What Do I Need to Get Started in Stained Glass Mosaics?

One of the questions I hear quite often from people who are interested in mosaics is:

“What do I actually need to get started?”

When you’re new to mosaics, it can feel a little overwhelming. There are so many tools, different types of glass, adhesives, substrates and supplies available that it’s easy to think you need to purchase everything before you can begin.

The good news is—you really don’t.

To get started in stained glass mosaics, you really only need a few basic tools: mosaic cutters, a glass cutter, running pliers, tweezers and safety glasses, along with some stained glass, a suitable substrate and the right adhesive for your project.

You can always add more specialized tools and materials later as you discover what you enjoy creating.

If you’re interested in creating stained glass mosaics, a fairly small collection of basic tools and materials will get you well on your way. As you gain experience, you’ll quickly discover which tools you use most often and what type of mosaics you enjoy creating.

So, let’s keep it simple.

The Basic Tools

Mosaic Cutters

If you’re going to be working with stained glass, a good pair of mosaic cutters will probably be one of the tools you reach for most often.

These allow you to nip and shape your glass into smaller pieces. You don’t need every cutter on the market when you’re beginning. One good-quality pair will take you a very long way.

Like most tools, there is a bit of a learning curve. Don’t expect every piece of glass to break exactly where you want it to on your first try. Learning how the glass responds is all part of the process.

Glass Cutter

A glass cutter is used to score the surface of stained glass before breaking it along that score line.

I personally like a pistol-grip style cutter because I find it comfortable to use, but there are several styles available. The important thing is finding one that feels comfortable in your hand.

Running Pliers

Once you’ve scored your glass, running pliers help you separate it cleanly along the score.

They’re particularly useful when you need to cut strips or larger sections of glass before using your mosaic cutters to shape those pieces further.

Tweezers

Nothing fancy required here!

A simple pair of tweezers makes it much easier to position small pieces of glass, especially when you’re working in detailed areas or trying to maintain tighter spacing.

Safety Glasses

This one isn’t optional in my studio.

Always protect your eyes when cutting glass.

Tiny pieces can occasionally fly when glass is being cut or nipped, so a good pair of safety glasses should be part of your basic setup from day one.

Choosing Your Glass

You certainly don’t need an enormous collection of stained glass to begin.

Start with a handful of colours you like and build your collection over time. Scraps and off-cuts are also incredibly useful in mosaics, so don’t be too quick to throw those little pieces away!

As you gain experience, you’ll also begin noticing the differences between transparent, translucent, semi-opaque and opaque glass, and how each one behaves in a finished mosaic.

If you’re creating a glass-on-glass mosaic, for example, the amount of light passing through the glass becomes part of your design. If you’re working on an opaque substrate such as wood, you may make completely different glass choices.

There really isn’t one type of glass that is right for every project.

You Need Something to Mosaic On

The surface you create your mosaic on is called the substrate.

Depending on what you’re creating, that might be:

• Wood
• Clear glass
• Plexiglass/acrylic
• A prepared frame
• Another suitable rigid surface

The important thing is to choose your substrate based on what you are creating and where the finished mosaic will eventually live.

An indoor wall mosaic and something intended for outdoor use don’t necessarily have the same requirements. Your substrate, adhesive and other materials should always be appropriate for the environment where your finished piece will be displayed.

Choosing an Adhesive

Your adhesive is another area where there isn’t one universal answer.

The adhesive you choose should be suitable for both your glass and your substrate, as well as the conditions your finished piece will be exposed to.

For my own work, I use different adhesives depending on what I’m creating. I use Prep Multi-Use Adhesive extensively for my glass-on-glass work, while Weldbond is my preference for many of my mosaics created on wood.

Whatever adhesive you choose, make sure it is appropriate for your particular application and follow the manufacturer’s instructions.

And remember—more glue isn’t necessarily better!

You want enough adhesive to securely hold your glass without having excessive amounts squeezing up between your pieces.

Not sure which adhesive to use? I’ve written a more detailed guide about the different adhesives I use in my own mosaic work and when I use each one.

 

 

And Then There’s Grout

Not every mosaic needs to be grouted, but for the majority of my work, my preference is sanded grout.

Sanded grout works particularly well with the spacing I typically use in my mosaics, and I like the finished appearance it gives the piece.

You certainly don’t need to purchase several different colours when you’re beginning. Start with a colour that works well with your project and build from there.

You’ll also need a few inexpensive supplies for mixing and applying your grout—a container, something to mix with, gloves, and cloths or sponges for cleanup.

One thing I always recommend is mixing your grout on the drier side—still pliable and easy to work with, but not overly wet.

Too much water can affect the final grout colour, and when you’re working on a wood substrate, that additional moisture can also be absorbed into the wood and increase the potential for warping.

For my own mosaics, sanded grout mixed with less rather than more water is my preference.

Want to learn more about grout? I’ve put together a detailed guide explaining the grout I use, how I mix it and some of the things I’ve learned along the way.

What You DON’T Need

This might be just as important as the shopping list.

You don’t need a studio filled with expensive equipment.

You don’t need hundreds of sheets of glass.

And you certainly don’t need every specialty mosaic tool you see online.

Start with the basics. Learn how to use them well. Then add tools and supplies as you discover what you actually need.

After more than 20 years of creating mosaics, some of the simplest tools in my studio are still the ones I use every single day.

Your Basic Stained Glass Mosaic Starter List

If you simply want a shopping list to take with you, here it is:

Tools

• Mosaic cutters
• Running pliers
• Glass cutter
• Tweezers
• Safety glasses

Materials

• Stained glass
• An appropriate substrate
• Adhesive suitable for your project
• Sanded grout, if your project requires grouting
• A container, gloves and basic supplies for grouting

That really is enough to begin.

Before you start shopping, take a few minutes to look around at what you may already have. Some of the basic supplies you need may already be sitting in your workshop or craft area.

Before You Buy Too Much… Watch My Free Tutorials

If you’re completely new to stained glass mosaics, I also have a collection of free, informal DIY video tutorials where I demonstrate many of the basics.

I originally created these videos to accompany some of my DIY mosaic kits, but you do not need to purchase a kit—or anything from me—to watch and learn from them.

They cover things such as using the basic tools, cutting and shaping stained glass, working with adhesive, placing your glass and other little tips that are often much easier to understand when you can actually see someone doing them.

If you’re just beginning your mosaic journey, I would recommend watching a few of those before investing in a lot of supplies.

Most Importantly—Just Start

Your first mosaic doesn’t need to be complicated.

In fact, I think you’ll learn far more by starting with a small, manageable project than by purchasing every possible tool and trying to tackle something enormous right away.

You will break glass in ways you didn’t intend. You’ll place pieces and later decide you might have done them differently. You’ll discover colours you love working with and tools you reach for constantly.

That’s how you learn.

I’ve been creating mosaics for more than 20 years, and I’m still learning, experimenting and occasionally looking at a finished piece and thinking about what I might try differently the next time.

That’s part of the creative process.

So gather a few basic tools, choose some beautiful glass and give yourself permission to simply begin.

Happy creating!
