Azulejo vs Stained Glass
アズレージョ / ステンドグラス
Both sit in Ornament, so the question is not what they belong to but how they behave. One is style and the other technique. They are reached for with some of the same intent, which is where they get confused.
Azulejo
Portugal's blue-and-white tile works as the skin of architecture, opening story, map and ornament onto the street until the city itself can be read as a printed plate.
Stained Glass
Divides light with colored glass and lead lines, making contour itself structure and story.
| Azulejo | Stained Glass | |
|---|---|---|
| Era | 15th century– | medieval–present |
| Family | Ornament | Ornament |
| Kind | Style | Technique |
| Cues | Blue-and-white tile / Narrative panels wall-high / Repeating pattern / One body with the building | Lead contours / Transmitted color / Geometric division / Jewel tones |
| Best used for | Using a building's wall as a large plate the passerby can read · Covering rooms floor to ceiling in repeats for coolness and continuity | Symbolic images with light in the leading role · Organizing complex narrative into panels |
| Type | Fire the inscription in the same blue and frame it into the wall | Concise letters that hold against the contours |
| Composition | Set the tile grid first, compose so breaks fall on the joints | Divide color fields with lead lines around a central figure |
| Material | Cobalt blue on white glaze, judged with the gloss reflection included | Deep red, blue, gold, transmitted light, black joints |
| Caution | Laying a large picture out without regard for the joints misaligns grid and drawing, and the wall looks like a printed sheet pasted on. | Not just translucent gradients. Design the structural lines that carry the color fields. |
