Which obstacle complicated large-scale bronze axe production during the Early Bronze Age Mesopotamian Uruk period?

💡 Explanation

During the Early Bronze Age Uruk period, achieving homogenous tin distribution was difficult because tin was less available than copper. Improper mixing caused compositional variation and thus weakened axes. Therefore non-uniform axes resulted, rather than the other consequences which involved separately controlled metallurgical parameters.
