the enamelling history in Norway.
was the name of an old ironworks, placed by the end of “Tistafossen”, a
waterfall in Tistedal, and this was 3 kilometres from the town Halden.
The products wrought iron, chains, nails and agriculture equipment was
renown as quality products.
But with sinking profitability did the leadership look for other materials
The choice fell on enamel on steel in form of kitchen and sanitary equipment.
Enamelled signs for practical purposes and advertising were also important
The production started up in 1907. Since the production was new in Norway,
skilled workmen had to be imported from Germany. And towards 2. World-war
collaborators with names as: Til, Holmann, Dieterich, Schröder, Hel, Krume
and Hetch were standing on the companys payroll.
Sverre who together with Willy started Hammerstrøm AS, worked on
Chatrineholm in two periods (1931-38 and 1956-65). He knew and worked with
most of these skilled and hard-working men.
As time went by, the competition from other materials like stainless steel,
aluminium and plastics was to strong, and the old rich in Traditions Company
had to close down in 1970.
Our company, Hammerstrøm AS, started up in 1965 with four employees. To day
34, and some of these have also been working at Cathrineholm.
As it tells from this short story, the enamel-industry in Norway has its
roots in Tistedal, and we like to se us as real born inherits from this
We will do our best to manage and develop further this inherit.
consists nearly the same raw material as china glaze, but it is much
stronger, this because it has steel instead of clay as base.
The enamel comes to us in shape of flake.
We mix it together with clay, chemicals and colour.
This will so be made to the right consistence by using mills. This is a
very important part of the quality and result of the enamelling process.
Dipping the product in floating enamel can do enamelling. What stays on
the product after it has been hang up and the surplus have dript of will
be the enamel.
This was the usual way to enamel. To day one can use electrostatic or
spray and combined with robot this is an efficient way to enamel.
It is the last method we use here at Hammerstrøm AS. It demands bigger
investments in equipment, but it increases the result and quality. You get
better control, and nicer look on the products.
The enamel then has to be dried, and so it is ready for being baking (heated
up to red-hot). This can be done in a “box” oven or like we have a
A good result is also depending much on skilled workmen.
In the same way as with the mills, the baking also has to be controlled
very close to get the best result. Black products are enamelled only once,
but colours have to have a layer of “prime” enamel first.
