As manifold as  shape and conservation degree of burned archaeological structures are, as manifold are the techniques of archaeomagnetic sampling. Various laboratories have developed different techniques depending on their experience and their possibility of sampling burned archaeological structures. Below you will find description of some of these sampling techniques for taking small oriented samples:

Archaeomagnetic Sampling: Protocols for the BAN  Geomagnetism Laboratory, Sofia, Bulgaria (Mary Kovacheva & Andy I.R. Herries)
Sampling procedures and sample preparation adopted at the Laboratory of Palaeomagnetism of the Universidad Complutense de Madrid, Spain (Gianluca Catanzariti)
Sampling methods and sample laboratory preparation at the Department of Archaeological Sciences, University of Bradford, United Kingdom (Assunta Trapanese)
