The secret agents of sparkle

Known only by a handful of trusted employees, these recipes with their long lists of coloring agents are any glassmaker’s most valuable asset. And Preciosa has… well, a few.

Preciosa’s portfolio of premium glass and crystal products is incredibly diverse and part of what makes them premium is their apparent consistency.

Take our signature clear Crystal color, for example. Whether the batch is melted to produce size ss16 chaton roses or the long, vine-like arms of a chandelier, the color must look exactly the same. And although the end result is supposed to be identical, the recipes for these batches differ considerably. The intended finished product determines the specific ratio of ingredients, required to achieve visual consistency across our vast portfolio.

We are talking about decades of experimentation and development, which is what makes each recipe so invaluable and we believe there are things that we can achieve with glass that no one else in the world can. With the offer of an astounding 25,000 shape-size-and-color combinations, we require more glass recipes than any one person can keep straight.

Consistency

of colors is big part of what makes our products premium.

“Not only do we have to factor in the final use of the glass, we must also consider other factors, such as desired cooling temperature and the environmental implications of every ingredient,” says Květa Sázavová, Preciosa color specialist.

This depth of knowledge and intuitive knack for knowing how a procedure later in the production process may affect the color of the glass is not learned overnight, we are talking about decades of experimentation and development.
