Making glycerin soap at home is a fun and fulfilling DIY activity. It is important to use the right materials when making soap, as some metals like aluminum react with lye and ruin the pan and the soap. Stainless steel, silicone, and teflon are suitable alternatives. Glass and plastic bowls can also be used, but it is important to note that glass may require extra preparation for easier release. Glycerin soap recipes typically involve melting oils and fats, combining them with a lye-water mixture, and adding alcohol and glycerin before pouring the mixture into molds to solidify.

What You'll Learn
Stainless steel is safe to use, but not aluminium
When making glycerin soap, it's important to choose the right materials to mix and mould your soap. While stainless steel is safe to use, aluminium is not.
Aluminium and lye do not mix. Lye is a crucial ingredient in soap-making, and it will react with aluminium, causing the metal to fizz, decay, and corrode. This will ruin your pan and your soap. The aluminium will react with the lye, turning black and destroying the soap. Even coated aluminium is not safe to use, as the lye can eat through the coating and start corroding the metal underneath.
On the other hand, stainless steel is a suitable material for making glycerin soap. It is compatible with lye and will not react or corrode when used with this ingredient. You can safely use stainless steel pots and pans to mix your lye and water solution and heat your fats and oils.
However, it's important to note that metal soap moulds can be challenging to work with. Metal moulds, regardless of the type of metal, can make it difficult to unmold the soap due to their rigidity. It is recommended to use flexible moulds or line your moulds with materials like silicone, Teflon, or plastic to make it easier to release the soap.
In summary, when making glycerin soap, stainless steel is a safe option for mixing and heating your ingredients, but it may not be ideal for moulding. Avoid using aluminium at all costs, as it will react with the lye and ruin your soap and your pan. Always prioritise materials that are compatible with lye and will not contaminate your soap or compromise your safety.

Lye and water should be mixed in a stainless steel pot
It is generally advised to mix lye and water in a stainless steel pot. Lye does not react to stainless steel, and stainless steel is not susceptible to etching or shattering from exposure to lye, unlike glass. Stainless steel is also preferable to plastic, as it is sturdier and can withstand higher temperatures.
When making soap, it is important to be cautious with material compatibility, especially when working with lye. Lye can corrode certain metals, such as aluminium, and render them unusable. It can also cause etching in glass, leading to dangerous shattering. Therefore, it is recommended to use stainless steel pots or HDPE containers for mixing lye and water.
While stainless steel is a suitable material for mixing lye and water, it is important to ensure that the stainless steel pot is not a blend of stainless steel and aluminium. Pure stainless steel does not react with lye, but aluminium will fizz and decay when exposed to lye, ruining both the pot and the soap batch.
Additionally, it is worth noting that while plastic containers can be used for mixing lye and water, they should be checked for heat resistance. Look for the recycle triangle on the bottom of the container; PP #5 is resistant to alkali and can withstand boiling water, while HDPE #2 is safe up to 190°F.
In summary, when making glycerin soap or any soap involving the use of lye, it is recommended to mix lye and water in a stainless steel pot to ensure safety, durability, and compatibility with the chemicals involved in the soap-making process.

Fats and oils can be heated in a separate metal pot
Making glycerin soap at home can be a fun and fulfilling DIY activity. To make glycerin soap, you can use a homemade glycerin base or melt-and-pour glycerin-based bars. When preparing the soap, it is important to consider the type of materials that can be used. While metal pans can be used, it is important to avoid certain types of metals.
When making glycerin soap, it is essential to follow specific steps to ensure the desired outcome. After heating the fats and oils in a separate stainless steel pot, they can be combined with the lye solution. This mixture is then cooked on low heat for several hours until it reaches a thick, gel-like consistency. Alcohol and glycerin are then added to the mixture, which is blended until it becomes smooth and uniform in colour and texture.
The process of making glycerin soap involves precise measurements and techniques. It is important to weigh out the ingredients accurately, including the fats, oils, and glycerin. The use of kitchen scales can ensure that the correct amounts of beef tallow, coconut oil, castor oil, alcohol, and glycerin are used. Additionally, when preparing the soap, it is recommended to use a slow cooker or a microwave-safe bowl for melting the ingredients and a stainless steel spoon for mixing.
By following these steps and using the appropriate materials, such as stainless steel pots for heating fats and oils, you can successfully create glycerin soap at home. It is important to be cautious and informed about the materials used in the soap-making process to avoid any unwanted reactions or contamination. With the right tools and ingredients, making glycerin soap can be a rewarding and enjoyable experience.

Glycerin soap is translucent and can be customised
Glycerin soap is a fun and fulfilling DIY activity that anyone can master. It is perfect for those with sensitive skin as it gently cleanses and moisturises the skin.
Glycerin soap is often translucent, and its clarity can be controlled by the level of alcohol and water in the mixture. The higher the alcohol level and the lower the water level, the clearer the product. Glycerin soap can also be customised by adding certain solvents like sugar, alcohol, and more glycerin. These solvents help make the soap crystals small so that light can pass through, giving the soap its translucent appearance.
To make glycerin soap, you will need a microwave-safe bowl, a skin-safe essential oil of your choice, and a mould. You can melt one block of glycerin-based melt-and-pour in the microwave in 30-second intervals. Once the soap is completely melted, add your chosen essential oil, then pour the mixture into your moulds and let it solidify for 24-48 hours.
It is important to note that when making glycerin soap, you should avoid using aluminium pots or pans as they can react with the lye and ruin your soap. Stainless steel, silicone, Teflon, and HDPE plastic are recommended materials for soap-making.

Glycerin soap is made by adding glycerin to regular soap
Glycerin soap is a great option for people with sensitive skin as it helps lock in the skin's natural moisture and prevents over-drying. It is derived from plant-based oils and is water-soluble, clear, and naturally fragrance-free.
Glycerin is a byproduct of the soap-making process, and all soap contains glycerin to some extent. However, glycerin soap is made by adding more glycerin to regular soap. The additional glycerin is cooked with solvents like sugar, alcohol, and more glycerin to make the soap crystals smaller, allowing light to pass through and giving the soap a translucent appearance.
To make glycerin soap, you can use a slow cooker to combine the soap base with glycerin and other ingredients. First, measure water into a heat-proof container and slowly add lye, stirring until dissolved. Allow the lye water to cool to 150°F. Then, mix all the oils together and heat to 135°F. Add the lye water to the oils slowly and blend until it reaches a pudding-like consistency. At this point, you can add more ingredients like essential oils, dried herbs, or food coloring.
Once you are happy with the mixture, pour it into molds and let it solidify for 24-48 hours. Remove the soap from the molds, wrap them in wax paper, and store them in a cool, dry place. You can also get creative with the molds by using a length of string dipped into the liquid soap and allowing it to harden, creating soap on a rope.
