I used Play doh for the clay, & I bought one of those Lego bases & I used Lego's to make a 2 part mold. I also used a plastic cup, Glued down part in the middle for Then I poured the liquid around it taking shape. You can use plastic cups & legos to make the mold box too.
Thanks i was looking at one guys youtube hours searching until yours showed up. On the two part step.. Most ppl just show them putting the resin in the rtv. Thanks 100x
Thank you for this video. It is very helpful. I am a new silicone artist making silicone dolls. Do you use ecoflex 20 platinum cure to make this mould? thank you
What type of clay have you used? Or any soft clay could be used? I want to make mold from plaster of paris idol, so should i first coat it with something? or I can directly pour the silicone over it?
The bottom is completely open. You can see me pouring a cast in this mold in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Inw_dbBgghk.html
Thanks for this tutorial video, is your mold box made from Melamine Board? Do you know if making the mold box from wood is okay with silicone mold making and if it should be raw or treated in some way? Thanks!
My box is made of MDF that was coated with a very thin layer of Vaseline. The silicone shouldn't really stick to wood, but what can happen is that it gets into the grain and all the pores, making it a bit harder to peel away, and leaves a surface that's a little rough. A light coat of Vaseline is a quick and easy way to coat the wood. You can also brush on some shellac or even paint if you don't mind waiting for it to dry.
No glue, just clamps. You have to make sure the seams are sealed well. I usually spread some petroleum jelly on the walls of the box as a mold release, and that's usually enough for me to keep the seams sealed.
Hi I love your video - I plan on making a mold from a tin figure to make a cookie or chocolate mold. Is it dangerous? Will the chemicals/led go into the food grade silicone? Have you any tips for me?
