How do temperature fluctuations affect adhesives in stone sculpture repairs?
Temperature fluctuations can significantly impact the performance of adhesives used in stone sculpture repairs. When exposed to varying temperatures, adhesives may expand or contract, leading to weakened bonds or even failure. Thermal stress can cause cracks or delamination, especially in materials with different coefficients of thermal expansion. Additionally, extreme heat or cold may alter the adhesive's chemical properties, reducing its elasticity or curing time. For long-lasting repairs, conservators must select adhesives designed to withstand environmental changes and apply them under stable conditions. Understanding these effects ensures the durability and integrity of restored stone artworks.
