Thank you for joining us here at As we do another instructional video and today we're going to cover a very fun medium. And that is Easy Molds two part Silicon Mold Putty. So what I'm going to do is first off I'm going to take off rings I have because I'm going to be kneading the mold putty in my hands. In the kit you're going to have part A which is a white substance and then part B which is purple. What's nice is as long as these are not touching they'll stay pliable and fresh for very a long time. I'm going to open them up. Unlike when you're doing resin and you have two part resin. You need the measurement to be really exact. You don't need them to be so exact with the mold putty. You just need to eye ball it and have approximately the same amounts of putty. You take the two units. You squish them together. This is why we took our rings off. You wanna work relatively fast. You have about one minute. Go ahead and kneed it together or trying to remove are all these white striations. You do just one mold at a time. I have a plate here, from our kitchen which is a non porous surface. You don't want to use a paper plate. You don't want to use newspaper print. You just want to use a non porous surface. Go ahead put that down. Again working pretty quickly. You have about three minutes now total. Go ahead depress a button or whatever you want. Let it sit there. Now we're going to wait twenty five minutes for that to cure. Once that is ready and we will go ahead and pop out our button. So in the meantime I'm going to make another mold. That was really how quick and easy that was. That took no time at all. Now that that was a really easy because I could just depress it down into my form. With this little skull button, I'm going to do a little different technique cause I want to shape it around the head. Because I've want his features to be distorted at all. I'm to go ahead and put my ball of clay on top of him. Instead of like pressing it here and dragging it over and I'm actually going to take some from the sides and roll it over him. Now I wanna make sure that I have enough because in a moment I'm going to make sure that he is sitting on a flat surface so that when I do fill the mold, stay straight. So now I'm just going to push him down like so. Make sure it's flat. Now I'll let him dry. Go ahead and push that down. And now I'm taking a rubber stamp. These a million of these out there and you're probanbly wondering what to do with all of them. You can go ahead and make molds. I'm going to leave that like that is. Again wait twenty five minutes. Twenty five minutes have ellapsed and we're gonna go ahead and release our original objects from our molds which are now set up. It does only take twenty five minutes which is really hard to believe but it is true. A very interesting thing happened when we were away. Here our rubber stamp mold took a tumble which is a good thing to be cognizant of and be aware of. we can't use this more but it does show that we need to be cautious when we do have an object that is taller than it is wide or really top heavy or bottom heavy. That we have to be careful that it is in a complete up right position. So I'm going to go ahead and release this. Just to show you what it would have looked like. Now unfortunately I can't use this but we know not to make that mistake again. But our other molds are fine. I'm going to take the first one. Just going to go ahead gently pull on the sides. It's very flexible I'm going to pop out our object. Do the same for our skull. You can see we have have an impression in there. So if you're going to go ahead and use polymer clay with these you can go ahead and use them right away. If you wanna use resin then you need to wait for twenty four hours. So what we've done is, we have actually, I'm going to show you a variety, here are some other molds that we made. We made a little airplane. Made a couple other buttons. This here is a little vintage jewelry component that I had. Made a little mold of that. We actually even molded a branch from outside. A couple troubleshooting tips is one you don't want to press down so hard that these tips, these edges that actually goes through to the bottom. What will happen is it will create a little hole and if you're pouring resin it's going to leak out the base. You're not going to have an object that's going to come out the mold cause it's all going to drain out the sides. To prevent that, don't push down too hard, you can go ahead and take some tape or some packaging tape flush up against your mold. The sticky side attached to the mold. Go ahead and press it into place. Then lay your mold flat again and that should seal up that hole. Another thing you want to be cautious of is if you have something that, you got to make sure that there's a complete round bowl shape, so that will you need to fill it it all stays secure in there. You don't want to have a slit down here or part if it that doesn't encompass it. You also want to go ahead and if you pull an object out of the mold and has perhaps have a rough edge just take a diamond file. You can file it down. I hope you can have a lot of fun making many molds using Silicone two part Mold Putty. Go to for all of your beading supplies needs!
