My New Secret Weapon for Making REALISTIC Rocks?!

[@andrewbriggs2279]

i only clicked on this as i saw the name "geordie" .Being from england i expected a person from newcastle ( a geordie) to host the video. im so glad i clicked on it, one of the best vids ive seen in a long time and the enthusiasm you have is a breath of fresh air.

[@rebeccacbrown13]

This is the most realistic result I've ever seen. Making your own plaster molds with real rocks seems so obvious in retrospect, but I've never seen it before!

[@izzyjones7108]

I've done it, used real rocks pressed into foam rock shapes...

[@LeonhartTryhard]

I got a better textures doing it without molds or electric tools

[@rain4825]

About plasticine, for those who don't really know the product, it's kinda like a playdoh that never goes bad. you can just sculpt whatever and reuse it for later. It is not made to make permanent stuff by itself. Some key points: it works with heat, the hotter it it the easier you can work it (that's why it's no use using force, just keep it in your hands will soften it), once you've sculpted something you like, you can just put it in the freezer for it to harden. It is used as a mold in this video but you can otherwise make molds of things you sculpted with it, like plaster or silicone. the kind I use is safe for children as it is not toxic, but make sure when you buy, also it comes in different hardness, the harder are generally better for detailed works and the softer are (obviously) easier to shape and mold. With use over time, it will keep on assimilating impurities, which can be resolved by heating it until it becomes liquid, then sift it. Do mix it afterwards before letting it set because the componants can separate in liquid state. (that's how it goes for mine, do check to make sure for yours). I got mine years ago so I don't know how expensive it is nowadays, but it is infinitely reusable, so unless you're sculpting something enormous, I'd recommend giving it a try.

[@MaranataSamsudi]

Great info man. What's the difference with dry clay das , which one stick better with plastic toys?

[@rain4825]

@@MaranataSamsudi I don't use Das clay so I wouldn't know. From what I understand, das clay is air hardenning, which would mean that once you've sculpted it into your desired shape it is a finished product, and cannot be reversed to its previous state. It feels to me that the comparison is not relevant, since the two products ultimately have different usecases. Plasticine is not meant to make permanent stuff with, unlike a hardening material like air drying clay. Hopefully this makes sense to you.

[@boblangford81]

So your saying Plastacine assimilation is a lot like the Borg from Star Trek minus the death and destruction. As long as it doesn’t start muttering, “resistance is futile”, then I should be safe.

[@youtousim]

For someone wanting to be less product dependent, cork bark is a nice alternative for Rock for formations. Learned a lot, thanks for the in depth guide!

[@blakelycreative3171]

The plasticine tip is really helpful. I like mold making but the steps and time required can be frustrating. This is the perfect solution. Thx!

[@penguinparades]

It is always a good day when you release a video! I've done this before with old sculpey polyclay I had lying around that was too dry and dirty do use for sculpting. Definitely make sure to wash your rocks thoroughly, any sand or dirt will stick in the mold and may lower reusability. Also use harder rocks that won't crumble and make a mess in your mold, those were annoying lessons to learn. I definitely need to find some plasticine for future projects. Thanks for showing it!

[@Geordiecrafts]

That's a good suggestion! I didn't clean my rocks before pressing them into the plasicine, but it would definitely help over the long run to keep the plasticine clean and good to use! Thanks for the tip 😊

[@TerrainTronics]

Fantastic advice on the plasticine. I'm thinking of making some columns soon, but I don't really need/want to make proper silicon molds for a 1 off project. One of the thoughts that popped into my head when you spoke about the rocks vs plaster is that when you make the plasticine molds as you did, you'll always get a flat back to the rock. Useful for getting as much surface area attached to the foam! On the downside, it does mean that you can only mold flat bottomed items.

[@Geordiecrafts]

Yeah plasticine is great for those one off projects! That's a good point about the columns, a bit of a limited application but still workable 😊

[@rain4825]

Just do 2 halves of a column and glue the flat sides together afterwards, maybe?

