Resin is a natural or synthetic compound which begins in a highly viscous state and hardens with treatment. Typically, resin is soluble in alcohol, but not in water. There are a number of different classes of resin, depending on exact chemical composition and potential uses. There are numerous applications for resins, ranging from art to polymer production, and many consumers interact with products which contain resin on a daily basis.
Natural resin comes from plants. A classic example is pine sap, which has the characteristic sharp odor of terpene compounds. As anyone who has interacted with pine sap knows, the substance is very viscous, but it hardens over time. A number of other plants produce resins, and plant resins have been used by humans for thousands of years. Some plants exude a similar substance called gum or gum resin which does interact with water. Gum tends to be softer and more malleable than resin.

The Basics of Resin Casting
As the name suggests, resin casting is a casting process that involves the use of synthetic resin. To better understand how it works, you must first look at the synthetic resin used in this casting process. Synthetic resin is any type of resin that’s converted into strong and rigid polymers via curing. In other words, it begins in a liquid state but converts to a solid state after being cured.
In resin casting, liquid synthetic resin is mixed with a curing agent — typically at room temperature or near-room temperature. Next, the two substances are poured into a mold cavity. The curing agent then converts the resin into rigid polymers, essentially hardening it. After this chemical reaction has finished, the hardened casting is ejected and removed from the mold cavity.
Advantages of Resin Casting
Resin casting is a simple process that can be performed using just a few basic tools and materials. In fact, many hobbyists use resin casting to create small objects. It’s a simple and low-cost way to produce small objects, making it a popular choice among individuals and hobbyists for leisure purposes.
Resin casting is also capable of producing objects in complex shapes. The shape of the casting is dependent upon the shape of the mold cavity. By using the right type of mold cavity, a manufacturing company — or a hobbyist — can create a casting in their desired shape.
Disadvantages of Resin Casting
On the other hand, resin casting is a poor choice for manufacturing companies looking to mass-produce a large quantity of objects or products. For starters, the synthetic resin used in this casting process is highly aggressive when exposed to a curing agent. As a result, molds typically only last for 50 to 100 uses, after which the mold must be discarded and replaced with a new mold.
Additionally, there are health concerns regarding the use of synthetic resin. During the curing stage, synthetic resins may release toxic and harmful fumes.

Resin is gum type materials of the pine tree. This can extract from pine tree through different methods. Rosin is that which is made from resin. When the resin will be melted and make separation. Then rosin and turpentine oil will made from rosin. Resin cannot made from rosin, its directly extract from pine tree.
I just paid $250 for a resin inlay in South Korea.
Ion exchange resin is used in separation, purifying and decontamination processes. The resin is an insoluble matrix. They are usually made of cross-linked polystyrene molecules.

Resin casting is done by use of a mold and a mixture made with a form of liquid synthetic resin. It is then poured or injected into the mold and left to sit until hardened.
Two popular types of casting include: metal casting and concrete casting. However, there's also resin casting as well as iron casting.
I am just getting started in casting with Resin and looking up suggestions and ideas before getting started so I am familiar with what I am dealing with. KM from Virginia
When one casts resin, they are using a different form of the word than in acting. 'Cast' in this case refers to a mold. Resin is a type of plastic, and casts are made by pouring hot melted plastic into a mold to produce a shape.

You do not want to use a glass mold when casting resin. Resin is a two-part compound that, when mixed in proper proportions, becomes completely hard when dry. When casting resin, you want to use a flexible mold, such as a silicone mold, to cast it. Once the resin has hardened, you can flex a silicone or rubber mold, stretching and bending it to allow air between the mold and the shape, which allows the mold to release the resin form. The mold will revert back to its original state after the form has been released. A glass mold has no flexibility. If you cast resin in a glass mold, the resin will harden exactly the size of the cavity in your glass mold. While it will not bond to the glass, the result is the same. Once the resin is hard, there will be no way for air to come between the resin form and the glass mold. The resin will essentially be vacuum-sealed in place. If you have a more complex form, such as a rose shape, the resin will be stuck in place permanently. A more simple shape, such as a square, might release over time. If you set the mold upside-down, a combination of gravity, and the effects of temperature and humidity on the glass and resin, may release the resin after many weeks or months. If you have already cast your resin into the glass mold, your only option will be to wait to see if the cast will eventually release, or carefully break the glass mold from around the resin.

I know Michaels www.michaels.com, carries mold making materials and casting resins, hobby lobby www.hobbbylobby.com, may also carry the same things.
With that same resin's liquid resin.
Using wax to make a casting of something in a mold and there is something called lost wax casting where you model something in wax, pour plaster around it to form a mold, melt the wax out and cast it in metal or resin.
