The quality of raw materials is checked regularly by a certified laboratory. Internal quality inspections follow each production stage. Final manual quality controls take place before items are stored, e.g. to ensure compliance with our specified tolerances. The benefit for customers and staff: TAFELSTERN products do not contain any harmful substances, in particular no lead.
RESISTANT TO CHIPPING
Everyday catering requires professional tableware, particularly when it comes to resistance to chipping. Nothing is less appealing than chipped edges on plates or around the rims of cups. Hard porcelain is typically very resistant to chipping, although this can vary depending on the specific product design. This means your tableware remains in flawless condition.
RESISTANCE TO TEMPERATURE FLUCTUATIONS
TAFELSTERN’s hard porcelain tableware can withstand the heating rates and maximum temperatures for all standard commercial ovens, microwaves, combi-steamers and salamanders.
However, it is essential to avoid exposing hard porcelain items to abrupt temperature changes (T-shocks) of more than 220 K in either direction.
Important examples of this are:
- a hard porcelain item at a room temperature of 20°C is put into an oven that has been pre-heated to over 240°C.
- a hard porcelain item filled with a dish that has been frozen at -20°C is put into an oven that has been pre-heated to over 200°C.
- a hard porcelain item is pre-heated to a temperature of over 200°C then filled with a dish that has been frozen at -20°C.
- a hard porcelain item is heated in an oven to 240°C then placed on a cold surface (kitchen counter etc.) with a temperature of 20°C. It is best to place a thick kitchen towel in between or use a rack.
It is also recommended that porcelain items are placed on a rack in the oven and not on the hot floor of the oven.
The four temperature differentials of +/- 220 K specified here are based on previous empirical experience. Sudden exposure to changes in temperature above these values can result in hard porcelain items developing cracks.
Hard porcelain is produced using natural materials which are subject to variation. During the manufacturing process, the items are exposed to very high firing temperatures in order to achieve the necessary glaze thickness. This can result in different tolerances in terms of the volume, size or weight of individual items. TAFELSTERN imposes low tolerances so that, for example, the items can always be stacked as designed. The same is true for volume tolerances for cups and other containers. This avoids having to constantly readjust automatic coffee makers to handle different capacities.
Weight tolerance: - 5% / + 10%
Height tolerance: +/- 3%
Diameter tolerance: +/- 1.5%
As well as having a comparatively higher density than other ceramic items, hard porcelain also has the hardest, most abrasion-resistant glaze. This consists of the natural materials kaolin, quartz and feldspar. The temperature during glaze firing (2nd firing process) is crucial for the hardness of the glaze. The higher the temperature, the denser and more scratch resistant the porcelain item will be. For TAFELSTERN products, the glaze firing is done at over 1,400 °C, which results in a very hard, impact-resistant, shockproof glaze that is resistant to scratches and incisions. The hardness of the glaze is measured in Mohs: diamond = 10, hard porcelain = 8, vitreous china and bone china = 5.
Deposits, e.g. from cutlery or stainless steel surfaces in the kitchen, are caused because the metal is softer than the glaze. Metal deposits won’t damage the hard glaze and can be removed using a porcelain cleaner, e.g. Etolit.
Hard porcelain items from TAFELSTERN are suitable for use in the microwave, whether they are decorated or not. Some exceptions: items with embellishments using precious metals such as platinum, silver or gold must not be used in the microwave. This could result in damage to the decorative detail and to the equipment itself.
The capacities of jugs, cups and bowls are measured when full to the mark.
All TAFELSTERN decorations are made using water-based, in-glaze dyes. These are absorbed into the glaze during the overglaze (decorative) firing and combine to form a single entity with the glaze. This means the decoration is protected against mechanical and chemical impacts and the decorative details remain brilliantly vibrant even after many years of use.
All in-glaze decorations are suitable for dishwasher cleaning. This is also true for crockery where the glaze itself is a decorative feature (colour glazes).
Always use branded detergent and rinse aid and follow the manufacturer’s quantity recommendations.
If an insufficient quantity is used, starch residues can be left on the glaze which build up to create an unhygienic film. Undecorated items are always dishwasher-safe.
CARE INSTRUCTIONS FOR DECORATIONS
- Decorations that are marked with this symbol are particularly delicate and susceptible to scratching. We recommend protecting such items against potential mechanical stress as this can result in damage to the decorative details.
- Please stack plates and platters from the top and do not slide them sideways into each other. The base of plates and platters can scratch the decorated surface area.
- When stacking items for storage, we recommend interspersing with French terry, fleece or kitchen paper.
- A build-up of metal/cutlery deposits can occur on sandblasted surfaces because hard porcelain is harder than metal. These deposits are easy to remove using a sponge and a cleaner e.g. “Etolit”.
- Please do not expose sandblasted surfaces to any foods that can cause severe staining, e.g. spice pastes. These kinds of stains cannot usually be completely removed with a sponge and “Etolit”.
- Stains and any slight scratches to the high-gloss finish on metal-plated items should be tackled with a suitable silver cleaning product (liquid cleaner, silver polishing cloth).
Environmentalism is more than just a buzzword for TAFELSTERN, it is fundamental to our everyday lives. In February 2012 our company became one of the first in the global porcelain sector to be successfully certified under the international standards DIN EN ISO 14001 (environmental management) and DIN EN ISO 50001 (energy management).
TAFELSTERN’s durable tableware can be used for decades thus reducing waste. “Made in Germany” by TAFELSTERN represents compliance with the world’s strictest environmental regulations.

NOBLE CHINA is an innovative, thin, hard-paste porcelain that does not need any lead, cadmium or animal components. Fired at over 1,400 °C, this revolutionary porcelain compound is surprisingly hard-wearing, setting new standards in this regard. Despite being delicate in unglazed form, these items are remarkably resistant to chipping and unlikely to suffer damage to the glaze, which makes them extremely durable. The delicate, creamy bone-white hue adds to the impression of discreet elegance. The CREATE, DELIGHT and EATERY collections are produced using Noble China.
TAFELSTERN’s product philosophy is based on a simple but ingenious idea: the TAFELSTERN modular system. The creative possibilities are unlimited, you can combine items from across different ranges. You can add to your tableware at any time, easily developing and extending your crockery stocks. All tableware items can be freely combined. So basic ranges, such as AVANTGARDE, can happily coexist alongside highlights from the ESSENTIALS collection.
TAFELSTERN porcelain is resistant to chemicals, alkaline solutions and acids. This means the lead-free glaze will not be damaged and continues to meet all hygiene standards.
