利用扫描电子显微镜（SEM）研究了一系列公元前6000年至公元750年的伊拉克陶器碎片和公元前5000年左右的土耳其陶器碎片。该检查提供了烧制过程中形成的内部形态的信息，特别是关于玻璃化程度（玻璃相）和孔隙结构的信息1,2。玻璃化的程度为表征陶器的质量提供了一个有用的参数，因为它影响到几种物理特性（如硬度、强度、渗透性），这些特性与陶器可能被用于各种用途的适用性有关。此外，通过在已知温度下重新烧制陶器样品，并通过扫描电镜重新检查，确定玻璃化发生增加的温度，可以估计古代使用的烧制温度。
A SEQUENCE of pottery sherds from Iraq spanning the period about 6000 BC to 750 AD and two sherds from Turkey about 5000 BC have been examined using a scanning electron microscope (SEM). This examination provided information on the internal morphology developed during firing and in particular information on the extent of vitrification (the glassy phase) and the pore structure1,2. The extent of vitrification provided a useful parameter for characterising the quality of the pottery since it influences several physical properties (such as, hardness, strength, permeability) which are relevant to its suitability for the various uses to which it might be put. In addition by refiring samples of the pottery at known temperatures and determining, by re-examination with the SEM, the temperature at which an increase in the vitrification had occurred, it was possible to estimate the firing temperature used in antiquity.
