On the other hand, solid masonry can be more versatile in terms of material options and cost-effective, but may not have the same visual impact as solid stone masonry. **

Saltpeter, also known as potassium nitrate, is a crystalline compound that has been historically used in masonry as a key ingredient in mortar. It helps to improve the setting time and strength of mortar, making it an important component in traditional building practices. Saltpeter can also act as a water repellent, helping to protect masonry structures from water damage and deterioration. **
