Are you wondering why each glass has a mysterious number on the bottom? Let's find out the secret behind these famous numbers.
History and origin of Duralex® lenses
Founded in 1945 in La Chapelle-Saint-Mesmin, France, Duralex® quickly established itself as a benchmark thanks to its products in remote tempered glass, renowned for its strength and durability. The glass we offer on our website is manufactured in La Chapelle Saint Mesmin near Orléans, before finding its way into countless homes, from family kitchens to school canteens.
The urban legend of Duralex® numbers
The curious story of the numbers at the bottom of Duralex® glasses originated in French canteens, where children created an endearing legend: according to this playful tradition, each number corresponded to the real age of the child using the glass. Looking at the bottom of the glass has become a daily game for schoolchildren, adding a playful dimension to this convivial moment.
The real purpose of the numbers at the bottom of Duralex® glasses
More than a charming anecdote, these numbers have a precise function: they are linked to the authentication process of the moulds used to manufacture our Duralex® glasses. Each mould is identified by a unique number, and it is this number that is discreetly inscribed on the bottom of each glass. This meticulous practice helps to guarantee the authenticity and exceptional quality of all our products.
Details of the role of numbers in mould authentication
As mentioned above, the numbers on the bottom of Duralex® glasses actually serve to authenticate the moulds used in the manufacturing process. Each mould at the La Chapelle-Saint-Mesmin factory is identified by a specific number, carefully engraved on the bottom of the associated glass, so that in the event of a defect or problem, we can quickly identify and replace the faulty mould.
The importance of this practice for traceability and quality
This method plays an essential role in the traceability and quality control of Duralex® lenses. It makes it easy to trace the origin of each product, ensuring constant compliance with the high standards we have set. In this way, each glass product is guaranteed to be of French origin and of exceptional quality.
In short, the numbers engraved on the bottom of your glass are not there just for the fun of it, but above all out of a concern for quality and customer satisfaction. By ordering from our site, you are choosing tradition, French quality and a unique story engraved on the bottom of each glass.
