this is the best video explaining mold making and casting i have watched so far. surprised it has this small number of viewings

Great work. Wow. Did you only use 1 kit of the Rebound 25 silicone? Was it enough?

You are amazing

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

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?

How dry is the clay sculpture before doing the mold making? Thank you!

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

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

@DrawingArtAcademy

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

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

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

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

@DrawingArtAcademy

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.

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

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!

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

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

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

@DrawingArtAcademy

Cold casting means that all materials are casted cold without melting

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

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

@DrawingArtAcademy

4 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.

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!

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.

@h7opolo

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.

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.
