How long do you sublimate a flask?
If you’re someone who’s looking to personalize your flasks or other metal items, sublimation is a great way to do it. However, getting the sublimation process right can be a bit of a challenge. The good news is, with the right instructions, sublimating a flask in a convection oven can be quite simple.
First, set your oven temperature to 350 degrees Fahrenheit or turbo setting if your oven has it. Once the oven reaches the desired temperature, put the flask in and let it warm up for a minute or two.
Now, it’s time to prepare your flask for sublimation. Make sure the flask is clean and dry, and then place your sublimation design on the rounded side of the flask. Next, use heat tape to tape down the front, top, bottom, and sides of the design to the flask. Be sure to press the tape down well to ensure it’s sealed and that there are no bubbles.
Once you’ve got your design taped down, it’s time to sublimate the flask. Put the flask in the convection oven and set your timer for four minutes.
After the four minutes are up, remove the flask from the oven. Be careful not to touch the hot flask with your bare hands. Now, peel off the sublimation paper while it’s warm but not hot. If the paper sticks to the flask, then it’s too hot, so wait a bit longer before peeling it off.
And there you have it, a beautifully sublimated flask! With these instructions, you can make your own customized flasks in just a few minutes.
Whether you’re making them as gifts or just for yourself, this will be your new favorite simple process. So, grab a flask and get started!
Pro Tip: Remove the top before putting the flask in the oven
Different Baking Times to Sublimate in a Convection Oven
There is no one-size-fits-all approach to sublimation. Different ovens and temperature settings will give different results. Test out a few times and temperature settings to find what works for you.
Can I use my Kitchen Oven?
You can use your kitchen oven but a small convection oven provides even heat distribution and allows for sublimation of the entire flask without the risk of damaging the design.
The small size of the convection oven also means that you’ll use less energy than you would with your large kitchen oven.
