How To Cast Anything With This Two Ingredient Mold

Sometimes it’s just fun to play around and create for the pure joy of it — case in point this little concrete pear. When our blog was MIA a few weeks ago, I went into a total downer. And when this girl gets down, she goes shopping for food. Anyone else do that? So while walking around our local store, I spied a plump, little green pear with the cutest butt ever. Weird, I know. If I’m not feeling up tin cans to make a washing board I’m checking out the butts on pears 😀  Anyways she came home with me and rather than chopping her up for a fruit salad, I decided to make a “two ingredient” mold, and turn her into a paper-weight instead.

Ever wanted to make your own silicone molds? All you need is two ingredients and you probably have them at home already. #mold #mould #concrete #DIY

Kinda cute right?!!! She’s been drizzled with a rich copper paint sauce. If I ever master the art of cooking I’d love to make a baked pear dish with a drizzle of sauce. It looks like something that could be served in a 5-star restaurant. Okay, maybe not 😉 So since the only recipes I know how to follow are those that involve a strange mix of ingredients, let me share how to make a mold, using only two ingredients that can be used to cast almost anything.

But before we get to the tutorial, be sure to follow us on Facebook, Twitter, Pinterest, and Instagram. And don’t forget to subscribe to our monthly newsletter so you’ll never miss a post!

Two Ingredient Casting Mold

  • Silicone
  • Maizena or cornstarch

The Other Stuff

  • Whatever you want to mold. I used my shapely pear 😉
  • Plastic knife for mixing
  • Mixing container
  • Caulking gun
  • Sharp knife
  • Super Glue
  • Gloves

Prepping the Form for Molding

Wash and dry the pear, or whatever you decide to cast. Since I’ll be filling the mold with concrete once it’s dry, I stuck a pen lid into the bottom of the pear. It helps keep the pear upright while the mold sets and will leave a hole that’s the right size for pouring in the concrete mix later.

See what I mean about the cute pear butt 😉 I stuck the pen lid into a bit of polystyrene before mixing up the mold. It’s a trick I learned when painting polystyrene balls 😉

Mixing the Two Ingredient Mold

Put your gloves on and throw some cornstarch into a container. Cut the tip off of the silicone tube and put it inside the caulking gun. Squeeze some silicone into the cornstarch. Roughly the same amount. Then add some more cornstarch on top of the silicone and stir using the plastic knife. It’s probably best to do this outside. Silicone has an incredibly strong vinegary smell. When it looks like it’s almost mixed, start kneading the mixture until it forms a stiff paste that resembles bread dough.

If the mixture is too tacky or sticky, add some more cornstarch. If it’s too dry and flaky, like in the piccy above, add more silicone. Once it’s ready, flatten it out a bit and wrap it around the shape you want to cast. About 7 to 10 mm thick is perfect. That’s about 1/4” to 3/8”. Make sure you squish it into all the nooks and crannies.

Sit back and wait for it to dry, probably about ½ hour depending on the silicone you used. Use a sharp knife to cut the mold and remove your form. The two ingredient mold is very pliable so you can just peel it off. If you’re molding a pear, please don’t eat it. Rather wash it off again and add it to the compost heap.

Use super glue and carefully glue the two halves back together again, and it’s ready for casting.

Casting the two ingredient mold

You can either use concrete or plaster of Paris. I didn’t have to add any kind of release agent, I simply mixed up some concrete and poured it inside the mold. Just make sure you shake it around a little to get rid of any air bubbles. Once the concrete sets, carefully cut along the seam lines and remove your form.

The two ingredient mold can be reused over and over again, just wash it off, and you’re good to go.

To finish the pear off, I used some copper paint to create that 5-star restaurant look and added a bent, rusty nail as a stalk. The leaf was cut from a piece of metal that’s been lying outside in the rain for a few months.

A little bit of rust always works for me.

The easy two ingredient mold works really well and can be reused over and over again. And I do so love that combination of concrete, copper, and rust.

Just a word of warning. Once you make your first mold, everything looks moldable 😀 We’ve turned an old broken doll into a garden ornament and even created our own Egyptian cartouche using the two-ingredient mold.

And if you like the idea, don’t forget to save it to Pinterest so that you can find it again!

    Michelle--Im thinking of using this type of mold to make stuff out of liquid polymer clay...can it be safely baked in an oven while the clay is still inside the mold? ...LOVE this stuff! --Marjie in Illinois

      acraftymix

      Oh my Majorie, that's a very interesting question. I have no idea. I've never tried to bake something inside the mold. Mmmmm, I do have a green pepper mold lying around some air-dry clay. Let me test it for you and I'll let you know.

    Silly question...how did you attach the stem? Your pear is absolutely beautiful!

