Getting a flawless, bubble-free finish when making resin Christmas baubles can be challenging for both beginners and experienced crafters. However, with a few simple techniques, you can easily reduce or eliminate bubbles for a professional look.
Understanding Why Bubbles Form
Bubbles are a common occurrence when working with resin, especially in detailed or closed moulds like baubles. They usually form due to vigorous mixing, rapid pouring, or trapped air around embellishments. Choosing a resin with enhanced degassing properties, such as those found in the Evershine Collection Artisan Jewellery Epoxy Resin Kit, can make a difference, particularly when working with delicate inclusions or fine details.
Mixing and Pouring Techniques
To minimise bubbles, mix your resin slowly and steadily. Quickly stirring or beating can introduce unnecessary air. Scrape the sides and bottom of your mixing cup to ensure all resin and hardener are incorporated, but be gentle. When pouring into moulds, try to pour in a slow, thin stream. If adding decorations like glitter or small ornaments, press them gently into the resin to avoid further air entrapment.
Removing Bubbles Before Curing
After pouring, it’s normal to see small surface bubbles. You can remove them by applying gentle heat: pass a heat gun or small torch briefly over the resin surface, being careful not to overheat. Alternatively, a pin or cocktail stick can be used to pop stubborn bubbles, especially around detailed areas. For UV resin projects, ensure your workspace is dust-free, as dust can trap bubbles that are harder to remove once cured.
When Bubble Prevention Matters Most
If you’re creating baubles as gifts or for sale, a crystal-clear finish is essential. Bubbles can also interfere with the clarity of embedded decorations, so taking time with these steps is well worth the effort.
