Polish Glass Mark

The following mark has been very elusive in finding it's owner but alas, I have found the manufacturer.

Violetta Crystal Glass Works

History of Violetta Crystal Glass Works

Sadly, as of July 2008, "the shareholders of the Violetta Crystal Glass Works of Stronie Śląskie have decided to wind down the company, unable to cope with growing gas and electricity prices, upward pressures on wages, and the strong złoty. 460 persons now employed by Violetta will be made redundant. The plant makes an assortment of products from blown, coated, painted, and hand-engraved glass."(1)