      I'm so happy you like the pear Sheryl and no question is ever silly. I drilled a hole into the top of the pear and then glued the rusty nail stem inside

    I never knew mold-making could be so simple! Are there substances other than concrete which may be used in this kind of mold?
    • Posted: November 5, 2019 11:55

      acraftymix

      Hey there Kathy, we've used plaster of Paris and resin in the molds and they both work well.

    Angela

    Hi, I'm glad I came across this tutorial as the ingredient list is way less than other tutorials I have seen. Do you think this mold would hold up to isomalt usage?
    • Posted: October 28, 2019 04:51

      acraftymix

      Hi Angela, I'm sure it would, just look for food-safe silicone. It's a bit more expensive though. The silicone I used was the really cheap stuff and has a strong vinegar smell, so that's probably not a good idea for isomalt.

    Therea

    I have a question-do you think this could work on larger objects? Trying to make a mold for a moose horn to use for a memorial for my late father-in-law? Would it work w/large box/crate?
    • Posted: October 5, 2019 04:49

      acraftymix

      🤔 I'm not sure Therea. The biggest thing we molded was a large cast-iron pot (30 cm tall or about 11,5"). We had use a lot of silicone and cornstarch to make the mold so it was strong enough to hold the concrete we put inside. The mold had to be mixed in batches so it didn't dry out too. I've never seen a moose but I believe they're really big and looking at pictures of their horns you'll have to think carefully about how to cut the mold off so it can be joined together again. They're quite intricate with all those curls and whirls. I hope that makes sense and I'm so sorry for the loss of your father-in-law 💞

    Hi Michelle, Thank you for lifting my spirit. i'm an addicted crafter like you. Use to make teeth out of porcelain and gold and other metals. Well the crafter in me started to take impressions with dental materials. The victims were herbs little branches with berries, insects. Yes anything small that would fit in the casting machine. what fun and cute and beautiful things I made. I all so made castings with alginate impression materials and plaster of my sons face when he was 15. He still has it. NOW your impression material is much cheaper and I am retired now, so this is just for me. I have a little trick to make things rust fast. Vinegar and salt 2:1. Spray or dip iron things leave 24 to 48 hours, you have rust. Now a question? what paint and technique did you use for the copper drizzle? Thank you again I'm following you.
    • Posted: July 23, 2019 05:08

      acraftymix

      💓 And you just made my day. I so enjoy getting beautiful comments like yours. Wow, those casting that you did sound so incredibly interesting. I wish I could see them. You have my mind going all over the place right now, just thinking about all the fun, natural stuff out there I can experiment with. Thank you so much for the salt and vinegar recipe too. I'm going to give it a try. WRT the paint, I used copper acrylic paint and poured it on in layers, waiting for each layer to dry so it could have some "depth".

        Karla Toles

        Thank you for the inspiration. I have a small ceramic turtle I want to make from cement. I hope I can do as good as job as you did. I'm apprehensive to make the mold because of how my turtle has the legs and head. Unlike the the pair that is just one solid cavity.
        • Posted: September 28, 2019 05:09

          acraftymix

          Hey there Karla, I'm sure your turtle will turn out beautifully. You may need to figure out where the cut the mold off. It's difficult to give advice without a picture of the little turtle but I would try cutting the mold around her middle if that makes any sense. So you'll end up with a front half and a back half. You can leave a hole at the top for pouring the cement. That way it will fall into the legs first. Be sure to shake her around every time you add more cement so it goes into all the nooks and crannies and her head area. I'm not sure if you saw the wood nymph that we made using the same mold - https://acraftymix.com/blog/wood-nymph-garden-ornament/. She's about 1 1/2" (4cm) and all the details are spot on, even her teeny, tiny little nostrils. Just experiment and have fun.

    You sure were right about the pear butt! What a clever and attractive paperweight. Using the rusty nail and scrap tin for the stalk and leaf is genius at work. Just beautiful!

    Oh Michelle, I've somehow missed this post. This is sooooo cool! I had no idea that you can make a mold with these ingredients. Thank you so much for sharing! Right now I don't have an idea for a mold but I will certainly keep this method in mind.

        Fo you think this would work on a small animal skull? I find quite a bit of things nature has left behind while landscaping.
        • Posted: October 12, 2019 04:50

          acraftymix

          A small skull might be tricky Kayla, but worth experimenting with. I would probably cut the skull in half lengthwise before making the mold. You can glue the two bits together after casting. That way you should get all the details and skulls are usually pretty symmetrical so you'll have two molds to experiment with. Just an idea, I haven't tried molding a skull before

    That looks quite impressive Michelle! So you used a real pear to mold around? I like the rust application at the end too. It looks sort of like a gourd. I had no idea it was that easy to make molds. Now you can make no end of things to put out in your garden.
