Step 5: Coloring Oogoo

Picture of Coloring Oogoo
I was pleasantly surprised to discover that all it takes to create vibrant colors in Oogoo is very small amounts of linseed based oil paints. Apparently the pigments in oil paints are very fine and dense so a little goes a long way.

About the equivalent of 5 or 6 drops of oil paint per teaspoon of silicone will result in solid colors. I mix the color well with the silicone before adding the corn starch.

While you can leave it white, it is a good idea to add some color to make it easy to see if you have a well mixed batch. Adding color does not appear to significantly effect the hardness or flexibility of the final result.

Why cornflour and not regular flour?

nicko01 year ago
does the cornstarch inside the cured oogoo absorb moisture?

and could there be an issue with corn starch being food for microorganisms.

ideas on 0 food value/ not gonna grow anything moisture carrying substitute?

and or one that becomes non absorbent once its in the oogoo

I read that the person who patented Sugru started with a mixture of silicone and sawdust.

Does anyone know if the Aussie version of corn starch is corn flour?
Yes, corn starch is corn flour. I heard on YouTube that baking powder (not baking soda!) can also be used. I'd stick with the corn starch, which is cheaper than baking powder anyway..
This is confusing and i googled it, , it is probably wheat starch

See http:/ /w w w.holve.com/brad/tips/cornflour.html

I would not stick this in my ear though as others suggest to make ear buds.

Also, could you use colour pigment in the powdered form?

HI Mikey,
You're great that's a super post and idea. Do you have used it to make earbuds actually? Excuse-me if I missed something...I did not see any earbuds yet.
Keep on the good work :)
Just had an idea - you could probably make it glow in the dark by adding strontium aluminate powder. You can buy it on eBay in different colours, it's not very expensive.

would food coloring work?

has anyone tried latex acrylic paint. It is water based so wouldn't mixing it in reduce the need for the starch?

I posted a comment on step 13 about using water based acrylic craft paint. That seemed to work just fine. I initially got the mixture a bit to starchy and had to add a little more silicone, so you are probably right. I'll have to experiment a little more to know if there is a downside to acrylic in the mix.

I would be interested to know if that worked too. Skip a step.

Thank you for the great info. I was wondering, I want to make an orange color with linseed based oil paint to hand form a nose to put on a pumpkin. I noticed in some of the photos the color looks darker in the undried version and lighter in the dry version. Do you think I should make the color very strong or dark so that when it dries it won't tern out too light of a color? Also, do you know if it will adhere well to a pumpkin?
