Ceramic does not conduct electricity under normal conditions. It is one of the most reliable electrical insulators known to materials science, used in everything from spark plug housings to high-voltage power line insulators precisely because electrons cannot move freely through its tightly bonded atomic structure. That said, the full picture is more nuanced. Certain advanced…
Ceramic engineering is one of the most technically demanding and materially diverse fields in engineering, yet most people have never heard of it. It covers everything from the clay body in a coffee mug to the heat shield tiles on a space shuttle. This guide covers what ceramic engineering is as a discipline, what ceramic…
A small piece of spark plug ceramic can shatter a car window in under a second, yet that same window survives a full-force punch from a grown adult. The reason comes down to one physical property: hardness versus brittleness, and how a tiny shard of alumina ceramic concentrates force at a microscopic point no larger…
Ceramic cannot be recycled through your curbside bin, and most municipal recycling programs reject it entirely. That single fact shapes every disposal decision you will make with broken mugs, old tiles, cracked pots, and fired ceramic waste from a studio. This guide covers the full scope of ceramic recyclability: why fired ceramic resists conventional recycling,…
Terracotta is ceramic. It belongs to the earthenware category of ceramics, fired at low temperatures between cone 010 and cone 01 (1657°F to 2109°F / 903°C to 1154°C), and it represents one of the oldest continuously used ceramic materials in human history. The confusion around terracotta’s classification comes from how the word is used. In…
Stoneware is a ceramic. It is not a separate material category that exists outside the ceramic family. This single clarification resolves most of the confusion people carry into pottery studios, kitchenware stores, and materials science courses. Stoneware is one specific type of ceramic, defined by its firing range of cone 6 to cone 10 (2232°F…
