How did I do that? Fusography >> full-color images on fused glass

This year I will be sharing more about how I do what I do both for those who appreciate fused glass art and others who create it. I am inspired by other artists and hope I may do the same for someone else. I love connecting with anyone who appreciates art so be sure to email or tweet me to let me know if I have inspired you!

It's been a while since I first introduced Fusography and I have been wanting to share some behind-the-scenes photos and information on the process. Creating fused glass pieces with full-color images is a multi-step process that takes about two weeks from start to finish. Of course, the time frame depends on many factors such as the type of piece being created, whether or not glass needs to be ordered and number of pieces being fired.

The easiest way to explain it is step-by-step and include photos. {Be warned that these photographs are horrible. As a professional photographer, I have access to equipment and lighting, but forgot that all my gear was at the studio and not at the house. Ugh!}

Some of the step-by-step will depend on if I am creating pieces to sell or if I am filling a custom order. If it is a custom order I will know what I am creating and the images being used, so the first step would be much easier.

First, I will make some sketches or a list of the types of pieces I want to create. In this case, I was creating a set of four 6 inch square plates to fill a custom order as well as coasters and nightlights, so there wasn't much to sketch, but that would typically be the first step. Part of the first step would also be to determine how many pieces I can create from one sheet of decals. The sheet size is 10 inches by 15 inches and the printer suggests filling the entire sheet. More bang for your buck! To fill the order for the four plates, I had to order to sheets, which meant I had to find some additional images to print.

Blanks ready for decals
Second, edit all of the images {if they haven't already been edited} and put them onto the decal sheet template. My husband does this for me because he is our editor and this is way easier for him than it would be for me. Once the sheets are created they are saved as an image file and eventually uploaded to the printer. The printer has a super easy on-line ordering system including payment so it doesn't take very long once the sheet files are created. The printer fills orders once a week, which can add additional time to an order depending on when it is placed. Orders are submitted by Tuesday, printed on Wednesday and I usually receive the decals on Friday. Planning ahead is key!

One full sheet of decals ready to be cut
Next I will create all of the blanks I need for the pieces receiving a decal. Most Fusography pieces will be white glass because white does not print and if the image has white, it will need to show through. Photos of people will almost always need to have a white blank so teeth and eyes will reproduce normally. Most blanks will be full fused, but some piece, such as nightlights will not have to be fired before the decal is applied.

Kiln full of blanks ready to be fired
One the blanks are fully cooled from the firing, I will clean them and prepare them for decal application. Applying the decals is a bit like cooking. The printer provides complete instructions for getting the decals off the paper and onto the glass. They highly recommend using distilled water in an electric frying pan. I have trouble following directions and use regular water and a regular pan. If you are a glass artist reading this, I would follow the printers instructions.

Heating the water for the decals
Getting the decals off of the paper and onto the glass is a bit of a process and requires patience. I have little patience so this step is very challenging. I go ahead and cut all of the individual decals from the sheet so I don't waste time. The warm water in the pan will evaporate so you need to work quickly. After the decals are cut, I take them, one at a time, and place them in the warm water until the decal curls, then I remove it with chopsticks and being the stressful process of 'sliding' it onto the glass.

Cutting the decals requires patience and good scissors
I recommend heating the piece of glass you are working with using a heat lamp, heat gun or even a hair dryer. Once the decal cools off it becomes stiffer and more difficult to work with. Placing it on a heated surface allows it to stay malleable longer. After you painstakingly slide the decal onto the glass and make sure it is both straight and unwrinkled, you will squeegee the air bubbles out. I use a couple of credit cards for this. Do not apply excessively heavy pressure or you will tear the decal.

Tools for placing the decals on the glass
Customer's images were used to create plates. Decals have been carefully placed.

Decals both on and off coasters
Once your breathing has returned to normal and you have massaged the massive kink out of your neck, it is time to dry all of the decal-covered blanks and prep them for the kiln. I have to apply the decals in my kitchen and then take all the blanks back out to the studio so I use a cool vintage tray to transport the pieces. Avoid stacking the pieces until they have been fired. Just to be safe.

