How to make fake or stage blood by Lars from Makeup-FX - Sweden

You will be surprised when I tell you how simple it is to make a very realistic stage and film blood.

Recipe:
98% Sorbitol (liquid) - Can use our powdered as a starting point or go straight for the liquid.
2% Red food colour for best results use either one of these powders, don't use liquid food colour it will stain everything badly:
Amaranth Red Colour Powder C309 (E123) - 100g available from online store
Ponceau 4R Red Powder - Colour 124 (E124) - 100g available from online store

Preservative:
0.5 % Sodium benzoate - 1Kg bag available from online store
I recommend this if you want to store it for more than 2 weeks.

Method:
Mix well. All Finished if you have time let it stand for a few days to make sure that all the powder is dissolved.

Gel blood
This is also very simple. Just take the blood you just made and mix it with a thickening agent until it gets as thick as you want it. My favourite thickener is Cabosil which is a fumed silica. It is also known under the name Aerosil.

You can find this in most boat making shops. It is used for making polyester and epoxy thick for making a gel coat for the first layer of a boat. Go and check in your local boat shop and they will probably be able to help you. I use Cabosil for a lot of things, it thickens everything expect water.
