be dried for subsequent firing.
7).  Patterns: Many of the double-layer ceramic mugs come with patterns, such as company logos, photos and so on. Usually, there are 5 crafts to make the pattern appear on the top of the mug, period, including: decal, engraving, airbrush, hot stamping, sandblasting. For details, see: 5 Craft Profiles of Ceramic Mug Patterns
8).  Firing: The glazed blanks are put into the kiln for high temperature firing. The firing temperature of double-layer ceramic mugs is usually between 1140-1280℃.

4. Whether the double-layer ceramic mug is safe to use in microwave and dishwasher

Formal ceramic factory (such as Xinxiang ceramic factory) production of double ceramic mugs, will be in the stage of signing the contract, and customers to communicate in detail needs. The communication details include the demand for microwave ovens and dishwashers. According to the customer's needs, Xinxiang Ceramic Factory will adjust the glaze, flower paper and firing temperature of the double layer ceramic mug accordingly. If customers require customised double layer ceramic mugs that can be applied to microwave ovens and dishwashers, then we will use high temperature glaze, high temperature flower paper and high temperature baking. For details of whether the ceramic mugs are safe for microwave and dishwasher, please refer to: What kind of ceramic coffee mugs are not dishwasher and microwave safe?

5. How do I custom double wall ceramic mug?

Customising your own double walled ceramic mug can usually be done in the following steps:
Choose a design:
Determine the pattern, text or colour that the customer wants. You can use your own design or choose a ready-made template, or you can commission a designer from a professional ceramics factory (e.g., designer from Xinxiang Ceramics Factory), who will help customers design their ceramic mugs for free.
Find suppliers:
Search online for custom ceramic mugs manufacturers or platforms, or you can also customise double layer ceramic mugs through nearby physical ceramic factories.
Confirm Samples:
The ceramic factory will make samples based on the requirements provided by the customer. Based on the samples, customers will determine whether they meet their needs.
Place order for production:
After confirming the design and samples, the order is placed and payment is made.
Waiting for delivery:
Generally customised products need a certain production time, which is roughly 20-45 days depending on different requirements and quantities.
Precautions
Ensure the copyright issue of the design and avoid using unauthorised patterns.