Decals on nightlight blanks
Firing the Fusography pieces is the next stressful step in the process. It's stressful because you have to create a program for the kiln and when I programmed it the very first time I was panicking that it wouldn't work correctly. It did, but I still get nervous. Follow the instructions from the printer and you will be golden. One thing to remember is, the kiln must be vented for what amounts to the first 4 to 6 hours of firing, so make sure you will be near your kiln to close it down at the appropriate temperature.

Kiln is full and ready to begin the 18 hour process
Now, you patiently wait for the decals to be fused to the blanks and pray that you removed all of the air bubbles when you applied the decals. The firing schedule will take about 18 hours to complete. Once the pieces are at room temperature, you can remove them from the kiln and prep them for slumping or draping, if necessary. Fusography pieces can be slumped and draped just like any other fused piece. I have not experienced any crinkling or stretching, but results may vary depending on the piece and mold used.

That is the last step in the process. Each piece can involve up to three firings and additional design and preparation time, which is why these pieces are more expensive than the rest of my fused glass art. And each piece is truly one-of-a-kind. Think of the possibilities! Pendants, rings, earrings, plates, platters, bowls, vases, coasters, business card holders, art panels and more can be created with your own full-color images or any of my available images {soon to be released}.

Thanks for posting. These are great. Where do you get the decals from?

Cheryl Clarke-Hopcroft said...

Very different. Wher do you get the decals and can any printer do the job

Lisa Gifford Mueller said...

The decals can be ordered from In Plain Sight Art at They provide all of the necessary information for preparing your images, ordering and firing.
Good luck!!

Carol Scheydt said...

I have two printers, one is a color printer and one is a just black and white printer. The color obviously has to be printed out on the color printer, but most instructions say to use only black and white. Very confusing.

Thank you for this post -it's very helpful. If you make coasters, do you fuse a clear piece of glass on top to protect the decal once it has been fired onto the blank, or will it hold up ok without it?

Lisa Gifford Mueller said...

Karoline: I don't usually place a layer of clear glass over the decal. They hold up fine without it.

I was actually hoping to just buy some coasters from you but since you have posted such great detailed directions, I am going to try this myself! Thanks!


Lisa Gifford Mueller said...

Let me know how it works out Sydney! Glad I could help!

Thank you for posting this Lisa, you have inspired me to try the process. I will try to let you know how it worked out.

Thanks for the post. Enjoy the monochrome images-looking forward to full color.
Maybe suggest a transfer technique?
(I've used the same technique on Polaroid emulsion lifts in the past)
Use a 8x8 or 13x9 cake pan (depending on size of glass)
Put glass piece in pan, pour water.
Add decal, agitate the pan after a minute gently push a corner away from the paper. Agitate until it floats free.
Remove paper.
Hold down two corners and slowly tilt and pull out of tray.
Smooth out as needed.
Reimmerse in water and repeat to solve and bubble or smoothing issues.

Using decals that permanently fuse to the glass is the main goal of Fusography. Other methods of adhering or transferring images to glass or other substrates are possible, but this is the only way the finished product remains a 100% fused glass piece. There are so many possibilities with the full-color decals!

I am searching for a source for custom decals for glass fusing; simple design, probably script lettering: Jeremy 04/29/2017 Allyson with entwined hearts.

These are for 3" sushi plates that will be of Bullseye Transparent Aquamarine Blue glass. Decal size probably no larger than 1.5" diameter. Decal color- gold.
Quantity: 100 - 150 (depending on the number per sheet)

Could someone please provide information about sources for this type of decal? I would appreciate any guidance you can provide.

Lisa Gifford Mueller said...

Hello! You can order decals from Decal 4 Artists ( That is where I order them from. You can design whatever you wish. Thank you! Lisa

Fawn said...

Lisa, Thank you so much for passing on this tutorial and your decal source. I've been looking for a color alternative to the black/sepia decals I've been printing myself. You have blessed a fellow glass artist more than you know.
~A big Glass Goddess hug for you~
