SOFT CLAY SLIME RECIPE THAT’S SMOOTH AS BUTTER!
What’s so special about soft clay slime? Here’s a few things we have found that are really cool about this slime. First, it stays nice and stretchy longer. Second, it’s a bit moldable. Third, it’s smooth, rich, and silky feeling.
Soft clay slime inly requires one extra ingredient and uses any one of our three basic slime recipes. I will tell you which one is my favorite below because we experimented with all three of them to find the best one!

PREPARING YOUR SOFT CLAY SLIME RECIPE
Now that you have your basic slime recipe made, it’s time to mix in the clay! There are several types of clay out there to use. We have chosen to use the Crayola Model Magic clay as it’s readily available around us. However we have found another option you can see here, and it comes in a variety of colors.
CLAY NOTE: The denser the clay, like this clay, the less you will want to use. A less dense clay will require you to use more. Feel free to experiment with the consistency you like the most.
We have experimented with two different amounts of the Crayola Model Magic clay and found that mixing 1/3 of a standard 4 ounce packaged worked nicely. The first time we used 1/2 a package. We ended up with a thicker slime, less stretchy.
MIXING YOUR SOFT CLAY SLIME RECIPE
Get your muscles ready for this one! This will take a few minutes to mix, so don’t get discouraged that it doesn’t happen immediately.
In the beginning you might even think that it won’t work, but just keep kneading your slime, and it will come together for you!
We chose to start with a yellow base and add a reddish colored clay to it. We have also mixed blue and green and pink and orange! There are so many possibilities including black and white clay!
Start by softening up your clay. Next, flatten it out, and put on top of your slime. Start folding and mixing and kneading and squishing. Remember it will come together and make one smooth color like you see in the last few photos.
You did it! Your clay slime recipe is now ready to play with. We love making handprints in ours. Soft clay slime is so squishy and relaxing to play with too.
STORING YOUR SLIME
Slime lasts quite awhile! I get a lot of questions regarding how I store my slime. We use reusable containers in either plastic or glass. Make sure to keep your slime clean and it will last for several weeks. I love the deli style containers in my recommended slime supplies list here.
THE SCIENCE BEHIND THE CLAY SLIME RECIPE
What’s the science behind the slime? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl-acetate) glue and forms this cool stretchy substance. This is called cross linking!
The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until…
When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime!
Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms the tangled molecule strands are much like the clump of spaghetti!
Is slime a liquid or solid? We call it a Non-newtonian fluid because it’s a little bit of both! Adding the soft clay definitely changed the initial viscosity of the slime didn’t it?
WE HOPE YOU ENJOY MAKING THIS CLAY SLIME RECIPE!
