I have been meaning to write this information for a while.
I think it's very important for buyers to know ahead of time what silicone really is, what to expect and how to maintain it.
First is the Type. There are two types of silicone. Tin and Platinum.
Tin was the first silicone to be used in the doll industry. It was cheaper than platinum and easy to work with. Most earlier dolls were poured in tin.
There wasn't a lot of education on the lifespan of tin and those dolls that were poured in tin, today are breaking down. They become sort of like an eraser... over time they leech oil and lose their elasticity. The joints of dolls tear and the silicone can crumble. Some resemble pieces of cheese where mice or bugs have eaten through. If you one day pick up your doll and a finger/ toe/ head falls off, most likely its tin. The easiest way to know if your doll is tin is to paint it with some platinum silicone paint. If after 4-8 hours the paint just wipes away, it is tin.
Unfortunately, there is no saving tin. Some deteriorate at a faster rate than others but eventually, all tin dolls will fall apart.
* many ask what they can use to repair their tin silicone for a temporary solution or fix. Best silicone is SilPoxy by Smooth On. Its expensive but does the trick for gluing rips or tears on tin. Sometimes fish tank silicone caulk at Walmart works great too. Needs to smell like vinegar.
Learning from these troubles, doll castors changed to platinum silicone. Currently, experts say platinum will last time. And so far that is true. There has been no breaking down. All dolls today (with the exception of silicone dolls made in China) are poured in platinum. It is now a given.
EcoFlex, Dragon Skin, Rebound are all types of Platinum Silicone and are used for many molding, casting and pouring purposes. Most dolls today are poured in EcoFlex.
Second is Shore. Different silicone softness is called Shore. The higher the shore, the harder the silicone.
Older silicone was made of a harder silicone.... first in Dragon skin, 50 shore.
Then it became EcoFlex 50 (very similar to Dragon Skin) and next was Eco 30 and then Eco 20 and then 10.
Now some are doing EcoFlex 10 plus an additive called Slacker, which makes it feel like marshmallow. AMAZING feeling silicone! However, any additives to a solid silicone can weaken its original state. Things like pulling at a silicone arm would be more harmful to a doll with slacker in it. There is also a higher chance of the surface of the silicone giving off more oils (its called leeching, where the additives used to soften the silicone is trying to escape thru the surface causing it to be oily), therefore, altering the surface paint or matte, possibly causing it to come off over time. We are all still new to Slacker and the results over time and at this moment in history cannot guarantee its original state/shape/paint.
The interesting part about silicone is.... the harder the silicone, the more detail is retained... 50 is the closest to the original clay sculpt you can get in silicone. Once you hit shore 30 your detail starts to soften.
Someone asked me to write a piece on the feel of the different shore or what is termed Durometer Shore Hardness scale
50 shore ~ like a hard bendable eraser
30 shore ~ like squishing the palm of your hand or a gel insert for your shoes
20 shore ~ like squishing the fat pad between your thumb and forefinger
10 shore ~ like squishing your ear lobe or a gummy bear
Marshmellow ~ like a memory foam pillow or mattress
Third is Paint. The only thing that sticks to silicone is silicone. So painting a silicone doll must be done in a platinum silicone base. Silicone is VERY temperamental and if anything touches your silicone that it does not like, your paint won't stick.
Latex, nope
Tin, nope
Oils in hands, nope.
A rainy day with Netflix on but the volume is on low, nope...lol, just joking.. sort of.
Very temperamental with a mind of its own!!!
Here is some knowledge on painting different silicone softness. The softer the silicone, the harder it is to paint... think about painting on a canvas versus a wet noodle... It's HARD to get detail and retain it.
Also, when you paint a canvas the details stay unaffected. A line is a line.
But when you paint on a noodle.. or better imagined on a balloon... you paint a line and the balloon moves in your hand or deflates a little.. the lines on the balloon change. Sometimes they soften and aren't so defined.
The same is with soft silicone. Lines aren't as distinct on softer silicone. And now with the marshmallow silicone, it's one step softer and harder to paint and retain that clean line you can get on vinyl or harder silicone.
Additional Info: I've had questions about painting and it sticking. Why won't my paint stick? So there could be a few reasons. Are you painting tin? Cause your platinum silicone won't stick. End of discussion, lol
Has your piece been properly prepped and washed? Silicone Pieces sometimes have release mold on them and can't be painted until they are properly prepped.
Do you have oils on your hands? Do you have anything with latex around? Silicone paint won't stick if there is oil, dirt or latex on the surface. Some gloves say latex-free but can cause paint to not stick. True story, been there done that, cried over it!
Is your paint bad? Well, one way to tell is, if you paint is curing in its pot, it's not. If it's still wet after even an hour, it's no good.
Did you mix the right ratio of A and B? Exact amounts of equal proportions.
When you thin down your silicone paint it loses its strength.. don't make your paints too thin. They will peel
In the end, it could be your silicone piece. It may have touched something on the way to you OR your pourer may have prepped it with something that is reacting to your paint. If nothing else is working, talk to your pourer... it doesn't mean the piece is bad! and you need a refund... it just may mean they can problem-solve with you.
Matting on silicone,.... ahhhhh a silicone artists nemesis. Matting is the Fourth thing.
Silicone cures (dries) shiny. Matting dulls the paint to a matte. Most silicone mattes come in the form of powder. Matting silicone is done at the last stage of painting a silicone doll and is maybe the most cumbersome, death-defying stage of the whole process. It can make your baby alive or can ruin all your hard work and thousands of dollars worth of silicone baby... just in the matte.
