Silicone Putty vs Liquid Silicone: Best for Beginners?

Q: Silicone Putty: The Quick and Simple Route

For many beginners, silicone putty—such as I–Gum —is the most straightforward option. Simply mix equal parts by hand, press the putty directly onto your object, and wait a short time (typically 20–40 minutes) for it to cure. There’s usually no need for special tools, release agents, or precision pouring, which makes it a low-fuss way to capture basic shapes. Non-toxic, with minimal odour, it’s ideal for smaller objects, jewellery, or creative crafts where convenience is a priority.

Q: Liquid Silicone: Flexibility and Finer Detail

Liquid silicone, such as Pure Mould , offers greater flexibility for more complex shapes and finer details. However, it does require careful mixing, pouring into a prepared mould box, and a longer curing time (several hours). Beginners willing to take on a little extra setup can achieve highly detailed, reusable moulds suitable for resin, wax, or even soap casting. This method is often preferred for larger or more intricate projects once you’re ready to advance your skills.

Q: When to Choose Each Type

Choose putty when you want speed, simplicity, and direct moulding—perfect for one-off crafts, small items, or fast experiments. Choose liquid silicone if you need detailed, professional results or plan to reproduce an object many times.
