Domino is a very popular game that has been around for many years. And how much more enjoyable will it be to play with a homemade set! Thanks to the fact that silicone molds are reusable, you can create an original set not only for yourself but also for those around you. A handmade gift will bring joy to the recipient for many years.

Production process
-
Prepare the mold on a flat, covered surface and use adhesive tape to remove any dust and dirt. Level the surface ideally with a spirit level. If the surface is not perfectly flat, the resin will flow to one side.
-
Mix the required amount of resin and hardener. For one set of dominoes, you need about 200 grams of mixed resin. For dominoes, we most commonly use resin Fluid, Start, and iCrystal.
-
Always mix the resin according to the mixing ratio specified on its packaging and weigh both components on a digital scale with accuracy to the gram. Remember to protect your skin, eyes, and respiratory system from contact with the resin or its fumes during work. Mix both components thoroughly from the bottom and scrape them from the sides of the cup (about 3-4 minutes), then pour the mixed resin into a new cup and repeat the mixing. This eliminates poorly mixed spots that may not cure properly.
-
Either color the entire resin and pour it into the mold, or cast in layers. If you choose to cast in layers, you can leave the first layer uncolored and decorate it with various decorations such as flowers, shells, or other ornaments. After the first layer has hardened, pour the second colored layer and let it harden.
-
Do not delay in processing the mixed resin - the resin is in a higher column in the cup than the recommended maximum pouring height, and therefore the resin works faster and could cure quickly in the cup.
Use only a few drops of color, and for powdered colors, about the amount of two pea-sized balls. Add and mix colors gradually until you achieve the desired shade.
A large amount of color could negatively affect the properties of the resin; the maximum recommended amount of color in the mixed resin is about 2%. -
After pouring into the mold, remove surface bubbles using a lighter. Never hold the flame above the resin for too long; just pass it over the bubbles. If you hold the flame too long on the surface of the mold, the resin could burn to the mold, damaging both the mold and the product.
Remove bubbles at the bottom of the mold, for example, using a toothpick. Also, pay attention to the corners of the molds where bubbles may be trapped. -
Cover the product to prevent dust from falling into it and let it cure. You can cover the mold with a plastic box or place cups around the mold and put a cardboard on top.
-
Color the dots on the dominoes using markers or metallic paints. If you accidentally overpaint the dots, remove the color as soon as possible using a damp cloth.
