Use alcohol to remove bubbles from resin
Bubbles in resin are a common issue, especially when creating casting in moulds. While torches can be used to remove bubbles, this method can ruin the mould by fusing it to the resin. Therefore, using alcohol is a popular method to remove bubbles from resin.
Firstly, it is important to note that the type of alcohol used is crucial. Isopropyl alcohol is commonly used, and it should be at least 64% alcohol, with some sources recommending 90% or above. The alcohol is usually sprayed onto the resin in a fine mist. This method works well for bubbles that are near the surface. The alcohol breaks the surface tension, causing the bubbles to pop, and it evaporates quickly without leaving any residue or affecting the curing process.
However, it is important to be cautious when using alcohol as it is flammable. It is recommended to avoid using an open flame or torch after using alcohol to remove bubbles. Additionally, using too much alcohol can affect the curing process, making the resin cure bendy or soft. Therefore, it is crucial to allow the alcohol to dry properly before proceeding with any heat treatment.
There are also alternative methods to remove bubbles from resin. One method is to use a pipette or syringe to carefully suck up the bubbles. Another method is to warm the resin before mixing by placing the bottle in warm water for a few minutes. This helps to reduce the formation of bubbles. Additionally, using plastic or silicone sticks for stirring instead of wooden sticks can help reduce bubbles as wood is porous and can introduce bubbles to the mixture.

Use alcohol ink to colour resin
Alcohol inks are ideal for colouring resin because they are alcohol-based. The alcohol evaporates quickly, leaving pigment without disrupting the curing of the epoxy resin. It's important to note that only alcohol-based inks can be used in resin, not water-based ones such as acrylic inks. Water disrupts the epoxy resin curing chemical process.
Alcohol inks offer transparency control, allowing you to easily adjust the vibrancy and saturation of the colour. You can create custom colours by mixing and matching inks until you achieve the desired shade. To achieve an opaque colour, you can add a physical barrier, such as a non-metallic white pigment powder, for the ink to bounce off of and retain its colour.
When using alcohol ink to colour resin, it is recommended to start by pouring the resin into a mold, being careful not to overfill it. Then, add several drops of your chosen alcohol ink colour. You can also create layers of colour by repeating this process, allowing each layer to dry before adding the next.
To enhance the effects of alcohol ink in resin, you can use a heat gun or a blow torch to create a unique, cellular or nebulous appearance. Always follow safety precautions when using these tools. Additionally, you can use a silicone rod to create swirls and soften the edges of ink marks.
It is important to note that the resin in the cup may appear darker than when it is thinly laid down in a mold or painting. Therefore, it is recommended to start with small drops of ink and adjust by adding more drops as needed.

Use alcohol to preserve specimens before casting
When using alcohol to preserve specimens before casting in resin, there are several important steps to follow. Firstly, it is crucial to understand that not all types of alcohol are suitable for preservation. While isopropyl alcohol can be used for storage, it is not a fixative and will not prevent the specimen from decomposing. Formalin or ethanol preservation is recommended to truly fix the specimen and prevent rotting.
The first step in preserving a specimen is to inject the fixative throughout the entire specimen—through the mouth, ears, eyeballs (if the eyes are closed), body cavity, anus, and large muscles. The goal is to ensure that the fixative penetrates as much of the specimen as possible, including under the skin. For larger specimens with hair, making tiny incisions in the skin can help the fixative soak in.
Once the specimen is injected with the fixative, it should be placed in a large jar in the desired display position. The container must be made of glass or, if plastic is used, it must be ensured that it will not chemically react with the preserving fluid. The jar should then be filled with the same fixative used to inject the specimen, and it must be sealed. Most fixatives will cause the tissues to harden.
After the initial preservation, the specimen can be transferred to a secondary solution of diluted isopropyl or ethanol alcohol for long-term storage. This step is crucial, as isopropyl alcohol is not strong enough to fix the specimen but can help delay decomposition. The preferred percentage of alcohol for storage is 70%, as higher concentrations can cause tissue shrinkage in certain specimens.
It is important to note that proper care and storage of preserved specimens are essential. They should be kept away from heat sources and direct sunlight, as the chemicals used are highly flammable. Additionally, the jars should be securely sealed to prevent curious individuals from opening them. With the right preservation techniques and careful storage, specimens can be effectively preserved in alcohol before being cast in resin.

Use alcohol to dilute resin
When working with resin, it is important to clean your prints thoroughly. Resin prints are known for their delicacy and detail, and cleaning them with the correct solvent is critical to achieving the best results. Uncured resin left on the surface can be removed by soaking the print in alcohol. This process improves the visibility of details on the model to ensure the final print's cleanliness and accuracy.
There are several types of alcohol that can be used to clean resin. Isopropyl alcohol (IPA) and ethanol are commonly used to clean resin prints. Denatured alcohol is also effective at dissolving uncured liquid resin. When using IPA, it is recommended to use a concentration of 95% or higher. Commonly used concentrations include 70%, 91%, and 99%. Lower concentrations, such as 70% IPA, are suitable for general cleaning, while higher concentrations like 91% or 99% IPA are better for thorough cleaning and effectively removing resin debris.
To clean a resin print, pour the alcohol into a container large enough to completely submerge the print. Allow the print to soak for a few minutes, depending on the concentration of alcohol and the degree of cleaning required. It is important to wear personal protective equipment, work in a well-ventilated area, and avoid inhaling alcohol vapors during this process.
In addition to cleaning, alcohol can also be used to reduce bubbles in resin. A small amount of alcohol can be added to the resin before pouring it into the mold to help eliminate bubbles. However, too much alcohol can prevent the resin from curing properly. A light spray of alcohol on the surface of the resin can also be used to break surface bubbles.

Use alcohol to create a marbled effect in resin
Creating a marbled effect in resin using alcohol is an easy process, but it requires some preparation. Firstly, you should prepare your surface by covering your worktable with freezer paper. This will ensure that your work area stays clean.
Next, you should prepare your resin. You can use a variety of resins for this process, such as polyurethane resin or epoxy resin. If you are using epoxy resin, you will need to mix equal parts of resin and hardener by volume to create an epoxy resin mixture. If you are using polyurethane resin, you can add a thickener to gain more control over the marble pattern. You should also prepare your mould by properly releasing it before pouring the casting resin.
Once your resin and mould are ready, you can start creating the marbled effect. One method is to mix three separate alcohol ink colours in a full mould of resin. You can add 3-4 drops of each colour, trying not to overlap them directly, and then watch the colours spread out and mingle. You can also add alcohol ink to the resin before pouring it into the mould. The drops will sink into the epoxy, and the colours will naturally blend to create a unique marbled look. Another method is to apply a thin layer of alcohol blending solution to your object using a regular paintbrush, and then use fine paintbrushes to apply alcohol inks in various wavy lines. You can then use a small paintbrush dipped in rubbing alcohol to gently pat the alcohol ink lines and spread the colour to create a marbled effect.
Finally, you can add some additional touches to your creation. For example, you can add gold accents by using crafting glue to apply gold flakes or painting on gold alcohol ink. You can also add glitter to your resin mixture to create a show-stopping effect. Once you are happy with your creation, allow it to cure and sand down any uneven areas before applying a final coat of epoxy resin.
