is the head life size? if i were to make an armature for a sculpture this size, how tall would you recommend the middle stand to be

How dry is the clay sculpture before doing the mold making?

Silicone will stick to a firm surface, but there is no need to wait till the sculpture is bone-dry.

Yes, one kit is more than enough for this size head sculpture. Here's another video you may like - lifedrawing.academy/life-drawing-academy-news/how-to-sculpt-portrait

Thanks for this video - great content. I’m wondering if I should fire my clay sculpture first - does that complicate the mold making process?

@DrawingArtAcademy 3 ай бұрын

No need to fire. Also, after firing, your sculpture will shrunk in size. I believe this is not what you want.

Thank you so much for this. I have a question 🙏🏾 Can this same hollow casting technique be used for a full figure? If yes; how can that be possible if there is hardly an open buttom to see how they are spread. Lastly, How do we evenly distribute the casting materials for a full figure?

@DrawingArtAcademy 8 ай бұрын

Yes and yes

Does this exact process work with oil based modeling clay? Wondering if the silicone would react different with modeling clay.

@DrawingArtAcademy Жыл бұрын

Make sure that your clay does not contain sulphur, which inhibits silicone hardening. Otherwise, oil based clay is good for the job

@remeisarat 3 ай бұрын

When you finish with the silicone mold, should you let it cure before doing the hard plaster mold? And if you don’t have modeling clay to separate the two hard mold halves, is there another material you can use? Thank you!

@DrawingArtAcademy 2 ай бұрын

Yes, the silicone mold has to ready for the hard mold. You can apply plaster bandages on top of liquid silicone. Check out this video to see the answer to your second question - lifedrawing.academy/life-drawing-academy-news/how-to-sculpt-portrait

I wonder if the plaster is heavier. It would be cool to color the plaster

@DrawingArtAcademy Жыл бұрын

Yes, it is heavier because the casted wall is thicker. And yes, you can tone the plaster model

@devanzummallen5677 8 ай бұрын

If I may ask, do you recall what silicone pigment you used for changing the color of your mold?

@DrawingArtAcademy 8 ай бұрын

Just search for "silicone paint". Any color would do for coloring a mold

could i fill in the plaster sculpute with plaster of paris to make it solid?

@DrawingArtAcademy Жыл бұрын

Of course, you can. It will make the bust heavier though

@JohnK-ih5kj 7 ай бұрын

Do you fire the sculpture in the kiln before or after you make the mold or not at all?

@DrawingArtAcademy 7 ай бұрын

Thanks for asking. This is WED clay, which cannot be fired. If you use another clay, there is no need to fire, unless you want to. Keep in mind that after firing, the sculpture will shrink in size, which you do not want for a mold.

@chantommy2735 2 жыл бұрын

is the touch feel cold (like metal) or warm (like plastic), using this method ?

@DrawingArtAcademy 2 жыл бұрын

Cold casting means that all materials are casted cold without melting

@LonxKong 2 жыл бұрын

It'll feel warm like plastic. As the very thin layer of metal powder won't conduct heat as effectivly as real cast metal.

@jfollender 3 ай бұрын

How many copies / sculptures can you make with this silicone mold before it loses integrity? Thx

@DrawingArtAcademy 3 ай бұрын

Thanks for asking. It depends on silicone, mould shape, plaster and release agent. You can make hundreds if not thousands of cold cast copies before good quality mould would break, providing that you do not stretch it extensively during remoulding and do not use abrasive materials such as concrete, for example.

I would love to see how you sculpted the base of the sculpture. I always struggle with that part. It seems you just used clay for the entire thing.

@DrawingArtAcademy Жыл бұрын

This sculpture was done entirely with cheap WED clay. However, this one is different - kzfaq.info/get/bejne/qrp9epd4xtzcqJs.html - because wax clay is expensive the base was done in plaster.

Can I use this mold technique with slip? For ceramics?

@DrawingArtAcademy 2 жыл бұрын

Yes, absolutely

@fluffy_chickadee Жыл бұрын

No you definitely can't. Silicone won't suck the moisture out of the slip. Plaster casts are used for ceramic slip

Do you recall approximately how much silicone and resin was used for this?

@DrawingArtAcademy Жыл бұрын

No, I do not remember. But how it would help you unless you make an exact replica of this bust? Every model would require a bit different amount of silicone and resin. Just use a common sense and a bit of calculation.

@ryannadler2617 Жыл бұрын

@@DrawingArtAcademy I'm thinking about making a similarly sized piece soon and wanted an approximate real world example so I could start budgeting for materials cost

@h7opolo 10 ай бұрын

weigh your sculpture, and convert the clay material's density to volume by dividing the sculpture weight by its density. This will be the volume for the amount of casting material, resin in the case of this video. For the silicone mold calculation, approximate the surface area of the sculpture to a regular geometric shape with proportions, i.e. height, width, and depth, matching the maximum values of the sculpture. In the case of the video, perhaps a cylinder's surface area would be a wise choice, in which case the volume of silicone would be greater than 2*Pi*radius*height*desired silicone thickness.

@grahamlang9344 Жыл бұрын

Do you have to wait the full 6 hours I’m between coats of silicone?

@DrawingArtAcademy Жыл бұрын

You can apply the next coat of silicone as soon as the previous is touch-dry. If you wait for too long, two layers won't properly stick to each other. You are welcome!

@@DrawingArtAcademy I guess what my question should be is, why use two completely different materials? What's the purpose/reason for the combination? Thanks!

@DrawingArtAcademy 2 жыл бұрын

High quality material forms the outer surface of the sculpture, but because this layer is thin, cheap plaster is used to build up the thickness inside. This simply save the cost.
