Topic Subject : Silicone mold

I usually like to cast a Body part from all sides at once, to create an Object which looks good from all sides. But I have got Problems fitting the mold back into position to close all seams which means a lot of work later on.
I use sippers which works quite good, but I am still looking for better ideas to solve this problem.

What are "sippers"? And, how (& with what) do you make a silicone mold
directly from the model? I'm trying to avoid the alginate step, & apply a skinsafe
silicone to the model's body. Does platinum-based silicone allow this? Please
advise.

Dear Rhett

ArtMolds has developed a new-skin safe silicone called LifeRite which allows
silicone molds directly from the body. Matthew Mungle (Edward Scissor Hands

CSI and many other great effects movies and TV shows) has been using it with
great results. You might want to look into that. Though more expensive that
alginates it allow for duplicates that you can't get from alginates without
secondary molds.

I thought 'sippers' were the bane of all bar tenders who of course prefer
drinkers.

Warmest regards

Ed

I have been using SmoothOn Body Double with great success for some time. It
comes in two set time formulas. It is expensive, but if you make a good mother
mold you can pull lots of pieces from the original mold.

Subject : RE: Silicone mold

Those of you using the skin-safe silicones, I just wondered if you can put
my mind at rest about a few things. I haven't tried them myself...there are
a couple of different ones at least available over here in the UK. But I
heard some negative rumours about them (maybe just one of them...not sure).
I'm not singling out any particular brand cos I honestly can't remember.
What I heard from a couple of different sources was about the effect on the
model's skin - basically causing some sort of yellow staining that looked
like bruise marks on the models. I don't know if this is some chemical in
the silicone reacting with the sweat or PH of the models but having heard it
from two sources (highly respected) it put me off taking the risk. I can
imagine the sort of marks they were talking about because for some reason i
get this with certain brands of latex gloves happening to my skin. bizarre
but true.

I love the idea in theory, but exactly how skin-safe is skin-safe? Are they
tested for use on pregnant women or children for example? And if not safe
for them then what are the harmful things the manufacturers won't take the
risks with (Ed, I am sure you can answer this easily for me).

Also, I presume with the brushing on technique it eliminates airbubbles from
the equation? is this so? that would be good...but are there other sorts of
errors that occur or do you get perfection first time every time? because
obviously missing out the inbetweeny stages you not only eliminate the hard
work but you also eliminate the chance to correct errors before getting to
expensive silicone. so...are there just no errors, bumps, lumps, missing
bits, thin parts, bubbles, cracks dents, etc? or is it an expensive thing to
learn with and you only get good results after practising for months? or can
someone with no experience of silicone (or minimal) pretty much read the
instructions, mix and apply with a really good result each time?

Do you test for skin-sensitivity each time? do you get all models to sign
lengthy and scary looking legal documents? I know everyone should, but i
don't yet feel comfortable asking people to do this. I feel it promotes
mistrust and the idea that 'something' is dangerous that contradicts what
I'm telling them is very safe. If i don't have confidence in a product, I
won't use it...rather than risk it but protect myself with legal documents.
So...I'd love to use these new silicones...but I am still nervous about it
having heard some of the industry greats over here complain about them. Like
I said, I'm not pointing the finger at any of Ed's products...I think it was
a completely different brand...but I just want to make sure they really are
as safe and cost-effective as the promotion on the packet before i buy a
sample.

thanks for all help/info in advance.

CJ

Jeeesh CJ you ask so much. But you are asking the right questions. I will do
my best to answer.

First, you are not talking about ArtMolds products as LifeRite is brand new
and not available overseas. It is only now coming out of the California F/X
studios where it was undergoing field testing.

Ply-O-Life has been on the market over 12-years. It is (was?) the industry
standard before Body Double. Platinum and surgical silicones are used as
implants under the skin, chins, cheeks, bums, breasts. There are some people
who have an allergy to silicone tin and platinum. No matter what the claim
err on the side of caution.

Topical application of and skin-safe material must first be tested on the
back of your model's wrist (the most sensitive non-private part area). One
each model . . .and if you do not use a release form . . you are an accident
waiting to happen. Every artist needs a release from their model (See ALI
LIbrary)Wait 10-minutes and remove and inspect. Any skin discoloration means
there is a reaction . . . don't use the mold material.

CJ refers to yellowing and/or bruising. Matthew Mungle reports such
experience using Body Double on a well known Hollywood star. The material is
not very soft to improve tear resistance. However, the result is that it can
put a bruise on the bridge area of the nose upon removal (silicones have a
greater suction than alginates). These bruises required makeup application
for several days during the shot. Yes, they were yellow in color.

SkinRite was formulated to be more kind to the face and is softer. But
nothing is for free. As SkinRite combines two catalyst ingredients to
provide softness and superior tear strength it is much more sensitive to
contamination. Meaning the surface set will be inhibited and remain tacky.

