Peruslasi

Peruslasi is a Finnish term that translates to "base glass" or "basic glass." It refers to ordinary, unadorned glass used in a wide range of everyday applications. Unlike specialized glass types such as tempered glass, laminated glass, or decorative glass, peruslasi is the fundamental material from which many other glass products are derived. Its primary properties include transparency, brittleness, and a smooth surface.

In its simplest form, peruslasi is typically soda-lime glass, a common type of glass made from silica, soda ash, and limestone. This composition makes it relatively inexpensive to produce and easy to work with, making it suitable for mass production. Peruslasi is frequently found in windows, containers like bottles and jars, and simple tableware.

While peruslasi itself does not possess enhanced safety features or aesthetic embellishments, it serves as the foundational material that can be further processed. For example, it can be cut, shaped, and polished into various forms. Its inherent transparency allows for light to pass through, which is its most significant functional characteristic in many applications. The term emphasizes the unenhanced, fundamental nature of the glass before any additional treatments or modifications are applied.
