What happens to the pastillage when exposed to high humidity?

When pastillage is exposed to high humidity, it tends to absorb moisture from the air. This absorption can lead to the pastillage becoming sticky, which undermines its structural integrity. Consequently, it may begin to lose its shape as it softens and adheres to surfaces, making it challenging to work with or maintain detailed designs. High humidity is particularly detrimental to pastillage, which is crafted to be hard and dry; thus, any increase in moisture negatively impacts its intended properties. This phenomenon is crucial for anyone working with pastillage to understand, as maintaining proper humidity levels is essential for the stability and durability of their designs.
