How Ceramics Are Made?
The first use of ceramic cookware and pottery is noted to be in 9.000 BC, which was used for holding, storing and eating food. Since then, the ceramics production has steadily increased and today we have the best cooking technology that anyone could imagine.
We know how the ceramic cookware and utensils were made in the ancient times, but what about today’s production and processing? If you want to know, we will tell you all the basics and what paths did your favorite ceramic pan go through.
Besides these processes, ceramics can be machined with special machines and tools and the process is known as green machining. The best processing method for ceramics is a combination of sintering with forming. So we have a process summarized in 4 steps: preparing the starting materials, shaping, sintering and finishing.
Sintering literally means firing the materials by exposing them to 1800-2000oC for days and weeks. Then this is followed by hot pressing. Hot isostatic pressing, chemical vapor deposition and reaction bonding. The finishing part includes increasing the dimensional accuracy, improving the surface, and making minor changes in the geometry of the product.
Over at Wilson Cutlery the manufacturers use zirconia #4, unlike others that use zirconia #2.This actually provides more quality products and with 30% higher particle fineness. Their processing methods and different techniques result in thick and sharp ceramic cutlery, more sanitary, healthier, and safe ones.
