what do you use to cast face molds
Making a Face up Mold with Algiform
I utilize algiform because it is an easy material to mix, it picks-up neat pare detail, and sets fast (about 5-8 minutes).
If you lot are making a face up mold for the start time, brand sure you have a helping hand, that the model is comfortable and informed of all the steps of the process. Get together all your materials and exercise not begin applying the algiform until anybody and everything is ready.
One time you start, brand speed of application and the condolement of the model the highest priority. The whole procedure should be done in about fifteen-20 minutes.
Make certain the model has a articulate breathing passage. Straws wrapped in cotton wool can be carefully inserted in the nose. I usually cut them in half then I don't hit them accidentally as I apply the molding material. A tube between the lips tin can also be used for animate, only it will distort the mouth. If you are careful you can work around the nose without blocking information technology.
Use warm water to mix the algiform (the paste will be more pleasant for the model)
Apply warm water for the plaster "mother mold" to accelerate the setting time.
Do not trap any hair in the algiform or the plaster (use a thin coat of vaseline for eyebrows). Y'all do not demand to add together vaseline to the eyelashes. If your mold is to cover the caput, you should cover the pilus with a swim cap, and use a heavy coat of vaseline on any hair that is going to be covered by the mold.
Algiform has a very short shelf life. It will dry out and get very brittle inside a day, and then y'all should cascade the cast within a few hours of the completion of the mold. Wrapping the Algiform in a wet towel and inside a ziploc bag will extend its usefulness only not by much.
1 - Make the Flexible mold.
Make sure the model is comfortable, and work as fast as possible to minimize discomfort. Use a sparse coat of vaseline on the middle brows, sideburns, and on the eyelashes. It'south all-time to have one or two assistants during the procedure.
Utilize the Algiform on the entire face and avoid the hair line. A bold cap or a swim cap tin be used to protect the hair form trapping algiform. Few pieces of algirom will come off pilus, but large quantities trapped in hair tin can be a pain to deal with.
Make sure y'all do not encompass the nose (humans do need to breath). If algiform accidentally enters the nose cavity, tell the model to open his/her oral cavity to jiff and to blow hard through the nose to miscarry the algiform.
Make sure to cover the optics and mouth start while the algiform is however fluid. Be careful not to trap air bubbles, especially around the eyes and mouth. The algiform stays workable for about ten minutes if mixed correctly, but once it begins to prepare, it hardens fast.
Terminate by covering every part of the face up (except the olfactory organ!). A consistent layer is all you demand. The algiform wants to skid down the face up when it's however liquid, so exist sure to keep working it upwards until information technology hardens.
Expect a few minutes to make certain the mold begins to gear up
ii - Make a "Mother Mold".
Apply plaster bandages with plaster on top of the algiform. The hardened plaster will allow the flexible mold to keep its grade. If you lot don't have medical gauzes yous can utilise thin strips of cheesecloth dipped in wet plaster.
Wait until the plaster begins to set up. It will begin to feel warm and as soon as it begins to absurd down, you tin can begin taking it off the confront. The plaster is hard only still not set, so be careful not to distort it or interruption it.
Pull the flexible mold and the mother mold carefully. (Make sure no hair has been trapped in the material). It might help to pull the plaster jacket off first and so work the algiform mold after, but I similar to pull them together to minimize any chance of information technology tearing or distorting.
The model (Vanessa) and the mold.
You volition demand to begin the casting process apace afterward you pull the mold from the face. Algiform has a limited life and information technology will begin shrinking and condign brittle very quickly. If you can't brainstorm the casting procedure immediately, submerge the algiform mold in a bucket of water. I found that the mold will yet be usable the next day.
3 - Make the Cast.
Prepare for the cast. Employ some algiform to plug the nose holes and a plaster bandage to reinforce information technology. To make a cast, you demand the mold, a spatula or tongue suppressors, a container and...
...some medical bandages cut into little strips.
Pour water into container
Pour plaster in container until water is saturated with plaster particles. (the dry-bang-up surface is a clue that the mixture is ready to mix). I like to apply the first glaze with a "splash" technique, simply you lot may use a castor to piece of work the plaster on the mold surface. Exist careful not to trap any bubbling
The final plaster of paris bandage shows all the detail of the face up and preserves the fine peel texture. You can employ dental tools (inquire your dentist if he tin give you lot some old ones) to clean all the imperfections around the nose and to "shave" whatsoever blemishes.
You tin employ a diluted glaze of shellac (dilute with denatured alcohol) on the plaster to seal the surface, or you lot may employ other finishes similar spray paint, or plaster rubbings, or anything else - be creative.
Remember, this is simply a face mold. It's not art until you make it art.
