- •
Acid atmospheres may cause damage to all types of stones.
- •
In calcitic stones, the effect of acid atmospheres is related to porosity.
- •
Intensity of colour change depends mainly on the inherent stone colour.
- •
Artificial finish influences the acid atmosphere’s attack.
- •
HNO3/H2SO3 ratio controls whether nitrogen compounds react with the stone or acts only as a catalyser.
