Frosted glass is generally more expensive than regular glass. This is due to the additional processing required to create the frosted effect. Frosted glass is produced by applying a chemical or sandblasting process to the surface of the glass, which alters its transparency and adds texture. The process of creating frosted glass involves more steps and materials, which contribute to its higher cost.

According to a report by the Glass Association of North America, the cost of producing frosted glass can be up to 30% higher than that of regular glass. This is because the manufacturing process for frosted glass is more complex and requires specialized equipment. For instance, chemical etching or sandblasting machines are necessary to create the desired texture on the glass surface. These machines are not only expensive to purchase but also to maintain.

Moreover, the quality of the frosted glass can vary based on the level of opacity and the consistency of the texture. Higher quality frosted glass, which offers better light diffusion and a more uniform appearance, is often more expensive. The cost of raw materials can also play a role, as certain types of glass may be more expensive to produce due to their composition or thickness.

In summary, the additional processing and materials required to create frosted glass contribute to its higher cost compared to regular glass. The complexity of the manufacturing process, the need for specialized equipment, and the potential for higher quality variations all contribute to the price difference.
