How to: Mosaic Coaster Molds

You can create mosaic patterns on a coaster with the right mold.

The art of mosaic lets you customize items with your own colors and patterns for a look that is yours alone. This includes beverage coasters using tiles, plaster and a mold. The problem with store-bought molds is they only come in certain sizes. The only way to get a larger or smaller mold that fits your needs is to make your own. Making your own mosaic coaster molds takes a minimal amount of time and materials.

Things You'll Need

• Jar lid
• Silicone mold putty

Instructions

1. Clean the jar lid thoroughly. Metal works best because it is sturdy and won't give when pressing the clay into it. However, any jar lid the size you want your coasters will do.

2. Mix equal parts of the two silicone mold putty parts together. The package comes with two different putties; you have to mix them together right before using for them.

3. Press the mixed putty over the outside of the lid. Spread it out evenly using your hands. Cover the entire outside of the lid, including the sides. Allow the putty to dry. To check this, touch the putty because it can look wet even when it's dry.

4. Peel the putty away from the lid once it is dry. It will be in the shape of a coaster; you only need to pour mosaic plaster into it to make coasters. The plaster will not stick to the mold because it is made of silicone, which resists sticking.

Tips & Warnings

• You can use the same jar lid to make another mold. This will help because you can make more than one coaster at a time, which will speed the process.
