Formal Lesson Plan and TEKS Information

There are many recipes online for homemade clay. Many of them call for flour as a major ingredient and require the use of a stovetop and pan.  But what if you don’t have any flour or you don’t feel comfortable cooking on a stove?  Here are two solutions:  Microwavable “Cold Porcelain” and microwavable “Victorian Salt Clay”.


Recipe 1: Microwavable “Cold Porcelain”



Mix together 1 cup cornstarch and 1 cup glue in your microwavable bowl.

Mix in 2 Tbs baby oil and 2 Tbs lemon juice (or alternative)


Place the bowl with the mixture into the microwave and heat for 15 seconds.

Remove from the microwave and stir. Clumps should be starting to form. Keep heating for 15 seconds and stirring until the mixture is very clumpy and sticky.


Dump the mixture onto a surface of wax paper or parchment paper. Put lotion on your hands to prevent sticking and begin kneading the mixture as soon as it is cool enough to touch. Continue kneading until it is nice and smooth.


Wrap the clay tightly in plastic wrap and let it “rest” for 24 hours in a cool, dry place.

Recipe 2: Microwavable Victorian Salt Clay



Mix 2 cups salt and 2/3 cup water in the microwavable bowl. Heat in microwave until mixture is HOT, but not boiling.

In a separate bowl, mix 1 cup cornstarch and ½ cup COLD water. This should make a very odd, rubbery mixture.


Bring the hot, salt mixture to your workstation and poor the cold, cornstarch mixture into it.


Stir, Stir, Stir.


If the combined mixture does not make a thick, paste-like consistency, return it to the microwave for 20 seconds and stir some more. Repeat until mixture resembles sticky mashed potatoes.

Dump the mixture onto your wax paper or parchment work surface.


Start kneading the clay while it is still warm (be careful not to burn yourself)


Wrap the clay tightly in plastic wrap for storage.
