The authentication and display of historic porcelain sculptures in museums and galleries involves a meticulous multi-step process that combines scientific analysis with art historical expertise. Institutions typically begin with provenance research, tracing the object's ownership history through archival documents, collector marks, and historical records. Advanced technologies like X-ray fluorescence (XRF) spectroscopy and thermoluminescence testing help determine the chemical composition and age of the ceramic materials.

Conservators examine the sculpture's craftsmanship details - glaze characteristics, clay composition, and firing techniques - comparing them to known authentic pieces from the same period and region. Brushwork patterns, decorative motifs, and even microscopic tool marks provide crucial authentication clues. Many museums now employ 3D imaging and digital databases to create comparative references.

For display, museums implement strict environmental controls. Relative humidity is maintained between 45-55% to prevent cracking, while light levels are kept below 50 lux for sensitive pieces. Specialized display cases with vibration-dampening mounts and UV-filtering glass protect the sculptures. Some institutions use angled platforms or rotating bases to showcase intricate details without physical handling.

Contemporary galleries often combine traditional authentication methods with interactive digital displays, allowing visitors to explore high-resolution scans of porcelain marks and signatures. The most valuable pieces may be displayed in climate-controlled vitrines with inert gas environments to prevent chemical degradation. Through these comprehensive approaches, cultural institutions ensure both the preservation of historic porcelain masterpieces and their meaningful presentation to the public.
