An air dry clay that dries hard like polymer clay, can be coloured or painted! Use it to make amazing things like jewellery, ring plates, gift tags and more!
Cold Porcelain is an air dry clay that is easily made at home using ingredients you probably already have in your house. In this post I will share my recipe, some tips when using cold porcelain and the pros and cons of cold porcelain.
Cold Porcelain Recipe
Lets get started with making the cold porcelain. You are going to need the following ingredients and tools -
* 1 cup of cornflour
* 1 cup of PVA glue (any PVA glue is fine)
* 2 tablespoons of baby oil
* 2 tablespoons of vinegar or lemon juice
* Sorbolene cream ( use a cream that doesn't have any added ingredients like Aloe Vera, Shea Butter etc. Glycerine is fine) This is used to stop it sticking to your hands and the mat while kneading.
* Pyrex dish (or other heat resistant, microwave safe glass bowl)
* Plastic knife
* Measuring cup
* Disposable gloves
* A work mat (craft mat or plastic chopping mat)
* Ziplock bag
* Airtight container
Step One - Combine Ingredients
Place cornflour, glue, vinegar and baby oil in the pyrex dish. Using your plastic knife slowly combine the flour and liquids together ensuring you don't splash the flour everywhere.
Stir until almost all the lumps are removed, get the mixture as smooth as you can. Ensure you scrap all of the flour from the bottom of the dish.
Step Two - Cooking
You will be working in 30 second intervals.
Place the pyrex dish in the microwave and set the timer for 30 seconds.
After 30 seconds remove the dish and stir the mixture. Your aim is to not remove the lumps forming, but to scrap the mixture from the side and bottom and to mix the in the "skin" that forms on the top.
Place the dish back into the microwave and repeat.
It will take between 3-4 30 second cycles to complete depending on your microwave. Your mixture is ready when the mixture has come together when you mix it and it is no long liquid. It will still be very sticky, but it should not be a running liquid anymore.
Step Two - Kneading The Dough
Now you need to put your gloves on. Squirt your mat with a pump or two of sorbolene cream and lightly coat your gloves.
Remove the mixture from the pyrex dish and start kneading it in your hands.
***WARNING at this stage it is hot, so please be careful!!***
It will be very sticky for a few minutes as it cools down. If it is too sticky you can add a small amount of sorbolene cream to you hands again to help.
Once your dough has cooled enough so it is not sticky anymore, remove your gloves and knead the dough on the board. As if you were kneading bread. Smooth out any lumps and remove any overcooked hard pieces you can feel.
Once the dough is cooled and kneaded roll it into a log shape and cover it in a thin layer of sorbolene cream. This will stop it sticking to the wrap.
Wrap the dough in clingwrap ensuring their is no air in it. Place it inside a ziplock bag and remove as much air as you can then place into an airtight container and leave for 24 hours either on the bench or in the fridge. Remove it from the fridge an hour before you plan to use it and store in a cool dry place.
Colouring Cold Porcelain
Cold porcelain in it's basic state will dry a murky white transparent. It will look as if there is an off white piece of ceramic with a merky transparent coating on it. To make the Cold Porcelain white or any other colour you need to colour the dough or you can paint it after it has dried.
What can you use to colour cold porcelain?
* Acrylic paint - is the preferred method, you can use any colour you like and they are easy to find in discount stores or art shops.
* Gel or Powdered Food Colours - this method is just as easy as acrylic paint and I find it gives you a little more control over the depth of colour.
To colour cold porcelain, remove the amount of dough you need (it is always best to colour it as you need it, rather than keeping batches of different colours, this will keep it fresh and stop it drying out). Place a drop of acrylic paint or food colouring onto the dough and massage it in until the colour is completely blended, if you require more colour just repeat the step.
Adding colour can make the dough a little sticky again, so place a little cornflour on your work service to take away the stickiness.
It is best not to use liquid food colouring from the supermarket as this can affect the drying process.
Pros and Cons of Cold Porcelain
Cold porcelain is a great clay to work with, however there are some pros and cons to it .....
Air Dried - Cold porcelain is an air dried clay, meaning you don't need to bake it or use a special kiln. It will dry in the open air.
Soft - it is a really soft clay so it moulds into shapes very easily and is easy to handle.
Cheap - It is a very cheap clay! It costs less than $5 to make a 300g batch compared to $7 for a 56g piece of polymer clay.
Can Be Coloured - Unlike other clays you can make cold porcelain any colour you like very easily. You start with a base mixture and colour portions as you need it.
Air Dried - Yes this is a con too! Because it is air dried it can take up to 3 days to dry completely. This means if you are impatient like me you need to wait to paint and seal your gorgeous creations!
Shrinkage - Porcelain clay shrinks as it dries and can shrink as much as 30%. So while it is great for making handprints etc it will shrink as it dries. When making items it is best to make them larger then you want them to be to allow for shrinkage.
Cracks - Because it is air dried it has a higher chance of cracking as it shrinks. It is suggested that items be no thinner than 4mm to help prevent cracks and also work quickly ensuring your dough is still soft when you have finished moulding it into shape. If you take too long and it begins to dry it will be more likely to crack.
Cold porcelain is a very versatile clay that can be used to make just about anything you would make with other clays. It is cheap and easy to make and super fun to use! The only limit is of course your imagination!!
