Most likely, it would be chert.
Chert, a form of quartz, can form as beds or nodules in limestone or dolostone.
The hard sedimentary rock that often forms inside limestone is called chert. Chert is composed of microcrystalline quartz and can be found in nodules or layers within limestone deposits. It forms through the replacement of limestone by silica-rich solutions.

A hard sedimentary rock that forms inside limestone is called chert. It is composed of microcrystalline quartz and often forms nodules or layers within limestone due to the replacement of calcium carbonate by silica-rich fluids.
Yes, limestone is considered a hard rock. It is a sedimentary rock composed mainly of calcium carbonate minerals. While not as hard as igneous rocks like granite, limestone is still durable and commonly used in construction and as a building material.
Limestone is a common sedimentary rock that is widely available around the world. It can be found in abundance in many regions and is often used in construction and landscaping. However, the quality and accessibility of limestone can vary depending on the specific location.
The fine grained white limestone surface sparkled in the sunlight from a great distance, adding to the beauty of the pyramids. I think all fo the limestone was stolen long ago by invading armies, though.
Limestone is a relatively soft sedimentary rock composed mainly of calcium carbonate. It has a hardness of 3 on the Mohs scale, which means it can be easily scratched by harder materials like metal or glass.
Limestone would be potentially harder until the clay is fired. The problem we have here is that "clay" is an ambiguous term. There is no homogenous or standard formula for clay. However, clays can generally be formed and baked to become set and hard. This is called firing. Fired clay tends to be quite hard, and depending on the formula, might be harder than limestone.
Flint can typically be found in rocky areas, such as riverbeds, quarries, and exposed cliffs. It is often associated with sedimentary rocks like limestone and chalk. Look for smooth, hard rocks with a glassy appearance, as these may contain flint.
