What type of edges should mirrors have when using J-molding?

When using J-molding for mirrors, it is crucial for the edges of the mirrors to be ground. Ground edges are smoothed and shaped to eliminate sharpness and create a safer, more finished appearance. This process not only enhances the aesthetic quality of the mirror but also minimizes the risk of injury or breakage, as the edges are less likely to splinter or chip.

Using ground edges allows for a better fit within the J-molding, creating a snug and secure installation that prevents the mirror from rattling or moving. This is particularly important in environments where stability is essential, such as bathrooms or commercial spaces. Ground edges also enhance the reflective qualities of the mirror, allowing for a clearer view without distracting imperfections that might occur with other edge treatments.
