Halloween Cauldron: Learn how easy it is to transform a plain plastic Halloween cauldron into an old, worn witches cauldron that looks like old cast iron. It’s easy and the results are incredible!
Every Halloween I pull out my favorite large black cauldron and use it for Halloween decorating or to add candy to for our church’s trunk or treat.
I love the shape and size of my cauldron, but I’m just not crazy about the shiny plastic look it has to it.
This year I decided I would figure out how to add texture and depth to my witch cauldron with paint and two other things I’ll be sharing with you.
I just love the result!
DIY Witches Cauldron
My witches cauldron is much more convincing and looks like it’s lasted through hundreds of years with bubbling toxic potion inside.
This would be perfect to use at a Halloween witch party.

I placed mine over a fake fire prop I create with just a few supplies.

Realistic Halloween Cauldron Supplies
- Large witch cauldron (Mine came from Oriental Trading and came in a set of 3 different sizes. I used the large cauldron and it’s a great size!)
- Flat black spray paint (I used chalkboard paint because it’s the most matte spray paint)
- Brown paint
- Copper paint
- Mod Podge
- Spanish moss
- 2-3 foam brushes
How to Create the Perfect Witches Cauldron
Add some texture
Here’s what our cauldron looks like before- shiny and plastic-y, but with a great large shape and a handle on each side.
To add some grit and years witch use to it, I mixed some sand with flat Mod Podge in a plastic cup.
The result was a gritty, goopy texture that I added all over the surface of my witch cauldron with a cheap foam brush.
Although the mixture looks white now, the Mod Podge dries clear.
This leaves behind the sandy texture on the cauldron.
Add more texture
Now for even more texture!
I used this same technique again, but this time I cut up small pieces of Spanish moss with scissors.
Next I added them to Mod Podge and painted it on to create a thicker texture.
I added them around the top of the cauldron and in random places around the sides.
My goal was to make it look like years of chunky potion pieces that oozed and bubbled over in the pot and got crusty over the years.
I ended up pulling off any pieces that were a little too big that I didn’t cut as well with my scissors, then I let this dry completely before the next step.
Paint the witches cauldron black
Next up was some flat black paint.
I first added a few coats of an ultra matte spray paint and I wasn’t impressed.
My cauldron still looked to shiny for my taste so I had to switch strategies.
I had half a can of chalkboard paint left over from a previous project so I tried adding a coat of that over the top.
It worked perfectly and gave me the total matte look I wanted.
Be sure to use multiple light coats of spray paint instead of one coat with lots of paint.
This helps to get the best look with no paint drips on your cauldron.
Add years of use with paint
Now for the fun part!
I was loving the way my cauldron looked at this point with all of the texture I added, but it was a little too flat.
I knew paint would add some depth to my witch’s cauldron and make it look old and worn.
A dry foam brush was loaded with some brown paint and a little black paint added.
This made it look like rust and acidic potion caused discoloration over the years.
The key to this is using just a little paint at a time.
I would add a small amount of paint to my brush, then blot the brush on some cardboard to take off some of the excess paint.
I used this technique all over the cauldron, but added more towards the top and down the sides to look like witch’s brew bubbled over and dripped down the sides.
Sorry I don’t have a photo for this step. I did this at night since I couldn’t wait until the next day because I was too excited!
The finishing touches
To finish off the cauldron, I added some gold metallic paint to the ring handles on the sides.
Next, I added a little more of the brown and black to take away some of the shine and make it look older.
I also added a tiny bit of copper to my brush to add a little bit of metallic to the cauldron.
I just LOVE how my witches cauldron turned out!
Can you believe the transformation?!
Place cauldron over faux fire
To really take this project over the top, I created an incredible fake fire prop to go under the cauldron.
This faux fire complete with ashes and bones lights up and looks like real fire as it’s getting dark!
You won’t believe how easy it is to make this fire with spray foam, lights, fake bones, and paint.
It looks like the fire has been going for a while with ashes and burnt embers.
It’s the perfect accompaniment to your new cauldron!
Have you started getting ready for Halloween yet? I’m hoping to pull out my Halloween decorations this week. So excited!
