Study on the Composition Analysis and Identification of Ancient Glass Products
Authors: Li Shirui
Published: February 2023

The Silk Road was an important channel for cultural exchanges between ancient China and the West, and glass was a precious material evidence of early trade exchanges. Early glass was often made into ornaments and introduced into China. After absorbing its technology, ancient Chinese glass was made locally, similar to its appearance but different in chemical composition. Due to different fluxes added during refining, the glass can be divided into lead barium glass and potassium glass, ancient glass is easily weathered by burial environment. In the weathering process, due to a large amount of exchange between internal elements and external elements, the proportion of their components changes, which affects the correct judgment of their categories. The research on the relevant properties of ancient cultural relics is a major topic in the field of archaeology in China, which is of great significance. There are a number of relevant data on ancient glass products in China. Archaeologists have divided them into two types: high potassium glass and lead barium glass.In order to explore the relevant properties and chemical composition changes of these glass relics before and after weathering, this paper analyzes the classification rules of high potassium glass and lead barium glass; The classification results were analyzed for rationality and sensitivity.

Taking Rights Seriously? Recent Shifts in Procedural and Substantive Matters of the Thai Constitutional Court
Authors: Atipiboonsin Apinop
Published: February 2023

The Thai Constitutional Court has recently dealt with more cases concerning constitutional rights such as those involving abortion and same-sex marriage, gaining widespread public attention similar to its many cases on political issues. This new development may show that the Court has now performed its role as a constitutional guardian and bulwark of rights. But the expansion of the caseload on rights may promote judicial activism and thus indicate a new strategy for the Court to be more powerful. This article looks at both the substantive changes in the jurisprudence of the Court as well as the procedural adjustments in recent court cases to determine the extent to which the Court has transformed itself to the ideal image of a great constitutional court in a comparative context. The Article analyzes all constitutional rights cases decided since 2019 to gauge the overall performance of the Court. Moreover, the Article also provides some examples of cases that seemingly protect constitutional rights but simultaneously expand the powers of the Court in the future. The analysis then suggests that while the Court might have facially helped protect more rights, it comes with a cost of a potentially even more active and political Court.
When Queer Emotions Meet the Constitutional Promise
Authors: Thongprasop Paweenwat , Pechnil Papawin
Published: February 2023

In classical constitutionalism, constitutional courts are dedicated guardians of the law, acting to promote fundamental rights. However, during an anticipated transition to democracy after the 2019 general election, substantial changes occurred in the pattern of judgments by the Constitutional Court of the Kingdom of Thailand (CC). These happened amidst popular demand for a democratic regime based on the rule of law. By squeezing heteronormative and royalist-nationalist ideologies into its legal reasoning, the CC has violated the constitutional rights of Thai citizenry and created a normative cosmos in which all forms of otherness are disregarded.
This article reads a utopian fantasy of Thainess in the Constitutional Court Decisions Nos. 19/2564 and 20/2564 in tandem with selected popular cultural texts on concepts of dystopian constitutionalism and queer jurisprudence. The goal is to analyze how disenfranchised voices neglected by the Court’s metanarrative may express queer negative emotions such as anger and fear, disclose the downside of constitutional promise, and offer playful readings of constitutional ideas and practices as Thailand struggles to attain the popular definition of constitutionalism.