All platinum's are inhibited by sulfurs. Sulfur in clay as well as sulfur
ingredients in body lotions and hand creams. This is especially true for
aloe-based cosmetics.

Therefore, it is important to wash the skin and dry it well before
application. Even better are alcohol pads.

Application: All manufactures (we too) indicate best results are obtained by
diluting the first coat of silicone with silicone oil (10% plus/minus). This
allows a smoother more bubble free application. That is followed by a second
application of a non-diluted layer (no oil). There is more of a tendency for
these products to contain air bubbles as they go on thicker than alginates.
The artist must therefore be a bit more careful in the application for best
results.

Yes, you need a few practice runs before you get the hang of it. But that is
so with any new material.

A final comment: The three manufacturers of skin-safe silicone are
conscientious reliable companies. Formulas are not fixed, they continue to
improve as field reports are received. Body Double has reformulated several
times. So what you heard then may not be true now. The Stan Winston Studios
in California swear by it so it can't be all bad. And it isn't. There are
materials for every application. When the application is right . . .
experiment with all brands of silicones . . .then you can choose one that is
right for you.

Hey ALI we just added a new piece to the ArtMolds Collection. It is by
Canadian artist Jamie Brick. The sculpture stands 30 inches tall and 20
inches at the shoulder. The stand is an antique silver vase and the leaves
in her hair and bodice are cut from silver plates.

Thanks for so really great questions.

Warmest regards

Ed.
There was one question that CJ asked about silicone rubber used on the body.
Is it safe to use on pregnant woman? I've always used alginates because I
was once told that the Platinum based silicones will be absorbed by the mother
and then of coarse the baby. What have you heard about this?

Thanks for providing this forum for all of us.

Subject : RE: Silicone mold

Dear Robert

Yes, Robert you right. My apology to CJ. I missed that question.

There have been instances of negative silicone reaction when surgical grade
silicone was implanted under the skin over long periods of time. LifeRite is
applied externally on top of the skin. It sets very quickly (5-min) so it is
not active long enough for even absorption. There has been no instances that
we are aware of the material being absorbed so deeply that it can be
transmitted to a fetus. It stays on the surface. You must check for rare
platinum reaction though using the back of the wrist. Once the silicone has
setup it is inert.

Here is a quick report on injectable silicone:

Adverse granulomatous reaction after cosmetic dermal silicone injection.

Bigata X, Ribera M, Bielsa I, Ferrandiz C.

Department of Dermatology, Hospital Universitari Germans Trias i Pujol

Universitat Autonoma de Barcelona, Badalona, Spain.

BACKGROUND: Various alloplastic injectable implants have been developed for
soft tissue augmentation without surgery, but different local or systemic
adverse reactions have limited their use for cosmetic purposes. OBJECTIVE:
To examine the problems associated with silicone injection. METHODS: Case
report and literature review. RESULTS: We describe an adverse granulomatous
reaction after the injection of liquid silicone for lip augmentation

causing facial disfigurement. Although the initial response to steroids was
poor, after 3 years of follow-up the nodules have almost disappeared
spontaneously. CONCLUSION: We advise that silicone injection be performed
solely by trained physicians using medical-grade silicone or consider other
injectable materials.

In other words nodules.

Here is another:

Case Report
Tissue reaction to liquid silicone simulating low-grade liposarcoma
following lip augmentation
Alexander Maly1, Eran Regev2, Karen Meir1, Bella Maly1

We report the case of a 32-year-old woman who underwent silicone injection
into the upper lip 2 years prior to presenting with masses clinically
suspicious for tumor and interpreted on biopsy as low-grade liposarcoma.
Lack of pre-operative history of silicone injection almost led to
unnecessary surgery. This complicated situation may arise when reaction to
liquid or gel silicone histologically closely simulates a low-grade
liposarcoma. Clinical and pathological correlations are of critical
assistance in making the correct pre-operative diagnosis and avoiding
unnecessary traumatic surgical intervention.

And another:

Unusual Skin Reaction to Silicone Content in Breast Implants

Acta Dermato-Venereologica 26 May 1999, vol. 79, no. 2, pp. 136-138(3)

Marcusson J. A.; Bjarnason B.

Abstract:
We present a patient who had a long history of unsuccessful bilateral
mammary operations with insertion and extraction of various implants, some
of which were filled with silicone gel, others with saline. In addition to
complications in the tissue surrounding the prosthesis, she had distant
widespread skin lesions which, we believe, were due to leakage from the
implant. A cutaneous test with material from various implants, such as the
gel content and the shells, caused an unusually prolonged inflammatory
response, which was difficult to classify as being either irritative or
allergic. Macromorphologically and histologically, the provoked lesions
resembled the previous cutaneous lesions. We believe that the patient's
complications are due to an unusual host response to silicone.
