I have tried sublimating glass with a sublimation coating i bought which works well on ceramic mugs but when i put in the oven they cracked what am i doing wrong please?
Sublimating onto glass can indeed be a bit tricky, especially when it comes to managing temperature and materials.
Common Reasons for Glass Cracking During Sublimation
Incompatible Glass Type
Not all glass types are suitable for sublimation. Ensure that you're using glass that's designed to withstand high temperatures.
Rapid Temperature Changes
Glass is sensitive to quick changes in temperature. Preheat your oven to the desired temperature before placing the glass inside, and allow it to cool gradually rather than removing it immediately from the oven.
Uneven Heating
Ensure that the heat is distributed evenly in the oven. Consider using an oven thermometer to check whether the temperature is consistent throughout.
Incorrect Sublimation Coating
Some sublimation coatings may not adhere well to glass, even if they work on ceramics. Make sure your coating is specifically designed for use on glass.
Incorrect Pressure or Positioning
Check if the pressure is too high or if the positioning isn’t ideal in the oven, which can cause stress on the glass.
Tips for Successful Glass Sublimation
Properly Prepare the Surface
Ensure the glass is clean, dry, and free from oils or dust before applying any sublimation coating.
Gradual Temperature Changes
Begin with a lower temperature and then increase it gradually to the desired setting to minimize the risk of cracking.
Test Different Coatings
Try testing small pieces first with different coatings to see which works best before committing to a larger project.
With some adjustments, you should find the sweet spot for sublimating onto glass. Happy crafting! 😊

Considerations for Using Sealants
Ensure that your sealant is compatible with the specific materials you're using. Test it on a small area first to avoid any unwanted reactions.
While specific experiences with Magic Seal can vary, many crafters find sealants helpful in preserving their projects. It's always exciting to see how different crafters achieve their desired results!
What product works best for coloring etched glass? I have acrylic markers but they don't fill in large areas well. The larger areas become streaky.
Coloring etched glass can be a magical way to add a pop of color and vibrancy to your finished project.
Best Products for Coloring Etched Glass
Glass Paints
Using glass paints is an excellent option for coloring etched glass. They are specifically formulated to adhere to glass surfaces and provide a smooth, vibrant finish. Brands like Pebeo and Vitrea 160 offer paints that can be air-dried or baked for increased durability.
Alcohol Inks
Alcohol inks are another wonderful choice, as they provide rich, fluid colors that spread evenly. Applying them with a felt pad or a brush can help in achieving even coverage, even on larger areas.
Oil-Based Paint Pens
Unlike acrylic pens, oil-based paint pens offer a more consistent finish on glass surfaces. They are designed to be permanent and have better opacity, reducing streakiness for larger areas.
Experimenting with these options can help you achieve the perfect look for your etched glass projects. Remember to always test on a small area first. Happy crafting! 🎨✨
