i just needed to know the best ones for oozing and the best for dried blood.
As is often the case, the “best” is what you like. All blood
recipes are essentially the same; a clear syrup (here in the
states Kayro is the most used brand) for thickness, food color for
color (red and a touch of blue) and then something to make it
slightly more opaque. I use black coffee. Milk can be used. What
you end up as calling “best” will depend on your personal needs.
The very “best” blood is the blood you make by experimenting.
Dried blood has always been an issue. Real dried blood turns
brown. Food coloring does not decay like blood so will remain red
forever. I tend to buy pre made “dried” blood. But with some
experimenting, you should be able to get the right color. Rather
than a corn syrup, I use liquid latex for dried blood. Or even
paint. A water based paint like Tempera is excellent.
My issue with real intestines isn’t the decay factor; when full
you know what they are full of. Crap. And that stinks no matter
how cold the weather is. When you buy cleaned intestines you gotta
fill them with something. So my method is to just make them with
cotton and liquid latex.
So where do you buy liquid latex? Use Google. Type in “liquid
latex” and even your city for locations. There are makeup places
all over America that sell it - I assume Canada has a few places.
