Flowers in a Glass Vase

Mignon's Flowers in a Glass Vase at the Mauritshuis allows a technical comparison with his metal vase works: the glass vase introduces a transparency challenge — the painter must render the stems visible through the glass, distorted and refracted by the water within — that the metal vase does not require. Dutch painters from de Heem onward used glass vases as opportunities to display this specific optical accomplishment, making it a signature test of still life skill. The 1670 date places this work in the same productive period as the nearby metal vase painting, and the Mauritshuis context — the museum holds both works — allows direct comparison of Mignon's approach to different vase materials. The flowers themselves would include the usual encyclopaedic assortment of Dutch floral painting: tulips, roses, poppies, convolvulus, and other species assembled from different seasons and regions.

The glass vase requires a fundamentally different technique from metal: transparency is rendered through thin, cool glazes that allow background tones to show through, while refraction of the stems is handled through deliberate displacement of the painted stem from where it would appear in water, following careful observation. The water level creates a horizontal boundary above which stems appear straight and below which they bend. Condensation on the glass exterior may be suggested through very subtle cool scumbling.
