| Résumé : |
Holiday Pigments has developed an ultramarine blue to satisfy plastic bottle processing requirements.
One of the most ancient and revered of pigments, ultramarine blue has a distinctive and irreproducible colour. Already used extensively in food packaging, new grades have been developed to meet the tough demands of new plastics moulding techniques including, mineral water bottles, passing strict organoleptic tasting tests.
The Ancient Greeks regarded blue as the ultimate colour of perfect peace and purity, sacred to them as the blue of calm seas in mid-summer - halcyon days. They revered the kingfisher ; the brillant flash of blue from the European kingfisher's wing reminds us of this and the genus of kingfishers is also named Halcyon.
The rare mineral lapis lazuli was the original ingredient for this blue heritage and created the colour adored by artists from Egyptian pharaohs, through classical antiquity and the Renaissance to the present day. Until the 19th century, the only process to extract the pigment was expensive and complicated. In 1828, the first economically viable, synthetic version of ultramarine blue to reproducce lapis lazuli was discovered by Jean-Baptiste Guimet and started the modern industrial process. |
