Cameo Glass vs Stained Glass
カメオ・グラス / ステンドグラス
Cameo Glass comes from Vessel and Craft Techniques and Stained Glass from Ornament. They are reached for with some of the same intent, which is where they get confused.
Cameo Glass
Cased glass built from two or more layers in contrasting colours, where the outer layer is carved, cut or engraved away so the design stands out from the ground. Getty classifies it as a material rather than a period style. The image is not painted but left behind, and the thickness left standing is what decides how opaque it reads.
Stained Glass
Divides light with colored glass and lead lines, making contour itself structure and story.
| Cameo Glass | Stained Glass | |
|---|---|---|
| Era | Roman era– | medieval–present |
| Family | Vessel and Craft Techniques | Ornament |
| Kind | Technique | Technique |
| Cues | A pale image standing up in relief over a darker ground / Where the cut runs deep the ground colour shows through and the image sinks; only the thickest passages go fully opaque / The ground is one even colour and all the tonal range sits in the image / Edges are steps rather than drawn lines, so raking light throws a shadow off the image itself | Lead contours / Transmitted color / Geometric division / Jewel tones |
| Best used for | Building an image out of two stacked surfaces, where the edge is carried by a step and its shadow instead of a drawn line · Working in blind emboss or foil, where nothing is added in colour and the whole image has to come from difference in thickness | Symbolic images with light in the leading role · Organizing complex narrative into panels |
| Type | Cut the lettering out of the same layer as the image. Let the stroke width be a carving width, and avoid hairline faces. | Concise letters that hold against the contours |
| Composition | A wide field of one dark colour with a single pale image on it. Keep the ground plain and put nothing between the two. | Divide color fields with lead lines around a central figure |
| Material | Layers of contrasting glass with the outer one cut away. The thickness you leave standing gives the range from translucent to fully opaque. | Deep red, blue, gold, transmitted light, black joints |
| Caution | Copying only the light and dark contrast as two flat fills loses the translucent middle that depth of cut produces, and the result reads as cut paper. | Not just translucent gradients. Design the structural lines that carry the color fields. |
