If you’ve recently acquired 1kg of silicone rubber and are wondering how best to put it to use, you’re in the right place. This page explains the unique crafting and mould making opportunities available with silicone rubber, highlighting your options whether you’re a hobbyist, maker, or creative professional looking for practical or artistic solutions. We compare leading silicone products to help you select the right material for your next project, and provide inspiration for getting the most value from your 1kg batch.

Comparing Your Silicone Rubber Options

One kilogram of silicone rubber opens a world of project possibilities, but each type excels at different applications. Some products are better suited to detailed, translucent moulds, while others are more appropriate for quick, hands-on shapes or industrial-level casts. Differences come down to curing speed, ease of use, compatibility with casting materials (like resin, wax, or plaster), and whether you require a liquid or putty form. Understanding these differences ensures you maximise your silicone for your unique plans.

“Pure Mould” – For Detailed, Translucent Moulds

The “Pure Mould” – Translucent Liquid Silicone Rubber for Mould Making stands out for creators seeking clarity and detail. Its platinum-based formula offers a straightforward 1:1 mixing ratio and fast curing (3–8 hours), with excellent resistance and minimal mould shrinkage. If you plan to use your silicone for repeatable moulds—especially with epoxy resins, polyester, polyurethanes, acrylics, plaster, or cement—this translucent option lets you monitor your pour and ensures long-lasting, reusable results. Its versatility also extends to hot wax casting, making it a favourite for artistic and artisanal projects.

For projects that require capturing every minute feature or intricate undercut, the “Liquid Mould” – Casting Liquid Silicone Rubber, 5-40 Shores, Bi-Component A+B is a bi-component system requiring a catalyst. It’s tailored for producing highly detailed moulds of small objects, complex models, or jewellery, as well as repeated reproductions. With the ability to work with resins, soaps, and polymer pastes, it’s also ideal for creating decorative items, garden art, or technical components. If scale is your focus, look at the “Liquid Mould” – Casting Liquid Silicone Rubber, 15 Shores 20.8 kg for larger volume projects—though for most hobby or small-batch uses, 1kg will go a long way.

• Bi-component liquid silicone rubber requiring addition of catalyst before use

Mix it 1:1 by hand—no gloves needed, thanks to its non-toxic formula—and mould in about 20 minutes. It’s an excellent choice for coasters, miniature trays, or decorative shapes and is particularly suitable if you’re working without a dedicated moulding space or want to avoid the mess of liquid silicones.

• Two-component silicone putty mixed 1:1 for mould creation
• Non-toxic with no smell, safe to use without gloves
• Long working time of approximately 20 minutes (Slow type)
• Non-stick on all surfaces, no need to wash tools or apply release agents

Creative Ways to Use 1kg of Silicone Rubber

With 1kg of silicone rubber, you’re not only limited to a single type of project. Many makers use this quantity to create bespoke jewellery moulds, custom resin art frames, series of functional objects like coasters or drawer knobs, and even intricate decorative elements for furniture or model-making. Small businesses can stretch 1kg across multiple unique moulds for artisanal candles, soaps, or chocolate shapes. The flexibility of both liquid and putty silicone means you can alternate between rigid, high-detail casting and quick, free-form impressions. When trying new projects, always consult the Silicon Rubbers range for product-specific guidance on working and curing times.

Getting the Most from Your Silicone Rubber

Plan your usage by sketching project ideas before you start mixing. Divide your 1kg batch into smaller projects to avoid waste, and always follow the recommended mixing and curing instructions for each product. For inspiration and support, explore our full silicone rubbers range.
