Methods of production

Traditional craftsmanship...

Many things have changed in the production of gold leaf since the Middle Ages, but the basic principle has remained the same. You cannot outwit the physical laws and you can only obtain the specific ductility of gold when certain rules are obeyed. The ancient recipes for the various alloys are well-kept secrets. Alloy components are mainly silver, copper, paladium and platin.



…is combined with innovative methods of production

We use an electronic scale to regulate the weight as exactly as 1/10.000 gram.
Only by this procedure we can guarantee that always exactly the same product is obtained and that the gilder will receive the same shade at any time. At more than 1200 degrees the components are fused and then cast into bars of 4 cm width. It takes several steps to produce a goldfoil of 0,007 mm by the means of specialized mechanical rolls. This foil band is then cut into regular squares and placed between separating sheets.
After the first beating process the foil is already thinner than 1 µ


It is then cut into squares again and placed into a gold-beater’s mould containing 2000 leaves made of high standard synthetic material. The leaves are prepared with a special material to allow a gliding process. In the gold-beater’s mould the gold-leaf is extended from 16 cm2 to 196 cm2. The automatic beating machines work with various beating patterns according to the grade of extension of the leaves.


We would like to point out that all machinery necessary for production is developed and built in an own department by NORIS BLATTGOLD themselves.
Once the required thinness of 1/7000 mm is obtained, hand work is applied again.


The »cutting« of the gold-leaves and qualitiy control is carried out by women with skilled hands and trained eyes.
