Abstract

The surface characteristics of Zachery-treated turquoise stones have been studied in detail with a comparison of natural and plastic-impregnated turquoise. The SEM-EDS analysis exhibited that Zachery-treated turquoise was characterized by the uniform distribution of potassium element through the specimen and did not show the sharp crystalline $SiO_2$ facet and boundary phase which are common in natural ore. The potassium element shown in the Zachery-treated turquoise seemed to be occurred during the treatment process for the improvement of durability. The bar-shaped crystals observed in the pore was found to be a feature of Zachery treated turquoise and are expected to influence on their stability and durability, while the pore sizes in turquoise stones depends on the parameter of the treatment procedure.

Zachery 처리 터키석의 표면 특성을 일반적인 터키석 처리 방법으로 알려진 플라스틱 주입에 의해 처리한 터키석과 어떠한 처리도 하지 많은 천연의 터키석과 비교 분석을 하여 Zachery 처리 공정을 평가하였다. SEM-EDS 결과, Zachery 처리 터키석은 내부에서 칼륨의 균일한 분포가 관찰되었고 천연 터키석에서 보이는 날카로운 quartz 표면과 경계면을 관찰할 수 없었다. 또한 Zachery 처리 터키석에서 나타나는 칼륨은 내구성 향상을 위한 전체 처리 과정에 의해 발생하는 것으로 확인되었다. 기공에서 관찰되는 주상형의 결정은 Zachery 처리 터키석의 또 다른 특성으로 Zachery 처리 터키석의 내구성에 영향을 주며, 원재료의 기공 크기는 처리의 변수로 작용함을 확인하였다.