Again, the softer the silicone the harder it is to matte. And the quicker the matte can be rubbed off. Now I've been doing this for 13 years and as much as I have perfected my matting skills, I still have a challenge of matting on every doll I create. The biggest problem is EVENTUALLY every silicone doll will get a shiny spot. Usually on the spots most touched... knuckles, knees, toes, chin.... All which can be rematted (given nothing has touched it so that the silicone won't be inhibited).. but it will happen.
Because there has been a HUGE craze with soft, soft marshmallow silicone right now, I am going to forewarn, paint and matte will rub off quicker than a regular 50 or 30 or 20 shore silicone. That SOFT silicone movement just changes the surface every time it jiggles. Again think about dried glue on a solid glass surface compared to a surface like a balloon. It moves and pulls up much quicker on a moving surface. And because the super soft marshmallow silicone is still new, there is still lots to be learned.
So the next topic is Maintaining a silicone doll. I include these instructions with all my dolls
- When you pick your baby up support them by the head and a hand on their back, never let the head tip back. If the silicone is Eco 20-30, the silicone can slip from the rings or joints.
- DO NOT pick them up by the arms or legs, they will tear or come loose if a cloth body or rip the seam in the armpit of a silicone. IF baby is 20-10 shore, the joints of the baby will tear easier. DO NOT pull or tug on arms or legs. IT CAN RIP AT JOINT.
- DO NOT force your Silicones arms into a position they will not comfortably go, this can cause tearing under the arms or inside near the elbows.
- DO NOT force the legs into a full sitting position this can also cause tears, do not bend the legs forwards at the knees as it can tear behind the knees.
- Be careful with your silicone’s hair, it is not sealed on the inside so some shedding will occur over time, if you ‘play ‘ with your baby then you will expect some hair loss. Brush gently.
- If your baby becomes a little ‘fluffy’ nearly all silicones will eventually attract dust and fluff, you can use a good quality makeup blush brush to dust off your baby and then brush over a fine layer of baby powder or matting powder) if your baby has any shine or makes dressing them easier. Usually, a little bit of tape over the skin will pick up any lint, as well.
- Some say it is all right to bathe your silicone and some do not recommend it. I do not recommend it. If you choose to, do not do it too often. It will wreck your paint (not the sculpts). Rinse well, do not rub hard or you can damage the paint. NEVER RUB YOUR SILICONE.
- Dry your baby carefully, pat dry, then leave on the towel and air dry fully, using a cotton bud make sure all the water is out of the ears, behind the ears and around the eyes, for open mouth babies make sure the inside of the mouth is dry.
- Do not pick or scratch or rub your babies skin. This will affect the paint.
- Continually rubbing, sliding (in and out of a pacifier) or touching (oily fingers) can cause the silicone to get a shiny spot or a paint rub.
- When dressing you can wrap the limbs with saran wrap first and then dress. It will allow the cloth to slide along the limbs easier and save the life of your paint.
- DO NOT use baby lotions on your baby.
- All Silicones have slight imperfections this is normal and is part of the OOAK making, mold making, casting and pouring and putting your baby together.
- When using a pacifier, only use a SILICONE nipple/teat, do not use a nipple/teat that is too large for your silicones mouth as it will stretch it. Gently place one pinky in the mouth and lightly pull open. Insert pacifier.
- Do not leave a magnetic dummy/pacifier on for long periods of time as this can dent the silicone.
- Make sure all dark and bright dyed clothing has been prewashed to prevent any staining on your silicone. Sometimes even after washing dark clothes, they will still stain. This also goes for anything they may come in contact with that is dark.
- Try not to powder areas of the doll that are meant to be wet or shiny looking. ie. lips, nails, eyelids. The powder can sometimes act as an abrasive against these parts and cause the silicone to peel.
- DO NOT use any latex products with your silicones, either sponges to paint, gloves or latex pillows, some baby pillows and mattresses are latex so its best to check as it will react with the silicone.
- Do not leave your silicones laying/sitting on a hard surface for too long. It can flatten the silicone.
- Do not leave a magnetic pacifier in one spot on the mouth for too long, it can dent the silicone. Softer the silicone, the more risk.
- DO NOT jam your finger (or let anyone else) into your baby’s mouth as the corners can quickly be split ~ tip by Laura Tuzio Ross
- If you have a drink and wet baby only use water to feed your baby. Otherwise, it could cause mold and mildew in your baby's insides.
- Even though one can make their paint as permanent as it can be, paint and matting on silicone dolls can be rubbed off if rubbed too hard or too often. They are not vinyl dolls and should not be handled as such. Their paint is still delicate and should be treated and touched with care.
If you are buying a baby to play with, play with them! Its fun and wonderful and that is why you bought it. If its more of a collector's item and you want to spend more money, then placing them in a glass shelf is fun too. I prefer my dolls looking sweet in their cradles.. not handled much but wearing the CUTEST outfits I can find.
My personal opinions and pet peeves?????
I don't think silicone babies should be bathed... rubbing on the paint only wears on them.
I cringe every time I see someone squeeze silicone babies cheeks and hands and mouths... I just worry about the paint. That is me.
The in and out of a pacifier could wear on the lips of a silicone babies paint... again, I worry about the finish.
So here it is. If you have any questions, write me and I will answer them the best I can and then add them to this list. We need to be informed before our purchases and we need to be informing of the dolls we are creating.
Many hugs, KrisC
