There are so many different effects that can be achieved with metals: Adding a patina, texturing, shaping... The sky is the limit! All textures and finishes can be created easily on a budget, so you don't have to spend a lot of money for great looking results!
There are so many metals and tools to work with and results to try, which often makes it daunting when starting out, so we've put together a few ideas in this post to help get you started and learn to navigate all the different colours, thicknesses, materials, and pre-textured metals like Mokume Gane and Crinkle Metal
When starting out, we would recommend you use a metal such as copper. Being cheaper, copper can allow you to practice and gain experience with a relatively small budget. Once you have gained confidence and experience with copper, you can move on to more valuable metals such as bronze, and silver.
All of our metals are available in various thicknesses, but we do recommend starting out with something thinner, as a thinner sheet metal is more flexible and easier to manipulate. In the same fashion, once you master your technique with a thinner sheet, you can then move onto thicker and more difficult materials. This will allow you to improve your skills before moving on to something challenging with confidence.
Every metal has unique properties and will react in different ways. This means that depending on the material you use, you can apply the same technique, and produce completely different finishes. For example, if you were to apply a heat treatment to copper, you'll produce completely different results than if you were to do the exact same thing with a sheet of brass.
Once you've experimented with different textures, tools, thicknesses, and materials, you're sure to find a finish you love that you'll want to use over and over!
Mokume Gane is produced with blended layers of copper and silver folded over one another. Once flattened, this produces a pattern quite similar to wood grain. In fact, the Japanese "Mokume Gane" closely translates to "Woodgrain Metal".
Silver crinkle metal is treated so that it reacts to heat. When you apply a torch to the surface, it will crinkle and produce a texture wherever you need! it can be used to quickly apply a fantastic rough-bubbly texture on any design you're working with.
Bending, shaping, texturing and cutting metal will cause it to harden as you work. This is completely normal, so don't worry if your material becomes too difficult to control, you just need to employ a process known as annealing.
Annealing is the process of softening the metal, allowing it to be worked easily. To anneal your metal, you need to apply heat to the surface using a gas torch, until the whole thing glows a soft red. You must then quench the surface in cold water. You'll then find that the metal is once again soft, and easier to manipulate. You'll soon learn when you need to anneal your metal!
There are various ways to cut and shape your metal. You can start with just the basic tools and add to your toolkit as your interest and skills progress. We have some great ideas for expansion in our 'build a toolkit' section of the site.
To start, you could employ a set of Metal Sheet & Wire Cutters. These are brilliant for cutting through anything up to 0.6mm thick, which is perfect for anyone starting out as you'll need to start thinner to practice.
If manually sawing your metal doesn't sound like fun, there's also the automatic option! A Dremel multi-tool, fitted with its cutting blades, can saw through any metal with ease.
To create perfectly sized discs of metal for your designs, you'll need the disc cutter tool. Simply insert your metal sheet under one of the punches, and tap with a hammer, and it will punch out a perfect circular disc, at your chosen size.
Adding a texture to your metal can give simple shapes a dramatic finish, and the texture applied will depend on the tools used.
Using the chisel edge of a Cross Pein Hammer, however, will produce lines in your work. When used extensively, this hammering of lines will result in a bark-like effect on the surface of the metal. The Jeweller's Hammer is much a lighter design and can be used in the same technique. As the hammer weighs less, it will give a more subtle result.
For a sturdy working environment, that won't be dented or damaged by your hammering, we recommend using a steel bench block as the perfect surface to place your metals when hammering. Please don't leave big round hammer dents in your dining table!
One fantastic method for texturing your metal is to fold it and hammer your texture, then repeatedly open and fold your design, continuing to hammer, until you have a totally unique design.
If you're looking to create dips and rises in your designs, consider using doming punches. If these are used on different surfaces, it will produce distinct effects. For example, using a doming punch to texture your metal against a bench block will create an even depth hammered effect, but hammering against a rolled up piece of leather will create a deeper and more uneven texture. Experimenting will produce new creative ideas and unique styles. To create clean spherical shapes in your piece, you can use the punches in combination with the doming block.
To engrave your own designs into metal, you'll want to use some Gravers. When attached to the wooden graver handle, you can gently hammer these against your metal to create marks, engravings, lines, and textures. These marks will then look even more distinct if you choose to apply a patina to your metal.
Creating patinas is an exciting way to add colour to your design! Let's explore some of the options available to us when we're looking to add some extra personality to our metalwork designs.
The first technique is heat treating. It's as simple as using your gas torch to apply heat to the surface of the metal you're working with, and you'll see a different effect depending on what metal you're using. and how much heat you applied to it. Every metal will have a unique reaction to heating, and produce different colours as a result. for example, we've found our gilding metal will become a beautiful golden amber colour when heated, and copper will give fantastic autumn sunset hues, producing oranges, reds, and even purples. The depth and shade of this colour can be controlled by varying the heat. Move your torch closer or further away from the surface, and feather the flame, to achieve very different colour variations than if you were to hold the flame in one place. As soon as you see the colour you want, immediately douse the metal with a thick wet cloth, to cool the heating process, and stop the colour change.
Get creative with heat colouring by texturing the metal first. By hammering the metal before heating, you'll produce a new mottled colour pattern that aligns with your hammer marks, completely different to the uniform colour you'll see on a flat surface. You can also use the Glass Fibre Scratch Brush to create etched pattern textures on the surface of your metal before heating. The angles of the scratches will catch the light in different ways, and produce an almost hologram styled coloration!
And last but certainly not least - Possibly the best thing about colouring your metal with heat is that it can polish off if you're not happy with the result, meaning you can practice until it's perfect!
Using chemicals like Liver of Sulphur (LOS) you can create some fantastic colours and effects. Again these effects change depending on what metal you have used as well as what dilution of LOS you have used, the heat of the solution, and if you have used heat treatment on the metal beforehand. There are so many variables, it presents endless results!
Using a very strong solution of LOS can create a black patina which looks great when applied to metal that you've textured or engraved. You can then polish the surface, whilst leaving the patina to remain in the recesses, creating a dramatic contrast in your design. You can even mask off the areas you don't want the LOS to affect.
For more information on patinas, metal texturing, and coloration, we highly recommend this book from Matthew Runfola. Metal Patination Techniques For Jewelers And Metalsmiths is absolutely packed with fantastic finishing ideas, with every metal and variation you could dream of. We had a great time looking through this book when it came in stock; it gave us lots of new inspiration and it's wonderfully presented with high-quality pictures of every single finish! It's certainly worth checking out if you feel this is a subject you're interested in.
