Frequently asked questions about Glass Fusing Decals!  If you have a question that isn’t covered here, please contact Michelle at info@glassfusingdecals.com and she will be happy to help you out.

What type of glass can Glass Fusing Decals be used on?

Our decals can be used on any glass surface, including glazed ceramics!
COE 90, 96 and 104 are the most common, but the only real criteria is that the glass or ceramics you are using can withstand the required firing temperatures for the decals.  If they can, you’ll get beautiful crisp, clean decals every time.

What is the difference between High-Fire and Low-Fire decals?

High-Fire decals fire at a temperature of about 1420ºF, whereas Low-Fire decals fire at a temperature of about 1100ºF.  Each temperature range has it’s own uses:

High-Fire decals might be used on smaller projects that have been cold-worked and need to go back in the kiln to be fire polished.  This is ideal as you can fire out the decal and fire polish all in one firing.

Low-Fire decals are ideal for work that needs the decal, but you don’t want it to lose it’s shape in the firing. Items such as plates, bowls, vases or other more dimensional work would be best with a Low-Fire decal because the firing temperature is low enough that the glass won’t lose its shape.

Whichever you use, the firing schedules for both types of decals are below full fuse temperatures, which means you can use the one that best suits your project.

Do you offer colours other than black and white?

Absolutely!  We’ve found black and white to be the most useful and popular colours for decals, so these are part of our initial line, however, we can definitely provide decals in any colour including silver and gold. Generally, white and gold decals will be high fire as they require a higher temp to fuse properly, but we are happy to take requests and provide quotes to suit your needs.

Can I fire the decals between two layers and ‘cap’ them? 

Technically, yes, you could, but if you want perfect clean results the decals should be your LAST firing and go onto your finished piece. You are always encouraged to experiment with new ways to combine glass working techniques and inclusions, but if you attempt to case decals in between layers of glass, the finer lines are likely to break apart creating a more worn-out, antique look.  If you plan to attempt this, you must use the high-fire decals, and  properly fire your decal onto the bottom layer of glass first. Then you can do a second firing to cap it with the second layer.  If you attempt to do this all in one step, you will end up with a mess as the decal medium may not have enough air space or heat to burn off properly and will likely create an air bubble in the piece, as well as ruining your decal.

The decals rubbed off, what happened?

If your decals rub off or blow away like powder after firing, they have not been fired long enough! Check your kiln settings to see if your kiln is going to a high enough temperature for the decals you are using.  Our main line of decals is considered to be high fire, and requires temperatures around 1420F to properly fuse to the glass.

Why did I get blisters or cracks in my decal?

It is most likely that you over-fired your decals or held your hold time too long.

Why did I get “pinholes” in my decals after firing?

In this case, you probably didn’t get all the air bubbles out of the decals before firing. Be sure to take a paper towel and gently, but thoroughly, squeeze any excess water off the decal when applying. If you see any air bubbles at this point, use your damp paper towel or cloth and push them from the middle of the decal out toward the edges until they are all gone, then allow them to dry for 24 hours before firing.

Can I get online help?

You bet! Michelle has over 10 years of kiln glass experience and is here to help you achieve the best results you can! You can email her at info@glassfusingdecals.com as much as you need!

Do you sell wholesale?

Yes we do! Please contact Michelle with your wholesale inquiries and she will be happy to give you quotes and more information.

How do you ship the decals?

I ship the decals in their own separate pouches with protective waxed paper, all in a CD-sized rigid mailer via regular post.  This keeps the cost of shipping down around $2.50, whereas the next option up  is around $20 (I felt this was ridiculous for any number of decals).  This means there is no tracking number, and the decals may take between 7-15 days to arrive depending on your location within North America with respect to Toronto, Ontario in Canada where we are located.   If you would prefer trackable shipping, or a rush order, please contact us before you make your purchase to make arrangements for that.

Thank you everyone for your support!
