Colourful Church Stained Glass Poster

This beautiful religious and colourful stained glass design is from The Cathedral Church of St. John the Divine, Amsterdam Avenue, New York, NY, USA. Stained glass is made by adding metallic salts during its manufacture process. The coloured glass is crafted into stained glass windows by small pieces of glass that are set up to form patterns or pictures, then held together by strips of lead and supported by a stiff frame. Stained glass can last as much as 75-150 years!
