Washable Blood

Make Washable Blood

There are many types of ‘blood and wound’ effects that can be made up for film.
It depends on what type of wounding or ‘bleeding’ is needed for the scene i.e. cut throat – gushing blood, torn wounded flesh – coagulating blood etc. to what you need to make.
If you are new to this I strongly recommend that you study up on the different visual stages of bleeding, wounds and bruising before getting into making these effects.
Washable Blood
Washable blood is handy to have if your actors have to wear the same costume usually a few times for scenes before the actual ‘bloody scene’. It saves on the wardrobe/costume budget.
If it is for a particularly gory blood spraying scene, you are likely to have to make gallons of the stuff, so be prepared.
The main ingredients are liquid sorbolene, food colouring and concentrated dish detergent.
To make a gallon you will need:
2 x 28 oz. bottles of clear or orange ultra-concentrated dish detergent
One small bottle of ultra-concentrated Dawn dish detergent (blue).
2 x 28 oz. bottles of clear liquid sorbolene. (Can be purchased in bulk food stores and Chemists)
3 x jars of dark red cake decorating colouring (oil based)
some black and blue cake decorating colouring (oil based)
OR
1 x 16 oz. bottle of washable red acrylic/poster paint
Blue washable acrylic/poster paint
Black washable acrylic/poster paint
Tools:
Large pot or mixing bowl
Gallon-sized jug or pitcher
Bamboo skewer and Spoon
Strainer or cheesecloth
Funnel
Stove top or Microwave oven
Pour all of the detergent and liquid sorbolene into a large bowl or pot.
Add 8 oz. of the blue Dawn. Mix well. The blue detergent helps to tone down any orange colour.
There is some experimentation to tweak the colour you want.
Using the bamboo skewer, dig out the *red food colouring and stir until the colour is evenly distributed. Repeat this action until you have the correct depth of colour. Make sure this is well-mixed, as the next step is to adjust the colour to look more like real blood. Using your skewer, adjust by using smaller amounts of *blue and *black food colouring until you are satisfied with the result.
Once you are satisfied with your mix, slowly heat on stove or in a microwave to just under bubbling and if need be, pour through cheesecloth if you have any lumps.

Using the funnel, pour back into the bottles or bought ones and seal. You should jot down the ratios of food colouring just in case you need to make more.
It’s wise to write on the quart/litre bottles the date and give it a batch number so you don’t mix up your batches and can look up the ratios.
