Cold-stamping - A short-lived bottom stamp

If a base mark is not embossed into the mould of a porcelain item as an underglaze mark or as a relief, the application of the base mark is understood to be a manufacturing process. In the conventional sense, a sliding image is then usually applied to the porcelain and fired a second time.

Cold stamping is different. Cold stamping involves applying the base mark to the finished body using a simple and very inexpensive stamping process. The porcelain is not fired again for cost reasons. Although the colour is usually reasonably dishwasher-resistant, it disappears after just a few rinses.

For porcelain and ceramics used in private households, such as the IKEA goods shown in the video, this may not matter. However, professional users - hotels, restaurants and catering - should urgently ensure that the base mark is not only stamped but also burned in to ensure traceability. This can be easily determined by carefully scratching the bottom mark with an object (cent piece, knife, etc.).

If parts of the floor mark come loose, we strongly advise against commercial use!
