Gelatine is a very cheap material used in food and sweets. It has been used in makeup since the 1920ís. Today allergies are on the increase and the need for a safe product has also increased.
Some of the problems with gelatine have been that it is hard to glue it on skin, the appliances have been too heavy and putting melted gelatine straight onto skin may cause burns.
A lot of these problems are solved if you foam the gelatine first.
The air in the foam makes it possible for glue to dry under a piece, the pieces will be much lighter and you can put it straight on the skin without burning you customer.
Of course some problems remain!
Itís much harder to get the edges to be invisible because itís a living material that keeps moving and they are not as stable as foam rubber.
If you can live with these problems then you should keep on reading.
To be able to foam gelatine you must first mix a gelatine base.
Foam gelatine recipe
Take 100 gram of the gelatine base.
Dissolve 1 teaspoon (5 ml) of Tartaric acid (food stores) in 1 teaspoon (5 ml) sorbitol in a little cup. You should always stay away from using water because it evaporates and makes the pieces less stable. Let the mixture stand for at least a minute.
Melt the gelatine in a big plastic cup (at least 5 dl so it wonít run over the edges later on).
Stir down 1-6 teaspoons (5-30 ml) of white school glue (ex. Elmers in the US) with a plastic spatula or plastic spoon.
The reason why you should only use plastic tools is that cold metal tools inhibit the foaming process.
Now add the tartaric acid mix and stir quickly.
Now add 1 teaspoon (5 ml) Bicarbonate (food stores) and again stir quickly.
Now magic is happening! Let the mix rise for a while without stirring it. 30 seconds usually works fine..
The gelatine is foaming because the mix of tartaric acid and bicarbonate in combination with the heat produces carbondioxid (the same gas as you exhale).
The foam now needs to be refined for about a minute by slowly stirring before you use it in a mould or directly on skin.
Putting it directly on the skin
Foamed gelatine is excellent for making scars or burns on the skin or in the hair.
Most of the time you will not need any glue if you apply it to clean skin. I often clean it with a little bit of alcohol first). Let it dry for a minute or so before applying any makeup (PAX or grease paint) to it
The moulds should be prepared with a small amount of Vaseline first.
The moulds should now cool for at least 30 minutes before you take them apart.
If your moulds are complicated you can heat them to about 50-60 įC before putting the gelatine in. This is done to give you more working time before the gelatine starts to set.
Of course you will have to wait longer before taking them apart if you do this.
When the appliances are out wash off the Vaseline with some 96% alcohol.
The appliances can now be glued on with Pros Aide and the edges melted with Witch hazel. Apply PAX paint over them and finish them of with Ben Nye greasepaint.
The foamed gelatine is reusable a couple of times just by melting it again in the microwave. If the foaming disappears you can add some more bicarbonate and tartaric acid.
Reheating foamed gelatine is very quick and a couple of seconds is often more than enough. Remember that it is still not allowed to let it boil!
If you canít get hold of the vinyl medium you could try to use white school glue or wood glue. They both have the same base as the medium but donít work quite as well making the pieces more rigid and less flexible.
