Yes, a clay wall can be treated with bonding plaster. Bonding plaster is designed to adhere to a variety of surfaces, including clay, and can be used to create a smooth and even finish on the wall. However, it is important to properly prepare the clay wall before applying the bonding plaster to ensure good adhesion. This may involve cleaning the surface, applying a primer, or roughening the clay to create a better bond. Additionally, it is important to follow the manufacturer's instructions for applying the bonding plaster to achieve the best results. **

It is not recommended to mix expanded clay and clay plant granules together. Expanded clay is a lightweight, porous material used for aeration and drainage in soil, while clay plant granules are typically used for moisture retention and as a soil amendment. Mixing these two types of materials together can result in an inconsistent soil structure and may not provide the intended benefits for plant growth. It's best to use each material separately for their specific purposes in soil composition. **

Clay is not inherently waterproof, as it is a porous material that can absorb water. However, clay can be made waterproof by firing it in a kiln at high temperatures, which causes the clay particles to fuse together and create a waterproof barrier. Additionally, clay objects can be glazed to make them waterproof by adding a layer of glass-like material that seals the surface. **

Yes, there is a purely visual difference between clay and modeling clay. Clay is a natural material that is typically found in earthy tones such as brown, red, or gray, and has a more rough and natural texture. Modeling clay, on the other hand, is a synthetic material that comes in a variety of bright and vibrant colors, and has a smoother and more pliable texture. Additionally, modeling clay is often softer and easier to mold than traditional clay. **

Modeling clay is not inherently waterproof, as it is typically made from water-based materials such as clay, water, and other additives. However, some modeling clays may become water-resistant or waterproof after they have been baked or cured. It is important to check the specific instructions and properties of the modeling clay you are using to determine its waterproof capabilities. If waterproofing is necessary, a sealant or waterproofing spray can be applied to the finished clay project. **

Dogs should not eat clay as it can be harmful to their digestive system. Ingesting clay can lead to gastrointestinal blockages or other health issues. It is important to keep potentially harmful substances away from pets and provide them with a balanced diet that meets their nutritional needs. If you suspect your dog has ingested clay or any other non-food item, it is best to consult with a veterinarian for guidance. **
