How to make resin not stick to mold?
This is one of the rather older techniques that ensures your resin does not stick to your mold, but it also helps to ensure that you do not have any unexpected bubbles form once you pour your resin into your mold. The principle is simple, by ensuring that both your resin and your mold are warm you are ensuring that there’s no difference in surface temperature, which will ensure that no surface tension is created and therefore no bubbles. You should always be careful when you are heating your molds, remember that molds are made of a variety of materials that can react differently to heat, especially depending on the manner in which heat is applied.
How to remove imperfections from resin?
This being said, an easy way to remove imperfections from resin is to simply submerge both the resin and hardener in hot/warm water before you use them . This process is known as degassing which is simply the practice of altering the viscosity of a liquid to ensure that any air present in the normally thick substance rises to the surface in the form of bubbles and they pop!
How are resin bubbles formed?
If you have ever worked with resin, it pretty much goes without saying that seeing these tiny bubbles can be annoying and demoralizing (especially when your project is time-sensitive), but have you ever wondered how these little bubbles are formed? It’s actually pretty simple, bubbles are formed when the surface temperature of a given body of liquid is inconsistent throughout the area it occupies, or when air is being trapped and the surface tension of a given liquid is not enough to collapse these little air pockets. Put simply, the air becoming trapped in the mixture facilitates its presence during the curing process but is still unable to collapse once it has fully cured and/or set. Knowing how these bubbles are formed is all well and good but it doesn’t solve your immediate problem of them existing in your workpiece, so how do you collapse these air bubbles?

Why do resins bubble?
The reason why they escape naturally is that the resin and hardener mixture is thinner, and the bubbles tend to release easier from the surface of the resin. But, it is only for thinner resin mixture, not for thicker resins. Thicker resins are generally used for doming projects, sculpture designing, and furniture. They hold bubbles, especially with thick casting. Doing resins are better suited for thin layers of pours.
What is epoxy resin used for?
It is a type of epoxy glue that is used to protect art, seal jewelry, and fill molds in furniture and sculptures.

What temperature should resin be?
Resins need an ideal room temperature of 70-75 Fahrenheit for curing. Of course, it isn’t convenient for everyone to have heaters running all the time to have the temperature maintained at the perfect rating for resin; so instead, opt for heating a small part of your house like a closet or bathroom perhaps. A portable heater can be more than enough for this purpose. A “Hot Box” is another good suggestion for smaller resin craft; especially if you are looking for casting resin in molds or bezels.
