Silicone casting?

Are there any good (and cheap) kits available for casting silicone? Endless options for making high quality sextoys.

I use the silicon in tube (310 ml Soudal or similar, the clear is a bit better - softer).Cover your hand with the soap and make a desired shape and smooth surface.Let it stand to next day on a ventilated place - it smells like vinegar.

If you not will use the whole content, so you can use come filling to make a basic shape and then use a silicone.I use a PVC drain tubes.

I think is possible to really cast something with this silicone, because it really plastic, nearby fluent.

The best way i have found to make molds for silicone is call the lost material method mainly used in manifacturing custom car body parts .. starting with hobby styrofoam also called oasis make your shape with sharp knife and sand paper it really sands super easy may not even need or want a knife .. next prep a tub or bucket with quick set plaster found at all hardware stores or light weight quick dry spackel .. insert toy shape in to plaster the same way and direction you would in your body leaving the end of the foam exposed that will not contact your body .. leaving this as a fill spot .. then once dry using acetone pour it on the foam melting it like snow empty all signs of styro from mold make sure to clean well and carefully with 4-1 baking soda water mix .. let dry. next fill mold with 5-1 silicone cornstarch mix ...(it is dificult to get even mix with the starch with will add strength to the silicone and add durability totally worth it)only do 1/2 to 1 inch layers letting sit for at least 1 hour between layers depending on temp i my self wrap my molds in a heating pad or even aim a good heater at it to speed set up time once you are all done with your fill process after 1 hour remove heat let sit 24 hours .. to remove toy from mold simply smack the sides with a hammer breaking the plaster .. if it will not fracture simply do your best chipping it away to as close to toy as you can get and then soak in warm water .. and use tooth brush to clean of extra plaster that may stick .. next clean toy with a 3-1 mix of water rubbing alcahol and a few drops of grease fighter dish soap .. and your done .. with this process you can also incoperate vibrator motors in to the layers .. or my favorite led,s being as how the silicone will be white and semi transparent ..
