Quick and Easy Molds for Miniature Projects

Two-part silicone mold putty can be used to make simple flexible molds to cast parts for dollhouse and model scale miniatures. Two-part silicone putty allows casting of a variety of materials, from polymer clay, gesso, and plaster to resin and metals. Silicone putty molds withstand reasonable heat. There are food safe forms available if you want to turn your miniature fido into special chocolates using silicone molds!

    How to Use Two-Part Silicon Mold Putty

    Two types of clay ready for making molds.

     Lesley Shepherd

    Two-part silicone mold putty is the fastest way to make detailed casting molds of miniature parts. It is often used for repeating items made from polymer clay or various casting metals. Molds made from the putty will last for many years and take only a few minutes to make. Easy and safe to use it is available with a variety of setting times and heat tolerances. Molds for food products can be made from food-safe forms of the putty.

    The only downside of two-part silicone mold putty is that it works best for simple press molds. It can be used for full molds if you wrap the object to be molded carefully, making sure the thickness of the material does not shift as it is wrapped over the master.

    Mold details for furniture and accessories for dolls houses, railways or gaming terrains using gesso, resin, plaster, or polymer clay and simple molds made from two-part silicone mold putty.

    Decorative Moldings cast this way in a simple one part mold are an asset when trying to copy carved antique furniture styles, mirror frames, or stone swags and pediments on model buildings.

    Molds allow you to reproduce your specialized pieces over and over again to decorate sets of items (including miniature furniture) and silicone putty molds stand up well to reuse.

    This project shows you how to use two part silicone mold putty to make simple one part plunge molds used to make polymer clay muffins, cupcakes, and fairy cakes in miniature scales. You may not need miniature muffins, but there are lots of other miniature parts you can cast this way in similar molds for gaming scenes, vehicle models, railroad scenes and dollhouses. These plunge molds work well for items with straight sides, or which are narrower at the bottom than at the top.

    Make a Simple Mold for Pie Shells

    When you need a two-sided mold of an object to give you details all around, push molds are often a good solution. Push molds allow you to squash a malleable material (polymer clay, clay, paper clay) between the two layers and then remove your cast.

    This simple pie crust push mold allows you to make scale miniature pie crusts from polymer clay. The molds are based on a metal bottle cap for dolls house scale, or an original pie crust sculpt in polymer clay for other scales. Flexible push molds like this one aren't useful for all items. They work best for projects with simple details and few undercuts.

    Two-sided push molds for polymer clay can also be made from plaster with the instructions given here for simple plaster push molds.
