Pax Romana makes as much materials as possible themselves. Some materials are too complicated to make, and are made in collaboration with specialists. Sometimes materials are bought, to then be subsequently updated and modified to match archaeological finds or historical images.

The production of many materials doesn’t come easy. It often takes many hours to achieve the desired result. For example, if one wants to make a coat of mail, it will take a few months to half a year to make one.

Before new materials are created, all known historical and archaeological sources are collected. Materials without any evidence of historical use are to be avoided. On the other hand new archaeological information is used as much as possible to create new materials, but also to update the current materials. To support this, Pax Romana relies on three archaeologists as club members, but also keeps close contact with archaeologists in the country and abroad.

Through “experimental archeology” the knowledge of archaeological materials is tested. Replicas of these materials are used by Pax Romana and tested on whether the scientific interpretation is correct.