[@Geordiecrafts]

Thanks Nick! I had a blast! 😊 (explosion pun intended)

[@robinred1851]

When you want an unendless variety of rockmolds use aluminium foil used for grilling. It's much thicker than normal kitchen foil and wider. You can get it in width up to 60 cm. To test it just take a piece of let's say 30x30 cm and scram it together. Not to tight, you should be able to pull it apart again. From this scrambled piece make a form so you can pour plaster in it, just like you would do with a rockmold. With this method I have made rock-faces up to 50x40 cms. 💖From the Čech Republic🇨🇿

[@HO-bndk]

Coffee grounds. What an absolutely brilliant idea for colouring the basic groundwork.

[@loydcogswell294]

As a scale model builder of Armor, I use a ton of different techniques to make my Dioramas. I’ve used a similar technique in several projects, and I’ve found that if I use acrylic paint in the plaster of rocks and other objects it serves a few purposes. First it makes painting and dry brushing easier, and second if someone accidentally touches and breaks a plaster piece it’s not plaster white and easier to repair. Good tips in your video though 👍🏻👍🏻👍🏻

[@NatesMiniatures]

This is so good! I thought I'd have to make complex messy silicon molds to utilise real rocks but this will be perfect for what I want to do. I think if I mash a bunch of rocks into the plasticine and add some reinforcement material I could make large cliff wall pieces. Thank you!

[@RealTerrainHobbies]

Well, that Plasticine mold is pretty dang amazing. Well done Geordie, really great video and awesome edit🙌

the little beads of moldable plastic work really well, too. lay it over some rocks to get a mold. when you want another shape just drop the plastic back into hot water and make a new mold.

[@stevestogsdill5791]

Marklinofsweden used landscape bark mulch for rocks on a train layout. I bet they would also work well for making impressions in the plasticine.

[@Geordiecrafts]

Oh yes that would probably work great! Thanks for the suggestion 😊

[@alandouglas8939]

Great video Geordie. Plastercine is geat. I have used it for over 50 years. Its great for mold making as you have described. I have actually used it with resin. If you use Epoxy resin (Like Envirotex Lite) then this does not get hot so will not melt the Plastercine mold. You can also use Plastercine with Polyester resin for small molds as it will not get too hot. The molds are destroyed with resin and the molded item will have some Plastercine stuck to it, but a wash with lacquer thinners will remove it easily. Also have you tried Mod Podge for sticking down your grass? Mod Podge is a PVA type product but you can buy it in Matt as well as Gloss. Matt works great for grass as it is not shiny. Keep up the videos.

[@YADUSHREEBRIJ]

Great art for making miniature Rocks

[@lovecontemplation8607]

As someone I just watched made their own sculptamold that looked to be absolutely amazing and also dirt cheap. Find Cellulose insulation, and use that with plaster/gypsum, as a substitute for sculptamold.

[@warrenarmstrong2154]

You can add black or brown or whatever colour of paint to the white plaster that way if it breaks it is less noticeable

[@Jam_66]

Love the way you filmed this video! Great work

[@Stephen-rk2to]

Just an old tip I've used for years. Instead of using real small rocks, use cat litter. Its light weight and cheap.

[@poilaaliop]

Perlite is also a good option, and even lighter!

[@LancerThomas]

Cat litter absorbs moisture (kinda what it’s designed to do) and degrades over time. I’ve seen the results of cat litter used as scenic materials and it’s not pretty.

[@Stephen-rk2to]

I have scenery I made for war gaming from 35 years ago that is still fine. I have no idea what you're talking about.

[@lilpain1997]

@@Stephen-rk2to Kinda useless to use that stuff though when you can get small rocks for really cheap anyway. Wont have the issue of them potentially degrading and its not toxic which from knowledge cat litter can be.

[@Stephen-rk2to]

@lilpain1997 like I said. It's cheap and I've never had any issues with degrading. 6 bucks and I have a lifetime supply of "rocks" that don't degrade and looks fantastic.

