What materials are Mezuzahs made from?

Mezuzahs, sacred Jewish objects affixed to door frames, are crafted from various materials. Traditional mezuzahs are primarily made from kosher animal parchment, known as klaf, which is derived from the hide of a kosher animal like a cow. The klaf undergoes specific preparation and inscription processes by a trained scribe, ensuring the precise writing of sacred Hebrew verses. Additionally, mezuzahs can be fashioned from alternative materials such as metal, glass, wood, or even plastic. These alternative options provide a wider range of styles and designs to suit different preferences or decorative purposes. However, it is important to note that regardless of the material used, the klaf containing the sacred verses remains the core aspect of a mezuzah's function and sanctity.
