Glass vs. Ceramic: What's the Difference?

By Janet White || Published on December 28, 2023
Glass is a hard, often transparent material made from silica, while ceramic is an inorganic, non-metallic solid prepared by the action of heat.

Key Differences

Glass, a versatile material commonly used in windows, is known for its transparency and resistance to weathering. Ceramic, on the other hand, is often used in pottery and tiles due to its heat resistance and durability.
Glass is typically formed by rapidly cooling a liquid silica mixture, giving it its characteristic smooth surface and clarity. Ceramics are created through the process of firing clay at high temperatures, resulting in a range of textures from porous to highly polished.
In terms of thermal insulation, glass generally conducts heat more than ceramic, making ceramic a better choice for applications requiring heat retention, like cookware.
Glass is often recyclable, contributing to its sustainability. Ceramics, though durable, are not as easily recycled due to their varied compositions.
In terms of artistic expression, both materials offer vast possibilities. Glass is used in intricate designs and stained glass art, while ceramics have been central to pottery and sculpture for millennia.
