Hi this Julie with and today I want to show you how to use Easy Mold Silicon Rubber Mold Making Kit and this is a liquid mold. Inside the kit you're going to get a set of instructions, part A and part B of the silicon rubber. You're going to combine those two make your mold. But before we begin I want to show you everything you need for this project. You need some rice and this is just household rice. You need some polymer clay and it needs to be sulfur free. A product like Sculpey is sulfur free. That'll work fine. You can also use hot glue from a glue gun and I'll show you what we are going to be doing with that in a moment as alternative to the Sculpey. You need a stir stick. I've laid down some protective sheeting and I actually got a little piece of white paper here as well because I really liked working on white. It's a little easier to see. You're going to need a object to make a mold out of. We have a great funky plastic bangle so that what we're going to make a mold of. You need an exacto knife, a pair of scissors and a measuring cup which is going to be the same cup that you're going to stir your silicone in and you need a plastic container. This is just a disposable one You can get this at the grocery store or use a yogurt container. Any container gonna work as long as you can dispose of it and cut it. Those are going to be the two characteristics you need and you need to make sure that it has a nice flat lid part to it. So let's begin. First off what you want to do is first determine how much of the silicone rubber you're gonna need because we don't want to mix all of this. That's gonna be wasteful and you're gonna wanna make other projects with it. So to figure out how much we're going to need we're going to take our container. When we actually pour our rubber what we're gonna do is have it in this type of orientation where the bangle is resting on the lid not on the base. But for measuring purposes we're gonna take bangle, put it in the bottom of the cup and here is where our rice comes in. Pour your rice over your object. Squish it around a little bit make sure it's fully covered. I'm also remembering I'm gonna have this flipped over so I need a little bit more than what's actually here but looks pretty good. It's fully covered. The top part of the bangle is not poking through it all. I'm going to fish my bangle out take the rice pour it into a measuring cup. Now I want to add a little bit because I do you want to compensate for the fact that it's going to be in a upside down position that's got a wider diameter to it. I'm going to make this easy on myself I'm going to go to the eight ounce mark. Now when you making a mold it's going to be totally different measurements for whatever your making but for the purposes of this video I know I'm going to need about eight ounces. Take my rice get rid of it pour it back into the bag. Whatever will work. And now what I would normally is I'm going to clean this cup thoroughly. I don't want any of the residue from the rice to be in this cup but just for the purposes of this video I'm going to grab a clean cup. You don't have to waste that many cups. One cup is going to work for all of this. So next I want to cut off the base of my container. Make an incision with an exacto knife. Now if you're really comfortable with an exacto I just like to make a little cut with the exacto and then I take my scissors and cut. I'm going to discard that now. Now here's where the Sculpey comes in. You need to secure your object to the base otherwise it's gonna float or you're going to get a lot of the silicon rubber underneath it and that's going to be a problem when you try to get the object out and you want to pour your mold. So you can use a sulfur free clay or you can use a hot glue gun we have the clay on hand I'm going to go ahead and use it. I'm going to condition it with my hands just by rolling and squishing it up You need to do this for a few minutes until it's really quite pliable. It's good to go now. So I'm going to now roll it into a long tube shape just roll it out on the table I can tell that's going to be too much and that's okay You can reused the clay that we're not gonna be using for this project. The clay that we are using for the project you're going to throw away afterwards. Stretch it. In a moment I'm going to trace along the edge I'm trying to get as thin as possible because I don't want it to really affect the look of my mold too much. A glue guy would probably be easier and a a little quicker. This works fine I'm happy with what I have and I'm going to take my bangle and I'm just gonna place this along the edge and pressing into it I want to create a bond take this flip it over center on my plastic lid and press it down. I actually can feel a vacuum affect right there so I now I have a good seal. I'm going to take my fingernail right now just trim this up a little bit because I don't want it affect the look of my mold too much. It's ready and I return the body part of this piece of plastic tupperware push it down firmly and now I am ready to mix up my silicone rubber. Take part A I'm going to do four ounces because remember we need it to be eight ounces in total Grabbing part B it's bright bright blue grab a clean stir stick and I'm going to fill this to eight ounce. I am noticing that the white is settling but it looks like that white went more to the five ounce than the four. Not quite sure how that happened but I'm gonna have to add more of the blue part B Kinda keep that in mind as you're working. Keep an eye on what's going on it looked like it was at the four ounce now it's looking much more like five ounce. It's just going to fit. Now we're going to start I'm going to stir until all the colors are fully blended. It's going to take you about three-four minutes to get this fully stirred together. You can see we have a consistent blue color. There's no streaks of white in there. It's ready to go and unlike the silicon rubber mold puddy we only have a couple minutes to work with it You have about forty five minutes to an hour to work with this so you're gonna have plenty of time. Now we're going to pour it into my mold. It better to pour it on a side not in the middle. That's going to help to push out the air bubbles. We're also going to hold the cup well above our project. I'm not going to pour down here but way up here. I want to get a nice, thin stream going. That's going to help allow the air bubbles to escape and your pouring it so it doesn't get caught in the mold. That looks good and you're going to let that cure overnight for twenty four hours and then we'll come back and we'll finish our mold. We've waited patiently for twenty four hours. You can see that our mold is solid now. It's just rubber No blue is coming up on my fingers. This is completely cured Now you can see why we actually poured it with the lid being the base because what we can do now is flip it over and take the lid off of the bottom here. So this is going to be the top of our mold and now we need to cut away the sides you can do that with the exacto knife or you can use a pair of scissors. Totally up to you. You see that clay rim that we made which sealed the bangle to the actual lid. Now we're just gonna pop the bangle out. Once you've removed your object from your mold you want to clear away any of this clay dust. I'm just going to go ahead and wash my mold let it dry and it'll be ready to pour some resin.
