Silicone vs. Metal: The Best Candle Molds for DIY Projects

Making candles is a craft that has won over do-it-yourselfers all around the world. The correct mould is essential to getting the ideal outcome whether you're creating candles as a hobby, a side gig, or just as presents. Silicone and metal moulds are two of the most widely used mould types for do-it-yourself candle making, and each has certain advantages and traits. To assist you in selecting the ideal silicone or metal candle mould for your projects, we will examine the advantages and disadvantages of each in this blog.

Silicone Candle Molds

Making candles is only one of the numerous areas where silicone has become the preferred material for do-it-yourself artisans. These moulds are renowned for producing complex, detailed designs and for being flexible and simple to use. Here’s a closer look at the key features of silicone candle molds:

Pros of Silicone Candle Molds

1. Flexibility and Ease of Release The flexibility of silicone moulds is one of its greatest benefits since it makes removing the completed candle from the mould considerably simpler. Even for intricately detailed designs, the mould can be gently peeled away from the candle because to the soft, elastic material. This lessens the possibility that the candle will break or get damaged while being unmolded.
2. Non-stick Surface Because silicone moulds are inherently non-stick, your candles won't stick to them. This feature makes it easier to release candles and reduces the need for any additional oils or wax releases. As a result, silicone molds are incredibly user-friendly, especially for beginners.
3. Versatility in Design Silicone molds are generally available in a variety of shapes and sizes, ranging from basic geometric forms to more complicated, intricate patterns, such as flowers, animals, or even ornamental patterns. Silicone moulds let you try out countless creative options, whether you're looking for a sleek, contemporary pillar or a quirky candle in the shape of a flower.
4. Durability Premium silicone moulds are strong and resistant to deterioration when exposed to the heat of melted wax. They can endure for numerous candle-making operations because they are also resilient to deterioration. You can keep utilising silicone moulds without worrying about them deteriorating because they are frequently reusable.
5. Temperature Resistance A large range of temperatures can be tolerated by silicone moulds. Because of this, they can be used with a variety of wax kinds, such as paraffin, beeswax, and soy wax, which may have varying melting points. Silicone is able to manage the heat and coolness of wax.

Cons of Silicone Candle Molds

1. Not Ideal for Perfectly Smooth Edges Even while silicone moulds may produce incredibly intricate shapes, you might not always get a flawlessly smooth edge finish. Silicone moulds might not be the greatest option if you want a candle with crisp, sharp edges.
2. May Be Too Flexible for Some Designs When making particularly tall or thin candles, silicone moulds may not always be as sturdy because of their flexibility. When the wax is cooling, the mould may move a little, changing the shape of the candle if you want to make a tall, huge one.

Metal Candle Molds

Conversely, metal moulds have long been a mainstay in candlemaking. Metal moulds, which are typically constructed of stainless steel, tin, or aluminium, have a number of advantages that appeal to do-it-yourself craftsmen seeking crisp edges, a glossy finish, a shiny finish, and precision. Here's what you need to know about metal candle molds:

Pros of Metal Candle Molds

1. Crisp, Clean Edges For candles with distinct, sharp edges, metal moulds are ideal. Metal moulds can provide consistent, straight edges without the small bending that silicone moulds may cause, which is ideal if you're going for a polished, streamlined appearance. They are therefore perfect for creating traditional pillar candles, tapers, or any other type of candle that needs to be precisely shaped.
2. Sturdiness Because metal moulds are frequently stiff, they hold their shape well and offer superior support for taller candles. Large or heavy candles work especially well with metal moulds because of their stiffness, which prevents the mould from bending or flexing when the wax cools.
3. Smooth Finish Metal moulds tend to give candles a sleek, glossy finish because of their polished, flat surface. This is particularly useful when creating candles that need to have a glossy appearance. A metal mould can help you attain that flawless, smooth surface whether you're using metallic wax or attempting to make a high-end, sophisticated candle.
4. Excellent for Multiple Candle Pours Metal moulds are capable of withstanding several candle pours without losing their structural integrity. Because the wax will cool evenly and without distortion in the mould, they are excellent for producing several candles at once.

Cons of Metal Candle Molds

1. Difficulty in Release The fact that metal moulds are more difficult to unmold than silicone is one of their main disadvantages. Candles may adhere to the sides because to the stiff surface, particularly if no lubricant or release agent is used. You might need to tap the mould or wait for the candle to cool fully before removing it carefully.
2. Prone to Scratching and Dents Even though metal moulds are strong, they may eventually be more vulnerable to wear, dents, and scratches, particularly if you use them regularly. These flaws may accelerate the deterioration of your moulds and have an impact on the look of your candles.
3. Less Flexibility in Design In general, silicone moulds offer more complex patterns than metal moulds. They can be used to create pillar candles or basic geometric shapes, but they might not offer as many different designs (such as flowers or animals) as silicone moulds. If you're prepared to spend a little extra, you can get moulds specifically designed for particular shapes and styles.
4. Heavier and Bulkier Metal moulds can be more difficult to handle, particularly for big moulds, because they are frequently heavier and bulkier than silicone. Metal moulds may be more challenging to handle and pour wax into if you intend to create huge candles.

Which Mold Is Best for Your DIY Candle Projects?

The type of candles you wish to make and your own preferences as a craftsman will ultimately determine which candle mould is best for your do-it-yourself projects. Here's a brief synopsis to aid with your decision:
