The batch is a mix of three main components : sand, soda ash and limestone to which a quantity of cullet (crushed glass) is added. The raw materials are transported by barge or lorry to the mixing plant and thereafter by lorry to the various furnaces.
The production of a new mould involves a number of different processes : turning, milling, electro-erosion, adjusting and polishing.
The perfect quality of the mould, in direct contact with the glass, determines the optimum quality of the finished product. The mirror-like polish of our steel, makes perfect glass clarity possible, and the mould maintenance workshops insure permanent availability of clean moulds for the manufacturing machines.

Decoration
At ARC INTERNATIONAL , the decoration of products is achieved with a silk-screen process. A stainless steel screen is fitted onto the silk-screening machines. The enamel paint applied on these screens , or stencils, has a particular property : as soon as it comes into contact with glass , it hardens. The items are then annealed, fusing the decoration onto the glass permanently
Packaging
Because of the vast number of products available, the packaging is mainly done manually. Some of the items are also packed in bulk : these items are either unfinished or destined to be decorated and will be repacked later.
