HOW TO MAKE A COMPLEX MOLD for Sculpture - Silicone and Hydrostone / Plaster, Handmade Mould

In this in-depth video I discuss prepping the sculpture for silicone through adding a backboard, considering final fit to the clock project and applying a Krylon crystal clear finish. This video covers applying the silicone, mix ratios, additives, wait times, shimming and tips for a more successful mold. This video is 1 of 2 for the mold making process. The mother mold is covered in part 2.
I’ve decided to take on this project I considered years ago. However, I want to add a sculptural element to the top of my clock. I have been inspired by the Dream Lady sculpture at the Lincoln Park Zoo in Chicago. I will cover the basics of incorporating the sculpture into the clock design, Simplicity, by Clayton Boyer. I’m breaking this series into 4 videos. Part 1: concept/design and armature design. Part 2: clay and modeling. Part 3: casting the sculpture and cutting out the gears. Part 4: finish and assembly. Thanks for coming along!

One thing I like about John’s videos is that he takes the time to explain every little detail, he goes into depth so that you understand exactly what he is saying. Good job John.

An icing bag with nozzle seems like it would be a clean and fast way to apply the lines for the cuts.

I suppose that's another way to approach it. I like to say, there's 101 ways to make a mold. Thanks for your comment. I hope others can benefit from it.

Can you explain the technique of how the German "Allach" porcelain figurines were made? I'm fascinated by their detail and they did not have modern materials like silicone. I have a kiln that goes to 2200f and would like to attempt making a small detailed figurine if possible.

@JonBurnsFineArt Жыл бұрын

Considering I've never made a sculpture this way, I have experience with slip casting and those types of molds. These molds are simple two or three piece molds. The clay (porcelain) slurry called "slip" is poured into molds dry held together by straps or bands. As the water is drawn into the plaster the clay shrinks and is then poured out after a few minutes. This is repeated several times until you get the desired thickness. Take the hollow castings out at the leather hard stage, trim and attach your odd parts with more slip and a brush. Clean it up and fire to the clay body's temperature.

How many trial kits of Rebound did this takes? I’m casting a sculpt similar to size but using Smooth on Dragonskin 30. Much more flexible. Give it a try.

@JonBurnsFineArt 3 жыл бұрын

Dave Silva! Your name sounds super familiar. Honestly, for a project this size, I would get 4 trial kits if you cannot order the gallon kit (You might get away with 3). Because it's A:B ratio, the gallon kit is actually 2 gallons worth. That's why the price is higher all around (more product = more molds). That and it has platinum in it. I hope this info helps. On a separate note, I'll take a look at Dragon Skin again. A friend talked about it in grad school but I never used it personally. Thanks for suggesting it.

This project was fascinating and going to try it but my model that i want to recreate has a problemas it has a hole in the middle, was wondering how you would compensate for this and could give me any hints thanks

@JonBurnsFineArt 2 жыл бұрын

Hey Wullie. Thanks for the compliment! It was a very fun project. Tackling molding sculptures with a hole(s) can be arduous. But there are several routes. I'll tell you here, but not explain more than that. 1) plug the hole and drill it out later and mold as normal, 2) put silicone in the hole and when demolding, pull the silicone out as far as you can and serrate cut the silicone, 3) cut your sculpture in multiple pieces as to "expose" and eliminate the hole. I hope one of these ideas puts you on the correct path. ☘️

hello! did that sculpture went to the oven before you made a mold for it?

@JonBurnsFineArt 3 жыл бұрын

Nope. This is an oil based Clay that is generally referred to as plastilina or plasticine Clay. An oven would have destroyed it. I do have several videos on making it. kzfaq.info/get/bejne/nbODY5WArJuVen0.html I hope these answers your questions.

Outstanding explanation of the process with great visuals. Wish presenters would include a visual clue on their videos to indicate when the soundtrack stops and the speaking resumes or begins. Otherwise, envy the talent and the results.

I was wondering if you know whether it would be possible to mold a sculpture of a women with tentacles for her legs in one piece using this method.

@JonBurnsFineArt 2 жыл бұрын

In a word, yes. If you attempt this, I trust it's not your first time using silicone. This will take some finesse. Without knowing what your sculpture looks like, my instinct is to approach it like an umbrella shape with the skeletal part of the umbrella being the tentacles and the fabric as the separation line in the silicone. Concerning the top portion, try to keep it to a two or three piece mold. I have several videos showing how to consider parting lines. If this all seems overwhelming, just mull it over for a few days until you're comfortable with the idea of your approach. Best of luck!

Why rebound and not dragonskin or moldmax?

Hi ! BY chance do you create custom molds? I would be able to send you the actual product and pay for the services of course. I will appreciate your response

Sorry, no. Look up your local foundry. They can usually assist in these matters.
