TECHNICAL FEATURES
A chemical agent used in restoration for the effective removal of deposits, salts, and oxides on calcareous surfaces and resistant artifacts, with rapid release of ammonia and carbon dioxide in a strongly alkaline environment.
Composition:
- Neutral ammonium salt (ammonium carbonate)
- Chemical formula (NH₄)₂CO₃
- High solubility in water
- Active in alkaline environment (pH 10–11)
- Compatible with delivery gels (e.g., agar, carboxymethyl cellulose)
Appearance:
- White or granular crystalline powder
- Soluble in water (clear solution)
- Strong ammonia odor
- pH in solution: 10–11
Main uses:
- Selective removal of stubborn deposits, insoluble salts, and metal oxides on calcareous materials and hard surfaces
- Cleaning of sculptures, architectural surfaces, and metallic artifacts
- Application in gel or poultice for localized and controlled treatments
- Suitable for interventions requiring alkaline pH for treatment efficacy
- Controlled alternative to aggressive chemical methods in conservative restoration
