How to cast Bronze?
you have come to the right place...
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The method described in this manual is called the thin ceramic shell, lost wax technique. There are many other methods to make a bronze figurine but the lost wax, thin ceramic shell method is the easiest way for the home founder to make a small sculpture to a high degree of quality at little cost and with easily found tools and materials.

This is the same method implemented by professional art foundries. We have simply scaled it down and adapted some aspects of the process to make it easy for anyone to complete successfully in a few days without any heavy equipment.

This manual is not attempting to delve into details of all the principles and all aspects of the bronze casting technology. We will rather focus on a simple yet rewarding project that will allow the novice to cast a small piece safely, quickly, cheaply and to a high degree of quality. More advanced casting techniques are discussed in the second part of the book.


Numerous diagrams illustrate every step.

The manual is a 114 page downloadable PDF file. (29Mb). You will need a PDF reader to open, view and print the file. If you do not have a PDF reader, you can download one here for free.

Or order the paperback from amazon.com.

What does the manual cover?
The tutorial takes you through all the steps necessary to make a small, fist size bronze sculpture, from making the original sculpture in wax to finishing the final bronze reproduction.

The manual will introduce you to the basics of wax working, "sprueing" a wax model, mixing and applying a ceramic slurry, making your own crucible and making an efficient yet affordable furnace, melting and pouring the metal and finally chasing the bronze before applying a simple patina.
 

Advanced casting techniques such as hollow casting are discussed in later chapters of the manual. Here is the table of contents.
 



The entire process is documented in color photogarphs.

What tools and materials are required?
Most of the tools and materials you will need are fairly easy to find, you may even have them already. However you will also need some more specialised materials that are more difficult to source:

  • Bronze metal. You will need about 3kg of silicone bronze. This is generally sold in ingots by metal merchants. You can also buy off cuts from your local foundry.
  • Calcined kaolin, or fused silica flour and stucco sand. A refractory material that is the basis of the ceramic shell.
  • Zircon sand. Zircon is a naturally occurring refractory mineral. It is used as stucco for the first layer of the ceramic shell.
  • Colloidal silica. This is a water based binder to be mixed with the refractory material. Ludox SM Colloidal Silica is the most commonly found.
  • Wax. Used to make a wax pattern of the sculpture. In our case we will make the original sculpture in wax.
  • Ceramic blanket. A refractory fibre blanket used to construct a temporary furnace.
  • A LPG Gas torch. This is used a source of heat to melt the metal. You only need the same gas cylinder as to fuel your BBQ. You can borrow or rent the torch for one day.

To make it easy to find these tools and materials, an appendix lists a large number of places where such tools and materials can be purchased in different countries around the world. (UK, US, Canada, ZA, OZ, NZ, France, Ireland and more...) This will save you much time and effort and will allow you to quickly gather all necessary materials and equipment.

How much will this all cost?
You should not have to spend more than $300 and perhaps as little as $100 depending on what you already have and on whether you buy or rent some equipment.

 

How many people are needed?
All steps can be easily managed by one person and no particular physical strength is required.

"Brilliant manual. Olivier takes one through each step very well and provides information in a clear manner. As a result of Olivier's instructions I am now getting good castings of my engine parts. Most recently I have cast two pistons for an engine I am rebuilding. I have also recently cast a beautiful elephant ornament. A must have manual for people interested in casting their own pieces."
Sam, USA

"This is an excellent and simple book which enables you to cast bronze WITHOUT! building a complicated furnace, genius! Very good book which I can recommend and by someone who clearly knows his stuff."
Thomas, USA

I have by now cast 50-100 bronzes using your manual, I am very happy about it :-)
Helle Rask Crawford, Denmark

"A year ago I purchased your great (and reasonably priced) publication, on casting bronze! Thank you sir! I think your publication is the best how-to book of information, for artists I have seen. And I have seen a good number in 33 years as an artist.

I have made a number of attempts to work in this medium before and they all were frustrating, you have provided the big picture, as well, your innovations are clear and well thought out! Thank you for avoiding "artspeak"
Jim Stokes, Alberta, Canada

 "...one of the best books on the subject and will become the foundation standard of small time casting in the future."
Glen P. Michigan
 

I am a big fan of your work. I bought your bronze casting manual and I must say that it is a very interesting read.
Vic du Preez, Foundryman, NZ
 

The book is very good. Well written and fun as well. Not too much information to absorb at any one time and definitely a great guideline”
J.Worsell – Auckland
 

Very complete coverage. I think a person with reasonable skills could definitely accomplish the cast by following the instructions.”
David Robertson,
Artist Blacksmith

 

“I found your instructions and video very clear indeed. The whole project was successful - much better than I expected for a first attempt. This was due to the excellence of your manual.”
Roger B, New Zealand
 

" I have at least 25 books on casting, wax work, no counting the books on pattern making etc. I have reviewed casting books from both sides of the pond, and now both ponds.

This one will become an instant classic and a corner stone of a new direction in the small home shop backyard casting.

I think anybody that reads this book will find it to be one of those head slapping ones, for being one of the best KISS (Keep it simple stupid) books on a generally complex subject. "

How much time is needed?
The project will span over 5 days but it does not have to be 5 consecutive days. You could work one day a week over a 5 weeks period if you prefer. The project consists of the following steps:

  • Sculpting. You will first be making a small sculpture in wax. It is essential that it is made in wax. Please do not start making a piece in clay or other molding material.

  • “Sprueing” The wax figurine will then be prepared for the mold. You will continue to learn the basics of wax working.

  • “Shelling-up” The wax will then be encased in a ceramic mold, called shell, which is painted in its liquid form in several layers over the wax and then left to dry

  •  “De-waxing” Once the shell is dry, you will use a gas torch to melt the wax out of the shell. This is called “de-waxing” or “burning out”. You now have an empty negative of your original shape - a ceramic mold.

  • Melting and pouring. A simple temporary furnace needs to be built and metal melted inside a crucible before it is poured in the empty shell. This is the most exciting part of the process. Do not be intimidated, our method is both safe and easy.

  • “Knocking-off” and “Chasing” Once the metal has cooled and solidified, the shell can be knocked off to free the newborn bronze sculpture.  It now needs to be cleaned and any imperfections smoothed out. This process is called “chasing”.

  • Patina. Finally, the new sculpture must be given a surface finish. This is known as patina. Bronze will naturally oxidize and acquire deep and rich colors known as “Patina”. This is a very slow natural process that can be considerably accelerated. The manual will demonstrate the most common patina techniques.

More advanced casting methods are described too.

All measurements are expressed in both metric and US customary units. Pricing indications are expressed in US dollars.

 

Even though this is a fairly safe process, there is always some risk involved in working with power tools, flames, gas cylinders and molten metal.  Necessary health and safety precautions will be clearly labelled throughout the manual.

About the author
A New Zealander since 1987, French born Olivier Duhamel lives on Waiheke Island near Auckland, New Zealand with his wife Marie-France and their 3 children.
He is a sculptor specialising in the female human form and makes delicately crafted small bronze figurines.
After having been introduced to the fine art of metal casting by sculptor and founder David Reid, Olivier has set up his small home foundry and has since cast over 500 pieces using basic tools and ingredients. He takes pride in the quality of his castings.
Olivier Duhamel’ s creations do not convey any particular message, do not attempt any conceptual or symbolist exploration, nor do they search to be innovative at all cost. They are rather trying to simply capture the beauty and sensuality of his subject of study.
His bronze works are sold in art galleries across New Zealand and also in Australia, China, France and Belgium.
