This gorgeous vase made in Holland by 'Kunstaardewerkfabriek St. Lukas', Utrecht stands 5" high by 5" in diameter by 2" at the rim. It is an earthenware clay, a delicately lightweight vessel, covered in an awesome lustrous glaze in purple with random streaks of white glaze, all covered in a magnificent gold lustre and oil-spotted sheen. The oil-spotting shows green in the images, which is very exaggerated in the photos, and really not obvious in hand. I only see the green when rotating this pot in my hand, and it is from the oil-spotting. The last three images are on my deck outside, with reflection from the deck bannisters. This pot is deep purple and oyster white. The glaze is quite fluid in its presentation, with simply beautiful character. This vase, according to my research was fired three times, and apparently gold and silver powders were added to the glaze formula, which adds to its lustrous finish. This vase is marked in an ink stamp on the underside 'St. Lukas, Utrecht, Holland', along with a shape number that looks to be '46', and there is a 'K.O.' notation in glaze slip, which apparently is a glaze code, which is called 'Storm' by one online listing. Most of the vessels in this glaze character appear to be earlier glazes than later, so we thnk c1909 or so. We've had early Zsolnay lustre pots over the years, and this vase is of the same quality. It is in original studio condition, with some superficial stray marks, not sure if they are handling marks, or actually glaze nuances from the firing process. They are not scratches into the glaze surface. The underside shows a small pooling of white glaze on the foot, which was ground down at the factory for a glaze drip. This is a stunning Dutch lustre pot!
Online research reveals that St. Lukas, Utrecht was founded as 'Kunstaardewerkfabriek St. Lukas' in 1909 by brothers-in-law G.J.D. Offermans and A.S. Enthoven. Their entre into pottery came during the Dutch art nouveau movement called "de Nieuwe Kunst". The St Lukas name came from the painters, gilders and glassmakers guild whose patron saint was Saint Lukas. Offermans was the technical expert and Enthoven had the financial contacts to create and support the business. Metal oxides created a pearly sheen to the lustre glazes, predominantly yellow, blue and purple lustres with a golden sheen. The term used was “reflet métallique”. Each piece was triple fired. In its heyday, the factory produced extremely high quality decorative pottery and specialized in gold lustre glazes. Offermans, who was previously employed at De Porceleyne Fles in Delft and at Haga in Purmerend, had made a name for himself with his lustre glazes. It was a very expensive glaze method, with an iridescent layer and added gold or silver powder to the enamel mixture, which produced superb lustrous glaze finishes. The factory closed in 1923.
