I want to make fridge magnets for the people in my brain injury workshop.
Love this idea and purpose!
I was hoping to cast some brains in resin....or something...I don't have a clear idea of how I will do this.
If you want to cast with resin, you can still make a mold but it would have to be from 2-part silicone putty
. It's flexible, takes very good detail, cures quickly, is highly heat-resistant, and nothing much ever sticks to it. If you want to read about silicone molding materials, brands, characteristics, etc, check out this page at my site:http://glassattic.com/polymer/molds.htm
(click on 2-Part Silicone Putties
(....although there's only been one brand of 2-part silicone molding material available *locally* at craft stores, etc--Amazing Mold Putty-- there is a new brand becoming available now too and hopefully it will be higher quality, though you may not need high quality...can't remember name but it might be purple; or you can check my page for better brands of silicone putty online)
If you want to make casts in a mold though, you can easily use polymer clay
instead (plus polymer clay can be made any color, texture, etc, as well as have inclusions and simulate just about any other material there is from ceramic and glass to wood, pearl, metal, stone, jade, etc., etc.).
Polymer clay can be made into the molds themselves, and also used as the casting material in those molds or in other kinds of molds. That's actually done all the time and it's great fun to boot. Here is a pic of some of my molds (and some of the casts from them) in a previous post of mine, plus more info about doing it:http://www.craftster.org/forum/index.php?topic=101292.msg960710#msg960710
I also don't have the patience to make a brain out of polymer clay.
If you don't want to make a simple brain as a form for creating the mold, you could probably have someone else on Craftster or in another polymer clay forum make one for you, especially since it will be for a charitable purpose.
Or you can shop at Halloween places, for example, for brain earrings, rings, jewelry, or little decorations/etc (at this time of year though probably mostly online).
You could also find brain stamps
or you could create brain stamps in various ways with polymer clay, or create stamps by finding one or more brain drawings you like and sending the drawings off to ReadyStamps**, etc. When you get the stamps back, press them into polymer clay to make the frig magnets*** (then perhaps "highlight" or "antique" the impressions, etc, to further decorate them).
You might also like "brain canes"
made from polymer clay as a classy image for some of your magnets. Brain canes can be cut as thick slices then have a magnet put on back, or thin slices can be placed onto balls or other areas, etc, of polymer clay then rolled into the background so they become part of the clay. They can look quite different depending on color, complexity and technique.
Here are some examples, and instructions:http://www.flickr.com/photos/dolphinplay7/4657695424

canes subcategory which is under the Layers
category, then scroll down to the parts on "brain canes")
I was also thinking of just using a picture of a brain and embed *that* in resin...
That would be cool too. For info about putting an image under resin
, in several ways, check out this page as well if you're interested:http://glassattic.com/polymer/other_materials.htm
It would be easiest to use epoxy
resin, glue the image to a base of some kind (even baked polymer clay), elevate that item, and pour the resin on top allowing it to drip off if necessary...or you could pour the resin into a permanent "cell" of some kind which would contain the resin (with the image underneath).
You could also use some kinds of molds with polyester
resin (more fiddly and less good for lungs) or certain kinds of epoxy resin, and cast the images upside down as "embedments" in the resin.
Then glue on the magnet, perhaps using 2-part epoxy glue (pretty much the same as epoxy resin).
is my favorite place to have this done... you send them a sheet of paper on which you've drawn/photocopied/printed/whatever (b&w) as many designs (including text if you want) as you can fit into a 9 1/2 x 7" rectangle plus $35, and they'll send you back a 9 1/2 x 7 sheet of rubberstamps of your images (they'll also include the "plate and matrix" or reverse mold, if you request).
You can then cut the stamps apart and use as is, or mount (temporarily or permanently) on blocks of wood or plastic sheets/blocks/boxes.
It's a great deal and can be quite addicting to have that much power . You can read more about how ReadyStamps works here and get a direct link to them:http://www.polyclay.com/ready.htm

HTH, and best of luck with it!
