The sample size is relatively small, particularly for certain object categories and time periods, limiting the generalizability of findings about specific alloys and practices.
The lack of comparable data from neighboring regions, especially for the later periods (Ha B1 and Ha B3), makes it difficult to assess if observed trends are regional or more localized.
Over-reliance on Typology
The paper relies heavily on typological and distributional analyses, which can be subjective and don't always provide definitive proof of production location. Independent confirmation through craft production debris analysis would add more scientific weight.
Incomplete Analysis of Mixing/Recycling
While the paper acknowledges the possibility of mixing and recycling influencing metal composition, it doesn't fully explore this, potentially oversimplifying the interpretation of the data. More in-depth analysis is needed.
The lack of analysis of sulfur, a key element in copper sulfide ores, makes it difficult to have a comprehensive view of ore composition.
