Why Do You Put Sand In The Bottom Of A Chiminea?

You may be asking why I need sand of all things in the bottom of a chiminea.

Well to answer that question, sand is placed in the bottom of a chiminea to help insulate it and protect the bottom of the unit from the heat of the fire, the sand acts as a layer of insulation between the fire and the bottom of the chiminea, preventing direct contact with the heat source and reducing the risk of damage.

In addition to providing insulation, the sand also helps to absorb moisture that can sometimes collect in the bottom of a chiminea, sand will also help to prevent the buildup of moisture, which can cause rust in metal and other forms of corrosion over time.

What Kind Of Sand Do You Put In A Chiminea?

The best type of sand to put in the bottom of a chiminea is sand that is labeled as “Sharp sand”, also known as “builders sand“, this is a type of sand that is commonly used in construction and DIY projects, it is a coarse sand that has larger particles and is free of organic matter.

So you can recognize sharp sand, it is often used as a base for paving, patios, and driveways, as it provides good drainage and a stable foundation for construction materials, it is also used to make mortar, which is a mixture of sand, cement, and water that is used to bind building materials together.

The term “sharp” refers to the angular edges of the sand particles, which help to create a stronger and more stable structure, builders’ sand is typically sourced from quarries and is often washed to remove impurities and ensure consistency in size and texture.

So with that said you can see why this type of sand is the proper sand to use in a chiminea

What Kind Of Sand Should I Avoid?

When using sand in a chiminea, try to avoid any sand that contains a high percentage of clay, silt, or other dirty things, these types of sand can hold moisture and may not be able to withstand the high temperatures generated by the fire, which can cause the sand to crack or even explode.

Beach sand, for example, should be avoided, as it often contains a high percentage of salt and other minerals that can react to the heat of the fire and cause the sand to break down and also smell.
no one wants dirt sand in their chiminea anyways.

Instead of using sand that is dirty, it’s recommended to use clean, dry, and coarse sand, like builder’s sand, these types of sand are specifically designed for construction and are free of impurities, which makes them ideal for use in a chiminea.

Something important is to choose the right type of sand because using the wrong type of sand can be dangerous and cause damage by holding moisture and causing cracks or damage to the chiminea.

How Much Sand Do You Need In A Chiminea?

Now the amount of sand in a chiminea that you will need depends on its size, as a general rule of thumb, you should fill the bottom of your chiminea with about 3 inches of sand.

So the best way to determine the amount of sand needed for your chiminea, you can do this by measuring the diameter of the base and multiply it by 1.5, this will give you the approximate amount of sand needed to fill the bottom of the chiminea to a depth of 3 inches.

Try not to overfill the chiminea, this can restrict airflow and make it difficult to build a fire, if you need to add more sand over time, you can add it in small increments you may need to do this if you have cleaned out old ashes, try adding no more than 1 inch of sand at a time.

Adding the right amount of sand to your chiminea can help to protect it from heat and moisture, and prevent any cracks or dings.

What Can I Use Instead Of Sand In Chiminea?

Gravel In A Chiminea

You can put gravel in the bottom of your chiminea, gravel is also a good option for protecting the bottom of the chiminea from the heat, and for aiding in the distribution of heat. the downside to gravel is that most of the ashes will collect in them and really this isn’t a problem because with the ashes they will make a protective layer like sand, the bad part is when you have to clean it out you may need to remove all of the gravel to do so.

Something else is to avoid using any type of gravel or stones that have been treated with chemicals or that contain impurities, and these can release harmful fumes when heated.

Lava Rock In A Chiminea

Can put lava rock in a chiminea? yes, lava rocks are a popular choice for lining the bottom of a chiminea as they help to distribute heat evenly and protect the bottom of the chiminea from the heat of the fire, lava rocks also absorb and retain heat, which can help to keep the area around the chiminea warmer for longer periods of time.

Remember that lava rocks should not be used as the primary heat barrier for a chiminea fire, because they do not make a closed protective barrier between them and the chiminea bottom, lava rocks are best used as a layer on top of sand or gravel, or as decorative accents around the fire.

Stones In A Chiminea

It is not recommended to put stones in a chiminea, chimineas are typically made from clay, cast iron, or other materials that are not designed to withstand the thermal stress of direct contact with stones, placing stones in a chiminea can cause it to crack or even shatter, potentially causing injury or property damage.

Putting stones in a chiminea will probably also negatively affect its performance, the stones can block the airflow and reduce the oxygen supply, which can result in incomplete combustion.
