The two brothers Gerhard and Arie Jacob Nagtegaal start a factory in Gouda for the production of refractory material under the name of Firma Gebrs. Nagtegaal.
Arie Jacob leaves the company and transfers his share to his sister Anna Maria.
Gerhard's son Gerard Cornelis and the latter's brother-in-law Eduard Carel van den Bovenkamp buy-out the founders of the company and focus on supplying to the petrochemical industry, which is growing rapidly thanks to the post-war reconstruction.
Firma Gebrs. Nagtegaal becomes an NV (Dutch limited liability company) with more than 60 employees.
Partnership with De Porceleyne Fles leads to a new name: NV Gouda Vuurvast, Verenigde Vuurvaste-Steenfabrieken. New offices and a modern laboratory are built on the company's site. The factory is already using a tunnel oven. Regular customers for the company's refractory bricks and concrete include Shell, Esso, Stork, Philips, Ketjen, Werkspoor, Koninklijke Sphinx, Koninklijke Mosa, the Royal Netherlands Navy and the NS (Dutch Railways).
Acquisition of the Oven Building department of De Porceleyne Fles. By now the company has more than 150 employees.
Acquisition of the French company Carbonisation Entreprise et Céramique (CEC). This in turn later became part of the cement producer Lafarge.
De Nagtegaal and Van den Bovenkamp families buy Gouda Vuurvast back from Lafarge.
Gouda Vuurvast is listed on the Amsterdam stock exchange.
Acquisition of the Belgian oven builder Selanco Vuurvast in Schoten leads to the formation of Gouda Vuurvast Belgium.
Gouda Feuerfest is established in Germany.
Gouda Vuurvast becomes part of the RijnDijk Groep, which changes its name to Andus Group at the beginning of 2009. The group has four divisions working in the oil & gas, steel construction, refractory and process industries.
Andus Refractories has five independent operating companies: Gouda Refractories, Gouda Projects, Gouda Vuurvast Services, Gouda Vuurvast Belgium and Gouda Feuerfest (Germany).
