Aluminium pans can be used for dyeing, and some sources claim that they can brighten colours and help shift dyes to new shades. However, it is important to note that salt and vinegar can corrode aluminium, making it more challenging to clean and potentially compromising the clarity of colours in the long term. Additionally, while aluminium can be used as a mordant, it may not be as effective as other options. It is also recommended to avoid using cooking pans for dyeing and to be cautious when using non-food-grade dyes and mordants with food containers.

What You'll Learn
Aluminium brightens colours and can help achieve new shades
Aluminium is a lightweight metal with a silvery-white appearance. It is shiny, reflective, and durable. Its colour can range from bright, shiny silver to matte, dull grey depending on the finishing process applied. This metal is widely used in architecture, combining beauty with functionality. It is used in building facades, roofs, and architectural cladding, where its colour finish enhances the aesthetics of the structure while also helping to reflect sunlight and reduce heat absorption.
Aluminium is also used in dyeing processes, where it is known to brighten colours and help achieve new shades. While some people prefer to use stainless steel dye pots, as they are non-reactive and will not affect the fibres or colours, aluminium pots can offer unique benefits. Aluminium acts as a mordant, helping the dyes fix to the fibres. This property of aluminium allows dyers to achieve deeper and more vibrant colours. For example, Rebecca Desnos mentions in her blog that she has made green dye from fresh spring nettles and the rosiest of pinks from avocados in her aluminium pan, colours she could never replicate in a stainless steel pot.
Jane Mercer, a felt artist, also experimented with dyeing using different types of pans, including aluminium and brass. She found that the same dye process resulted in noticeably different dye bath colours when using aluminium and brass pans. This suggests that the choice of pan material can indeed influence the final dye colour.
It is important to note that using an aluminium pot may not be as effective as using alum (a common mordant) since the action is more random, and some dye particles may be attracted to the sides of the pot rather than the fabric. However, many dyers still prefer aluminium pots because of their brightening effect on colours. Additionally, aluminium is lighter in weight than stainless steel, making it a more convenient option for some.
Overall, aluminium plays a significant role in brightening colours and achieving new shades in the dyeing process. Its reactive nature and mordanting properties contribute to the unique colours that can be produced when using aluminium dye pots.

Salt and vinegar corrode aluminium, making it harder to clean
Aluminium is a popular choice for dyeing fabrics because it brightens colours and can help achieve new and exciting shades. However, it is not the best option for cooking pans due to the risk of corrosion.
Salt and vinegar are known to corrode aluminium, which can make the pan harder to clean. Aluminium is a highly reactive metal that quickly forms a layer of aluminium oxide when exposed to atmospheric oxygen. This oxide layer protects the underlying metal from further corrosion. However, when aluminium comes into contact with vinegar (acetic acid), the acetic acid reacts with the oxidized aluminium atoms on the surface, causing the aluminium atoms to release electrons and resulting in the production of hydrogen gas. This reaction can lead to corrosion and make it more challenging to clean the pan effectively.
The impact of vinegar on aluminium is influenced by factors such as the duration of exposure and the thoroughness of rinsing and cleaning. Allowing vinegar to remain on the surface for extended periods without rinsing can exacerbate the damage and corrosion. Therefore, it is crucial to promptly rinse and clean aluminium pans after using vinegar to prevent further issues.
Similarly, salt can also contribute to corrosion, especially when combined with vinegar. In the presence of salt, the acetic acid in vinegar can accelerate the corrosion process, making it more challenging to restore the pan to its original condition.
To effectively clean aluminium pans, it is recommended to use specialised aluminium cleaners, such as the Star Brite Ultimate Aluminium Cleaner & Restorer. These products are designed to remove stains and restore the aluminium's original appearance. Additionally, Muriatic Acid (hydrochloric acid) is a safe alternative to vinegar for cleaning tarnished or corroded aluminium finishes, as it is not known to cause further damage.

Using aluminium is not as effective as using alum
Aluminium is a reactive metal that can be used for dyeing. It brightens dye colours and can help shift dyes to new shades. For example, green can be made from fresh spring nettles, and avocado dye can be turned into a rosy pink in aluminium dye pots.
However, using an aluminium pot is not as effective as using alum. Alum is a chemical mordant that helps dye fix to fibres. It binds to the fibre, allowing more dye molecules to attach, resulting in more colour. This helps to solve the issue of fading in naturally dyed fibres. Alum also brightens colours.
When using an aluminium pot, some of the dye particles will be attracted to the sides of the pot rather than the fabric, resulting in a weaker effect. While aluminium can still be useful for dyeing, alum is a more effective mordant.
It is important to note that alum may irritate the skin and lungs, so it is recommended to use protective gear such as gloves, a mask, and proper ventilation when working with it. Additionally, keep cookware separate from your dyeing supplies.

Stainless steel is non-reactive and won't affect fibres
Aluminium pans are commonly used for dyeing, and some sources attest to their effectiveness in brightening colours and achieving new and exciting shades. However, stainless steel is also a viable option for dyeing.
Stainless steel is non-reactive, which means it does not react chemically when it comes into contact with other substances. In the context of dyeing, this means that it will not have any effect on the fibres. It will neither mordant nor brighten colours. While stainless steel is generally non-reactive, it may undergo oxidative reactions in certain highly oxidising environments, such as high temperatures and high humidity.
In the field of chemistry, non-reactive materials are considered stable and resistant to chemical reactions with other substances. In the biomedical field, non-reactivity refers to materials that do not react with human tissues or body fluids in a harmful way. Similarly, in the context of cooking, non-reactive materials like stainless steel prevent unwanted chemical reactions between food and cookware, preserving the flavour, safety, and nutritional value of the food.
Stainless steel is widely used in various fields due to its non-reactivity, including food safety, healthcare, and cooking with acidic foods. Its non-reactive properties ensure that no metallic taste or harmful chemicals leach into food, and it provides consistent heat distribution and long-term durability.
In summary, stainless steel is non-reactive and will not affect fibres during the dyeing process. Its non-reactivity makes it a stable and safe option in various applications, including cooking and healthcare.

Iron and copper are reactive metals and will affect the dyeing process
Aluminium pans can be used for dyeing. Aluminium brightens dye colours and can help shift dyes to new shades. For example, green shades can be achieved from fresh nettles, and avocado dye can produce the rosiest of pinks.
Mordants can be thought of as molecular glue, helping the dye adhere to the fabric or fibre. They create a strong bond between the dye and the fibre, making the colour long-lasting and fast to both washing and light exposure.
It is important to note that iron and copper can be used as mordants, but they are not the only options. Aluminium is another mordant that can be used, as well as alum, tin, and soy milk.
