How to make molds for epoxy resin from starch and sealant
Epoxy resin is a liquid two-component composition. To make a cabochon, it is poured into molds. But you don't have to buy them at all. You can create a silicone mold yourself.
To work you will need:
4. Sprinkle 3-4 tbsp on top. l. corn or potato starch.
5. Begin to gently knead this mixture like dough.
6. You need to do this until the silicone stops sticking to your hands. Add starch if necessary. It is impossible to calculate the exact proportions of the ingredients; it all depends on the quality and quantity of the components used and the temperature in the room.
7. When the mixture begins to roll into a ball, tear off a piece of it.
8. Form an oval and press the selected workpiece into it. It can be a pebble made of acrylic, glass or plastic.
9.Leave the mold to set for 24 hours.
Keep in mind that the sealant has an unpleasant vinegar aroma, so ventilate the area well. Be sure to protect your hands with gloves. The process of creating a mold will seem familiar to those who know how to knead dough.
The shape of the blank can be any from a sphere to a cameo and buttons. This mixture perfectly imprints edges and small details. But if you are using glass, then lubricate the element with Vaseline. Do not press the cabochon deeply, otherwise nicks and cracks will form along the edges.
Advantages of this method:
Molds made from starch and sealant are durable and suitable for various types of creativity.
To work you will need:
- gloves;
- acrylic blanks;
- starch;
- sealant.
