Hair is prepared using water-based hair gel.
Eyebrows are also prepared with water-based hair gel.
Model is ready to be molded.
Alja-Safe® alginate and water measured out. Slightly less water than alginate will make Alja-Safe® thicker in consistency.
Water is poured into the mixing container first.
Alja-Safe® alginate is added into the water.
For best results, mix components while adding powder into water.
Using a Squirrel mixer attached to a power drill helps to blend a large batch of alginate consistently and fast.
When Alja-Safe® alginate is thoroughly mixed, it can be applied to the model.
Alginate is applied from the top down.
Alja-Safe® remains workable for about 8 minutes giving you time to work into all detail areas.
More alginate is added until mold sufficiently thick (at least 1/2" / 1.27 cm).
Face covered with Alja-Safe® alginate. At this point, no more alginate is needed. Note the holes in the nose - so the model can breath.
Salt is added in to warm tap water (80° F / 27° C) to accelerate dry time of plaster bandage.
Plaster bandages are dipped in water to activate.
Excess water is squeezed out of the plaster bandages.
The plaster bandages are then applied directly onto the alginate.
The edge of the support shell is created first around the perimeter of the alginate mold.
Plaster bandages will 'meld' into itself.
The entire alginate surface area needs to be covered by the plaster bandages to ensure proper support.
The exterior of the plaster support shell is smoothed out while the bandages are still moist.

Plaster bandage support shell completed.
Begin the demolding process with the mold leaning forward.
Running a finger on the inside perimeter of the alginate mold will help to loosen it from the face.
The alginate will separate from the face very easily.
The alginate is supported by the plaster shell to prevent any tears from occuring.
Before the mold can be cast into, the breathing holes in the nose must be sealed off. A small amount of Alja-Safe® is mixed up and applied.
Attention is paid to filling in the nose holes without creating any new detail in the mold.
A tongue depressor stick is used to smooth out the alginate.
The finished Alja-Safe® alginate mold with plaster bandage support shell.
duoMatrix® NEO polymer-modified gypsum measured 2 Parts A : 1 Part B by Volume will be used to make a casting from the mold.
The duoMatrix® NEO liquid is poured into the mixing container first, followed by the powder.
A Squirrel Mixer attached to a power drill is used to mix the batch of duoMatrix® NEO thoroughly and fast.
The duoMatrix® NEO is cast into the mold after being thoroughly mixed.
After 60 minutes, the duoMatrix® NEO casting is ready to be demolded. The first step in this demolding is to remove the support shell first.
The Alja-Safe® alginate mold is then carefully removed from the casting.
