 IMPRESSION  MOULDING MATERIAL

Craft Mill Chromatic Impression Moulding Alginate is a one use material for professionals or modellers to make mouldings large or small of any body part like rows of teeth, hands, feet, breasts, penises.  It may have other uses but I am concerned on my web site with offering  the product used by modellers mainly for making mouldings of body parts.  It can also be used for modelling other things like ceiling covings or small sculptural items.  It is capable of producing fine detail down to creases in hands and finger nails but will not produce detail down to finger prints.

My Chromatic dental alginate has a pleasant dentist’s waiting room smell.  It tastes like a mild brand of toothpaste.  It is by  definition non-allergic as it has to be used safely in patient’s mouths of all ages.  It is easy to use because it changes colour at each stage of the process giving you visible notice of how much time is left to do each stage.  It can be used on any part of the body including external private parts. Chromatic alginate is made from seaweed.  the brand I recommend and sell has a relatively slow setting time.  The chart below gives you an idea.  

Dental Chromatic Alginate is super safe for using on the youngest child or most delicate body part as it is designed for use in the mouth to take dental mouldings.  the great thing about using it as well is it changes colour as you work it, telling you what stage you should be at from mixing, to applying, to setting.

If you buy moulding and casting kits or only the alginate, I supply  the appropriate help sheet. 

Baby Hand and Foot Moulding and Casting.  Adult Hand, Foot and oher small body parts

You have to get some small poly bags to pour in the alginate for baby's hand to be put in BUT I PREFER AN EMPTY DRINKS CONTAINER of a suitable size easily to fit the limb into.    It uses a bit more alginate but when pouring in the plaster, a drinks container stands firmly upright - bags don't. Gloves are not necessary as the set alginate peels off very easily. 

Those who know best say that 450g of Alginate will make up to 5 new baby hands or feet.  It will make one large adult hand and for an adult foot you need at least two 450g bags.  Remember the Moulding Alginate is for making the mould only.  After making the mould, you then need to make a casting from your mould.  To do this you need casting plaster.  An adult foot will require at least 3kg of fine casting plaster.  Making a penis moulding will use a similar container to that for a hand and depending on size, 1kg of casting plaster will be adequate for a penis casting.

On another advert, I supply a 1kg pack of Fine Casting Plaster which is ideal for the job.  1kg of plaster is more than enough to go with the 500g pack of Alginate. 

You may also wish to paint your finished casting  After making the casting let it dry thoroughly then paint gold, copper or silver (also supplied by me).  Finally you can varnish your finished product if necessary.  I also stock Satin and Gloss varnish.  For these products, please click on  Acrylic Painting Materials

Face Moulding and Casting and Breast Casting

Face Moulding and Casting is the next level of difficulty.  To do this you have to think about maintaining your model's breathing either through the mouth or nostrils.  Some people suggest straws but used in the nose with tender membranes, care should be taken.  Face and breast casting has an additional stage.  Having applied the Alginate to the body, after the alginate has set, at least 4 layers of Modroc Plaster of Paris Bandage must be applied to the moulding to secure its shape after removal.  Without Modroc plaster bandage the moulding would collapse when removed. the Face Mould or Breast Mould then has to be put in a supportive cradle for the Casting Plaster to be poured in.  You require 3kg of plaster for a Face Cast and a similar amount for a Breast Cast but this depends very much on cup size.

Craft Mill sells larger quantities of Casting Plaster and AND MULTI PACKS OF ALGINATE as well.  If you are in business making mouldings, you can buy 24 pack cases at greatly discounted prices..  I ALSO SELL OTHER CASTING AND MOULDING KITS.   Please click on  Casting and Moulding Materials  to view them.

Pregnant Belly Casting Using Modroc Plaster Bandage Only.

I strongly recommend this approach if you want to make a lasting memento of your big bump.  It is very easy to do.  You buy 8 rolls of Modroc Bandage and by following the included instructions, you can reproduce your bump successfully - but it is a negative.  If you want a positive, you can make a Papier Mache positive inside the negative Modroc moulding.  You have to  use cling film on your body before applying the Modroc Plaster Bandage.  I do a whole range of Modroc Plaster of Paris Bandages.  click on ModRoc Plaster of Paris Bandage to go to my shop

Casting a full Pregnant Belly torso neck to crotch

Pregnant belly moulding and casting using alginate the hardest of the castings to attempt.  It requires 4 people including the model.  It requires 5 bags of alginate and 25kg of casting plaster.  I do not recommend it for anyone but an experienced sculptor.
