Answer:
The correct answer is a. lead strips
The H-sectioned lead strips are in charge to assemble the small pieces of glass, but also will prevent rattling and make the window waterproof.
Explanation:
The stained glass windows are a millennial artcraft, which was firstly used in church constructions and it's used nowadays in a broader range of applications. After the discovery of glass making and the color findings using metal additions into its craft, artisans and artists have used stained glass to light in the temples, but also have constructed religious narratives to decorate them.
The Romanic Styled temples, which go back to the Early Middle Ages, were very solid and dark constructions. Windows were a need to bring light to indoors and by the end of that artistic period appeared the first rosaceas, which were round-shaped stained glasses, adorned with religious thematic colored windows.
To assemble them, artisans have used lead strips made in metal. They would joint the different glass parts but also protect them from weathering. As soon as this technique was improved and spread, stained glass windows got even larger and wider. By the end of the Late Middle Ages, when the Gothic style was in vogue, bricks walls were being substituted by large stained glass.
We can notice it whether in English Gothic Churches, but mostly in the French ones. The Notre Dame Cathedral was one of a sample of how stained glass could be applied on large scale and in huge constructions. Soon its style was a model to other Gothic Churches around Europe.
But the climax of the stained glass churches we can consider as the small temple of Saint Chapelle in Paris, where all its walls were made with stained glass.
