These days, windows have been modernised into sleek designs that feature clean lines and flat surfaces. This is a striking contrast to old glass windows, which usually stand out due to their wavy characteristics.

If you have an old glass window, consider yourself lucky. Even though the images behind the glass may seem distorted, it is not a sign of damage. Instead, the waviness has something to do with the manufacturing process back in the days.

In any case, it is possible to tint old glass windows is possible, but there are a few things that you first need to know:


2 Types of Old Glass Windows

In the 19th century, there were two types of glass used for windows:


1. Crown Glass

Crown glass is an early type of glass that features a circular shape. It is made in front of a furnace to keep the glass hot and fluid for easy forming. Manufacturing crown glass involves blowing and spinning. However, the popularity of crown glass quickly faded because of its awkward nature, which paved the way for cylinder glass.


2. Cylinder Glass

Cylinder glass is similar to a drinking glass today, yet it comes with ripples and waves. Back in the old days, cylinder glass was manufactured in a cylindrical shape and in glass sheets. It became popular because it can accommodate larger window panes, which eliminated the need for crown glass pieces.

If you are still using an old glass window today, it’s easy to think that it is damaged due to its wavy features. The thing is, it’s not. The waviness is part of its natural charm that it takes from the ancient days. In fact, a lot of people enjoy the unique designs and patterns of old glass windows because they tend to stand out.
