Abstract In the study of archaeological glass beads, the manufacturing process of eye beads is of great significance and value. This is a focused research investigation about eye beads. Based on previous research published 2019 [3] , one of the eye beads unearthed in Shampula Cemetery was proved to be embedded manufacture. In this paper, several kinds of eye beads were studied and compared. With the results, a new manufacturing process for certain eye beads is discovered and compared by X-ray Computed Tomography (CT) technique. The shapes of air bubbles, the distribution of the air bubbles, and especially the direction of the eye part in the beads, were analyzed by CT. Two kinds of pattern of eyes were discovered based on the CT results and the appearance of specific eye beads. Thus, the manufacturing process of eye beads can be divided into two types. The difference between the two types is the placement direction of the eye parts. In addition, the manufacturing process of eyes produced either raised or embedded appearances of the eye beads. The squeezing direction was found to be perpendicular to the long axis of the elliptical bubbles in the bead body through the air bubble shape of the three samples producing raised eye beads and embedded eye beads which appear like human eyes. Analysis of the technological factors produced insights into the beads-making process within a historical context so as to provide better data for the origin of this particular batch of eye beads.

计算机断层扫描技术在眼珠制造技术分析中的应用

摘要 在考古玻璃珠的研究中，眼珠的制作工艺具有重要的意义和价值。这是一项关于眼珠的重点研究调查。根据之前发表于2019年的研究[3]，香普拉公墓出土的一颗眼珠被证实为嵌入式制造。本文对几种眼珠进行了研究和比较。根据这些结果，通过 X 射线计算机断层扫描 (CT) 技术发现并比较了某些眼珠的新制造工艺。通过CT分析气泡的形状、气泡的分布，特别是珠中眼部的方向。根据CT结果和特定眼珠的出现，发现了两种眼型。因此，眼珠的制造工艺可分为两种。两种类型的区别在于眼部部件的放置方向。此外，眼睛的制造过程产生了眼珠的凸起或嵌入外观。通过三个样品的气泡形状，发现挤压方向垂直于珠体中椭圆形气泡的长轴，产生了像人眼一样的凸起的眼珠和嵌入的眼珠。通过对技术因素的分析，可以深入了解历史背景下的珠子制作过程，以便为这批特定眼珠的来源提供更好的数据。眼睛的制造过程产生了眼珠的凸起或嵌入外观。通过三个样品的气泡形状，发现挤压方向垂直于珠体中椭圆形气泡的长轴，产生了像人眼一样的凸起的眼珠和嵌入的眼珠。通过对技术因素的分析，可以深入了解历史背景下的珠子制作过程，以便为这批特定眼珠的来源提供更好的数据。眼睛的制造过程产生了眼珠的凸起或嵌入外观。通过三个样品的气泡形状，发现挤压方向垂直于珠体中椭圆形气泡的长轴，产生了像人眼一样的凸起的眼珠和嵌入的眼珠。通过对技术因素的分析，可以深入了解历史背景下的珠子制作过程，以便为这批特定眼珠的来源提供更好的数据。