One point you may want to try....when first cutting cliff faces try scrapping a drywall saw @ 90° to the surface since the teeth are at different sizes it will make more non uniform ( realistic) tears

[@rolandhersom239]

For my sculptor mould, I shred several sheets of soft toilet paper in a nutri bullet and I get nice fluffy paper. Wear breathing protection so you don't inhale the dust when you open the bullet. Add about an inch or so of plaster to a jar and fill loosely with the paper fluff. Shake vigorously to coat the fluff with the plaster. Take out what you want and mix with water to the desired consistency and wella! You have a very inexpensive alternative to Sculpted mould. Can be shaped, carved and painted in the same way and is fast drying so don't wait too long after drying begins. Moulds for my rocks were made by painting silicon rubber onto carefully chosen real rock surfaces. Apply about 4 coats and reinforce the final layer with gauze bandage. These moulds are very flexible and able to be used in various locations to suit requirements. I lay the mould flat and pour a fairly soupy plaster mix onto it ensuring that all depressions are filled. I wait until a semi gloss sheen appears on the surface and mild heat can be felt when touching the setting plaster. The mould is then able to be carefully lifted and slapped onto the surface where you want it. You are able to poke and prod it as you want to whatever shape you require. When toe outside of the mould is quite warm to the touch, the curing is sufficiently advanced to allow you to peel the mould away. The plaster is still soft enough to allow any removal of unwanted flash repair of any minor imperfections that may have occurred such as a small blowhole. Spray the surface the mould is to be applied to with water to ensure god adhesion. These silicone rubber moulds last for decades if washed off immediately after removal and when finished, an application of talc helps to increase their life. I also wet the mould before pouring as this to eliminate air bubbles forming as the plaster spreads across the mould surface. The plaster casting is best kept reasonably thin for economy and ease of handling and flexibility.

[@JiluMiah-ek2rd]

One the most simplest and of course, realistic I’ve seen so far. I’m thinking of building a rock mini crawler course for indoors. Seen some examples they’re using but I want to use foam as a base. To keep it light as possible and adding/remove terrain as I’m testing the course. I like the mix medium element in this diorama. But this is the first time I’ve seen someone use grout and a brush!! 👏👏👏 awesome. oh and plasticine

[@davidbauman4705]

I’m impressed, never seen the plasticine before

[@lilcwa]

Is there any need with plasticine molds to use some kind of mold release compound when pouring plaster, especially if you intend to pour additional plaster rocks from the same mold after you de-mold the first batch, in order to avoid deforming your mold of having bits of plasticine come off on the completed plaster rocks?

[@Geordiecrafts]

I tested this a few weeks ago and used the same mold 3 times and didn't have any issue with plasticine sticking to the plaster, they all came out clean! (Without using any mold release)

[@edeaglehouse2221]

In addition to what Geordie said, even if you warp your molds, it will give you a more natural result because things in nature are never perfectly identical. Unless, of course, you are trying to replicate identical pieces. Then, just keep your molds concave and take care when removing the castings.

[@NigeyWigey]

Ok that plasticine stop motion bit got me. Great use of materials!

[@davidcurtis5398]

When making rock molds consider using tree bark chips. You can get a very large bag at a "big box" store for about $5.If you look at the chips you can find a lot of them that will look just like rock. You can put several together and make a mold or just use them on as rocks. They work either way.

What's the name of the tool that helps cure glues in tricky small areas by blowing puffs of air. It should also control the exposed area, temperature, and flow of air speed

A long time ago, when I was a snot gobbler, I had some Airfix WW1 German soldiers. One of the figures was of a dead guy with a flat back, I pressed him into some Plasticine and dripped sprue melted with a candle into the mould and left it to cool down. When I pulled the new figure out it had almost perfectly reproduced the detail on the figure. I only ever attempted this once as the melting plastic made a proper stink in my bedroom and I was terrified that my mum would notice it.
