Glasfabriek Leerdam - A.D. Copier - Dish - Crystal - Vitrica Unica

Where other vitrified items are considered serica due to their irregular tincraquelé, this very special deep blue specimen can be regarded as unique. With the usual diameter of 30 cm, it has a convexity up to a scale of 4 cm high. In the center, there is a black floral motif and a mark unknown to me. Along the edge, stylized birds are engraved. There are no damages, but visible impressions from the tongs used during production are present. Perhaps this was a practice piece for both the engraver and the glassblower? In any case, there is no second one like this.
