Chemical and Mechanical Characterization of the Alternative Kriab-Mirror Tesserae for Restoration of 18th to 19th-Century Mosaics (Thailand).

Kriab-mirror tesserae are a type of lead-coated mosaic mirror found in most archaeological sites and antiquities dating back to the 18th century in central Thailand. The need for restoration work has prompted the search for alternative mirrors with similar characteristics to the ancient ones. Prototypes of alternative lead-coated mirrors were successfully used to restore a variety of archaeological sites and artifacts, demonstrating their potential application in heritage conservation and restoration work.

Preparation and characterization of lithium disilicate-fluorcanasite glass-ceramics for dental applications.

The purpose of this research is to discuss the preparation, characterization, and characteristics of lithium disilicate-fluorcanasite (LF) glass-ceramics in order to develop new dental glass-ceramics. A typical melt quenching method was used to produce the lithium disilicate (LD) and fluorcanasite (FC) types of glass. Following that, the LD and FC glass frits were combined and remelted in the following LD:FC ratios of 100:0, 0:100, 75:25, and 50:50 wt%, represented by S1, S2, S3, and S4, respectively.
