Resistance and Hardness
Arthur Krupp porcelain has a very high degree of hardness, it is even harder than standard steel. This results from very careful firing, as porcelain is left even more than 50 hours in high-temperature kilns through different cycles. After drying, porcelain items are first fired at 1,000 °C for 8 to 24 hours. The second firing takes place after glazing at a temperature above 1,400°C for about 30 hours. Through the excellent fusion of ingredients, the porcelain acquires its characteristics of hardness, texture, lack of porosity and resistance to shocks and thermal shocks.
Resulting from the combination of three raw materials (kaolin, quartz and feldspar), porcelain has now reached a higher level of quality. The plant of the Group in Selb, Upper Franconia, is indeed renowned for its feldspathic porcelain, a special type of white porcelain that is very compact, resistant and shiny at the same time.
The peculiar white collections by Arthur Krupp stand out for the uniqueness of their perfectly smooth surfaces, which result from the perfect fusion of glaze with the porcelain structure. Skillful glazing and in-glaze firing are still one ofthe main qualities of the products as they preserve the collections over time.
In order to ensure quality, Arthur Krupp systematically monitors the manufacturing stages of its products by internally overseeing the process of procurement and preparation of raw materials, by maintaining know-how in mould production and by autonomously developing industrialisation for all its collections. The company also includes an analysis laboratory that can certify the high quality and safety standards of the brand by carrying out tests identifying the strengths and any weaknesses of a product. The monitoring, recording and control procedures adopted allow planning real time corrective measures for each production stage.
Arthur Krupp porcelain is food safe as it complies with the limits for lead and cadmium release set out by FDA regulations (USA), by DIN standard no.51031(EC) and the 84/500 ECC directive. The company scrupulously conforms to safety parameters not only to the benefit of the professional industry its products are intended for, but also, and foremost, of final users.
