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.

What does heat limestone with clay produce?
Heating limestone with clay produces cement, which is a key component in the production of concrete. This process is known as calcination, where limestone and clay ingredients are mixed and heated to high temperatures to form a substance called clinker.
What is made by grinding calcined limestone and clay?
cement
What sedimentary rock is a loose earthy deposite of limestone and clay?
The sedimentary rock that corresponds to a loose, earthy deposit of limestone and clay is called marl. Marl forms from the combination of these materials as they settle and are compressed over time.
Is anhydrite harder than limestone?
Yes, anhydrite is generally harder than limestone. Anhydrite, which is composed primarily of calcium sulfate, typically has a hardness of around 3 to 3.5 on the Mohs scale, while limestone, primarily composed of calcium carbonate, has a hardness of about 3 to 4. However, the hardness can vary depending on the specific type of limestone and its mineral content. Overall, anhydrite is considered to be more resistant to abrasion compared to limestone.
Does limestone and clay make cement?
Yes, limestone and clay are the two main ingredients used to make cement. They are crushed, mixed in precise proportions, and then heated in a rotary kiln to produce cement clinker, which is then ground into a fine powder and mixed with gypsum to make cement.
How does clay turn into limestone?
Clay can turn into limestone through a process called diagenesis, where the clay particles are subjected to compaction and cementation, forming a new rock material. Over time, the minerals in the clay are altered and precipitate out to form calcium carbonate, which is the primary mineral in limestone.
Are cows better on limestone or clay?
Clay, it is better on their hooves.
What can be heated with clay to make cement?
calcium carbonate (limestone)
Is chalk harder than limestone?
No, limestone is harder than chalk. Limestone is a sedimentary rock composed mainly of calcite, whereas chalk is a soft, porous sedimentary rock composed mainly of calcium carbonate.
How do you make cement from limestone?
you make it by mixing limestone powder and clay in a kiln
Was the sphinx made of clay?
No, The Sphinx was made of limestone blocks
What does heat limestone with clay produce?
Heating limestone with clay produces cement, which is a key component in the production of concrete. This process is known as calcination, where limestone and clay ingredients are mixed and heated to high temperatures to form a substance called clinker.
Is Kimmeridge clay a hard or soft rock?
Kimmeridge Clay is a soft rock, composed mainly of clay minerals such as illite and kaolinite. It is typically easily eroded and can have low strength compared to harder rocks like sandstone or limestone.
Is granite harder than limestone?
Yes
What is made by grinding calcined limestone and clay?
cement
What fuel heats limestone and clay?
The fuel typically used to heat limestone and clay in cement production is coal, natural gas, or petroleum coke. These fuels provide high temperatures needed to convert the raw materials into cement through the process of calcination.
What are clay pigeons made of?
pitch and pulverized limestone rock.
