All About Clay Essential Oil Diffusers

What are clay diffusers? 

While designs and shapes vary widely, most clay diffusers can be split up into the two categories: ultrasonic and diffuser disks.

Ultrasonic diffusers vaporize water and essential oils together, continuously releasing a mist of both. Some have external, design elements made of clay, but don't use the material for diffusing in any way.  

Diffuser disks are small disks or pendants made of permeable clay like terracotta: a red-brown clay that's naturally perfect for diffusing oils. 

 

How do Clay Diffusers Work?

When permeable clay like terracotta is fired in a kiln, water evaporates from the wet clay, leaving behind tiny little pockets (pores), like in a sponge. 

Since terracotta can easily absorb, store, and release water, it tends to have more of these little pockets than most other clays. 

If essential oils are used on diffuser disks (like our Terracotta Diffuser Disks), the oil collects in these empty little pockets.

As time passes, the oil that was pooled in the clay’s pockets evaporates, or is slowly released into the airwhich then releases the essential oil’s aroma. And while Terracotta isn't the only clay that can do this, it's definitely the best for diffusing oils. 

  

What Makes Clay Diffusers Different from Ultrasonic Diffusers? 

The short answer: ultrasonic diffusers use electricity 

While there are definitely energy-efficient ultrasonic diffusers, clay diffusers are a tough act to follow. 

After all, the only mechanism that drives diffusion is the clay itself. This simple difference makes terracotta diffusers the most sustainable diffuser option out there.  

 


Are clay diffusers eco-friendly? 

Yes! The materials are naturally occurring and abundant

terracotta clay requires a lower kiln temperature to bake than most other clays.

While most clay diffusers have a fairly energy-efficient manufacturing process,  terracotta disks have  carbon footprint. 

Basically, terracotta diffuser disks are made with 100% biodegradable materials and use a fraction of the energy used to create ultrasonic diffusers. 

 

 

What is the Best Essential Oil Diffuser?

While it's pretty clear why we love clay diffusers, sustainability isn’t everything for everyone. It's certainly not the only thing to consider when choosing the best essential oil diffuser for you.

The zero-waste possibility of a terracotta diffuser disk may be appealing to some people (Ten Leaves diffuser disks come in 100% recyclable paper packaging).

But honestly, ultrasonic diffusers are much stronger than terracotta diffusers.

While this makes clay diffusers great for places like the car, shared spaces or your bedside table, they often aren’t the most effective choice for larger rooms.

How Do We Make Clay Diffusers?

Here at Ten Leaves, each handmade clay pendant and diffuser disk is carefully air-dried and then kiln-fired over the course of several weeks. 

Trust us, we struggled for a long time and tested countless methods to make our diffusers. So we hope you understand if we can't give away all our trade secrets. 

And while we're not fans of vanity, we are proud of the hard work, time and artistry that goes into making our terracotta clay diffusers. 

We'd love for you to try one of our clay diffuser disks or clay diffuser pendants and see the results yourself! Shop our full collection of diffusers here
