Introduction: Homemade (Oil-based) Modelling Clay
I enjoy stop motion animation, so was inspired to attempt making my own plasticine.
It's not exactly cheaper than buying the factory made plasticine, but its fun for a rainy afternoon so the kids can stay entertained.
My recipe is experimental, so I'll attempt to keep improving it. These measurements will give a soft textured plasticine modelling clay.
Step 1: Collect Your Ingredients
As this recipe was rather experimental - I kept adding ingredients until the texture of the plasticine seemed malleable and firm enough to sculpt.
Step 2: Melt Ingredients
Ingredients
1 A4 sheet 100% beeswax (100g)
6 teaspoons mineral oil (baby oil)
3 tablespoons petroleum jelly (vaseline)
2 tablespoons coconut oil / linseed oil
1/2 cup limestone powder
Place some water in the larger pot. Bring to boil.
Place the smaller pot inside.
Break beeswax into smaller pieces. Melt at medium heat.
Step 3: Add Limestone Powder and Oils
Stir in 3/4 cup of limestone powder. Stir until all lumps are smoothed.
Add baby oil, coconut oil / linseed oil and petroleum jelly last 30 seconds of stirring well before turning off heat.
Quickly pour onto trays / plates lined with aluminum foil.
It will harden quickly - in around 10 minutes. Check the texture by rolling with your hands.
If the texture is too firm place modelling clay into double pots again, reheat on low and add more lime powder, petroleum jelly and mineral oil. Cool again.
TROUBLESHOOTING Texture Problems
Too crumbly - Increase the amount of wax and oils to increase stickiness and soften texture of overall mix. The mixture should become more malleable and thinly rolled sections will no longer fall to pieces.
Too firm - Add more oils and limestone powder. It should become more sticky. If the ratio of beeswax is larger compared to the other ingredients, the modelling clay will be quite firm. This is perfect for finer sculpting.
PS. Its possible to experiment with turpentine and linseed oil for softening or thickening your mixture - but away from the stove for saftey.

Step 4: Colour You Plasticine
Add tumeric for bright yellow.
In the pictures above I added 1 tablespoon of dried colour pigments to my mix
You could experiment with oil paints for colouring.
Store in an air tight container.

It's interesting to note that oil paints contain the same ingredients in this experimental plasticine recipe with the exception of whiting or lime powder (calcium carbonate).
Step 5: What You Can Do With Plasticine?
Check out this instructable for modelling tips which will help greatly with creativity.

Animation, casting, stop-motion, jewelry, plasticine paint-by-numbers gifts - possibilities with plasticine are endless!
********************************
Here's a quick tip on warming a cold lump of your modelling clay easily.
1. Tear clay into small sections. Wrap in plastic wrap.
2. Place boiling water inside hot water bottle. Cover with plastic bag.
3. Place small clay pieces around plastic bag. Cover again with another plastic bag and wrap tightly with towel or other material.
4. The clay lumps will soften within 5 minutes.

Hi
For the powder can be used also
1.clay powder
2.pure caoline
Thanks

Hydrated and slaked lime are very caustic and dangerous. Calcium carbonate is much safer -- that is chalk, just like kids use on sidewalks.

can it dry?
Reply 5 years ago
No, it won't ever dry. If you try to dry it with heat it will just melt Because it is an oil based clay, it will stay flexible and never get really hard.

Back in art school, I seem to remember we made Plasticine (oil based clay) out of dry clay (filched from ceramics dept) mixed with melted paraffin and motor oil. I was never involved in the making, so I don't know the recipe, but I vaguely remember they used a giant bakery type mixer to blend it all up. It felt a little grainier than store bought, but it worked just fine.

Thanks! Very useful info. how did your hands react to the motor oil? is that petrol by any chance?
Reply 5 years ago
Not petrol, but the oil used for lubricating the engine. Here is a recipe I found online:

Hi,We want to know why the color come while we play with clay?
Why kind of pigment should we use and how to get it ?
We appreciate your reply.
Thanks,

Hello, I have some doubts as to the proportions.
First ask apologize bad english, I'm Brazilian.
I used 300g of beeswax, different this, to which I came in a dark bar.
3x each measure used oils, and also lime. Oh, and I opted for flaxseed oil instead of coconut.
Following this recipe, got a soft dough and was brittle. She "crumbled/brittle,", so I added more wax and oils.. Result was no longer brittle mass, until it was found in the sweet spot, but when you start modeling, she was too clingy. Stuck on the fingers, and the work tools.
melting again what ingredients should I add?
I really need your help, anything: Marcelo.nantes@msn.com
Surely its revenue and encouragement is what I need as amateur sculptors,
Thank you!

FYI calcium carbonate is the active ingredient in tums antacid tablets and in most calcium supplements. I take it almost nightly for acid reflux. You can buy a bottle of 60 tablets with 500 mg of calcium carbonate per tablet of the generic tums at the dollar store for a buck. Many "clay" recipes I've found online have said you can simply crush up supplements into a fine powder to use in these preparations. It is also used in many other pills as a filler and is a common food additive so I'm pretty sure you've ingested it at some point.
If you use food grade mineral oil and the coconut oil I don't see why you couldn't simply wash the pans afterward and still use them for cooking in. There is also food grade paraffin wax that is in gum, candy, etc. and it is the wax they use to wax dip many cheeses. While it's unable to be digested it is perfectly safe to consume. The fumes that are toxic are from burning it or melting it at very high temperatures, as in the hundreds of lit candles you've been around in your life might give you cancer someday. Remember those candy wax lips, wax soda bottles, wax teeth etc.? They are paraffin, as are crayons. Many candles still contain paraffin.
So all in all this seems pretty safe other than consuming high quantities of calcium carbonate can cause kidney damage and don't burn your paraffin. Don't eat it, (it would probably taste horrible anyway) and don't burn it, but otherwise you should be good to go.

Where can you get the beeswax and limestone powder?
Reply 10 years ago on Introduction
Limestone powder is also called hydrated lime. it is a filler for the plasticine. i went to a hardware store to buy the limestome power
the other type of calcium carbonate is mixed with additives to make concrete or quicklime. i wouldn't use this, but used hydrated lime with stays malleable.
i found beeswax in the yellow pages and found a candle specialty shop which sold it so you could make your own beeswax candles.
it cost $20 for 10 sheets. the other place i found it on ebay for much less. as i said, its not necessarily cheaper to make it yourself, i made it for the fun of figuring out a working recipe. all the best!

I created an account just to say DO NOT USE HYDRATED LIME in place of calcium carbonate! Perhaps the oil prevents much caustic lime from dissolving and attacking your skin, but people who are working with cement without gloves get alkali burns from that stuff. Someone with sweatier hands than OP will burn themselves doing this. if you want an inert mineral filler, use an INERT mineral filler.
You will be able to buy ball clay, feldspar, talc (magnesium carbonate) or calcium carbonate at a pottery store. It will be just as cheap or cheaper than caustic hydrated lime, and you can buy smaller quantities of it.

Thank you for this easy recipe, but I need to know if this clay is air dry or not. Thanks
10 years ago on Introduction
If you mean air dry clay, I'm sorry to say this is a a heat sensitive modelling clay, melts very quickly in a double boiler. It hardens best in cold weather.
