Super Flint

Flint has good transparency, while super-flint offers the very best in clarity, often compared to crystal. Super-flint bottles tend to be of more substance, heavier, and often contain a deep base - 20-30mm - that gives the bottle a further feel of quality. Super-flint tends to be the choice of brands in the premium spirits sector, particularly those in the Vodka, Cognac, Brandy and Whisky categories.


Common Flint

Common Flint Glass has a slight green tint that can vary based on glass thickness and other factors. The tint is most apparent at the base and shoulders, where the glass is thickest, and is less visible when filled. Common Flint draws it's appeal from it's vintage look for certain applications.




For both custom designs and catalogue products, SAVERGLASS offers a wide variety of personalization options through variations in capacity, glass colors, and types of corking or decorative container engraving.





This solution involves adapting a customized ring finish to items provided it is compatible technically with the existing moulds. This can be a standardised finish, a special finish or even a finish that is personalised with peripheral debossing .



This solution requires only the development of bases plates or in certain cases blank base moulds. This extends options for placing individual engraved elements on the base plate or inside the punt.

This principle is used to place an engraved feature in a medallion located on a bottle shoulder . Through this ingenious design with removable inserts placed on a selection of wine bottles  this cresting technique is relatively economical because it does not involve the need of a full set of moulds.. Furthermore, this technique can be used to obtain incredibly precise definition and  is highly reproducible.




This involves creating a new set of blow moulds that are compatible with the blank moulds already featured in the catalogue.This allows personalization through engravings that can be placed anywhere on the shoulder, body, or the base of a container.


In some cases it is necessary to make full mould sets comprising blank and blow moulds, especially for :

  • Varying a particular shape that is unavailable in the product range
  • Modifying certain dimensions like height or diameter, or perceptibly changing glass weight
  • ​Making up a special finish whose dimensions are incompatible with existing tools.




"Bas Relief" is an ingenious solution that allows circular engraving to be positioned on the lower part of a bottle containing information such as the name of an area, geometrical friezes, or figurative scenes. 

As with the Cresting Insert option, SAVERGLASS has a series of mould sets for wine bottles designed with this technical principle to facilitate clients’ access to this type of feature
