Glad I had so much positive feedback on my zombie thread thanks to all who replied. As I promised I would post the recipies used. I started a new thread to keep things more streamlined but I will link the two threads together to make it easier to find later on. Here is the link to the first zombie thread. http://hauntforum.com/showthread.php?goto=newpost&t=7190
The first recipie is a standard formula used for making prosthetics if you have ever bought "gel fx" this is somthing like that just WAY less expensive.
100 grams sorbitol
100 grams glycerine
20-30 grams gelatine (300 bloom, an industral grade)
water based makeup or powdered makeup for color.
pinch of red rayon flocking
mix a small amount of zinc oxide with some sorbital or glycerine and add this to you mix for opacity about a 1/2-1 gram
wait till all the gelatine apsorbs the liquids before melting, overnight if you have time.
Heat in microwave for 1 1/2-2 mins intervals mixing well inbetween cooking times. Don't allow mixture to boil or foam. If you have to let it cool down some to keep it from bubbling do so. when all the gelatine crystals are melted it's ready to pour. spray a light coat of pam cooking spray or brush a light coat of vasaline or caster oil onto you positive and negative molds. Pour in your gelatine and clamp or stand on your closed mold. depending on your thickness it should be set in 1/2- to a few hours. Demold carefuly leaving it in the negative side of the mold. Try to leave the flashing on the piece this will give you something to hold during the application and keep your edges from rolling under. While still in the mold use 99% alcohol to clean the release off the back of your prosthetic or this wiil keep it from sticking to the skin. Before gluing it down you need to brush a barrier on the backside to keep sweat from disolveing it. Use prosaide or telesis or spirit gum first then a layer on the face where the piece will sit. Press in place working from the center out, use a little witch hazel to disolve your edges and remove the flashing. Lightly powder and color with makeup. This recipie can also be used directly on the skin to buildup burns and scars OBVIOUSLY let it cool down to a safe tempature before using. Here is a picture to see some of this stuff in action, I find it easier to color than foam latex because it's translucent plus you can get a very close color match to your skin type. It is not as durable as foam and does not do well on hot sweaty days so be sure to use it in the right places.
This is the formula for the brush-on zombie skin.
8 cups of water
1300 grams of glycerine
1000 grams of sorbitol
10 packs of surgell (for jam making)
400 grams gelatine
Same mixing and melting instructions as above, but I leave it without color or zinc oxide.
When it's melted and cooled down to a safe tempature, use a brush to carefully brush a layer onto the area you want zombiefied, when it's set paint on some adhesive (prosaide/spirit gum/telesis) anywhere you want your latex to stick, if you want rolled up peeling skin, leave those areas with no glue. Stipple two layers of latex ontop of your gelatine and paint with makeup. Here is the photo again to see an example.
Here is some more links to help understand the process and find the materials needed.
