Understanding Spectrum Underglaze

Before we dive into the recipe, let’s briefly discuss what spectrum underglaze is and its significance in pottery.

Spectrum underglazes are essentially colored slips or pigments that are applied to greenware or bisqueware before the final glaze firing. They provide a wide range of vibrant colors and can be used for detailed designs, intricate patterns, or overall coverage on ceramic pieces. Spectrum underglazes are versatile and can be applied in various ways, including brushing, dipping, spraying, or sgraffito techniques.


Ingredients and Materials

To create spectrum underglaze, you’ll need the following ingredients and materials:

  1. Raw Materials:
    • Frit (Feldspathic)
    • Kaolin
    • Silica
    • Various metal oxides (depending on desired color)
  2. Tools and Equipment:
    • Digital scale
    • Mixing bowls
    • Ball mill or mortar and pestle
    • Sieve
    • Spatula or scraper
    • Measuring spoons
    • Safety gear (gloves, mask, goggles)

Step-by-Step Guide to Making Spectrum Underglaze

Now, let’s proceed with the detailed instructions for making spectrum underglaze:

Step 1: Weighing Raw Materials

  • Set up your workspace with all necessary tools and equipment.
  • Using a digital scale, measure out the required amounts of frit, kaolin, silica, and metal oxides according to your desired color recipe. Be precise in your measurements to ensure consistency in the final product.

Step 2: Mixing Dry Ingredients

  • In a mixing bowl, combine the measured frit, kaolin, silica, and metal oxides.
  • Use a spatula or scraper to thoroughly mix the dry ingredients until they are evenly distributed.

Step 3: Wet Mixing

  • Transfer the mixed dry ingredients into a ball mill or use a mortar and pestle for smaller batches.
  • Add water gradually while continuously mixing until you achieve a smooth, homogenous slurry consistency. The amount of water needed may vary, so add it slowly to avoid over-saturation.

Step 4: Grinding (Optional)

  • If using a ball mill, grind the mixture for several hours to ensure thorough dispersion of particles and a finer consistency. This step helps enhance the stability and color intensity of the underglaze.

Step 5: Sieving

  • Pass the mixture through a fine mesh sieve to remove any lumps or impurities. This step ensures a smooth and uniform texture in the underglaze.

Step 6: Adjusting Consistency (Optional)

  • Depending on your preference, you can adjust the consistency of the underglaze by adding more water for a thinner application or additional dry ingredients for a thicker application. Mix thoroughly to incorporate any adjustments.

Step 7: Testing and Adjusting Color

  • Before applying the underglaze to your ceramic pieces, conduct test firings to assess the color outcome. You can adjust the color intensity by experimenting with different ratios of metal oxides or adding additional colorants as needed.

Step 8: Storing and Application

  • Store the prepared spectrum underglaze in airtight containers to prevent drying out.
  • When ready to use, apply the underglaze to your pottery pieces using your preferred method (brushing, dipping, spraying, etc.).
  • Allow the underglaze to dry completely before proceeding with the final glaze firing.

Safety Precautions

  • Always wear appropriate safety gear, including gloves, masks, and goggles, when handling raw materials and mixing chemicals.
  • Work in a well-ventilated area to minimize exposure to dust and fumes.
  • Follow all safety guidelines provided by manufacturers for handling and storing chemicals.


With this newfound knowledge of making spectrum underglaze, you’ve unlocked the door to a world of boundless creativity and expression within the pottery scene. As you embark on your ceramic journey, armed with the ability to craft your own vibrant spectrum underglazes, remember that the process is just as fulfilling as the end result.

Embrace the opportunity to experiment with an array of colors, techniques, and applications, allowing your imagination to soar as you mold and shape your ceramic creations. Whether you’re adding intricate details to a functional mug, painting a vivid landscape onto a decorative vase, or exploring abstract patterns on a sculptural piece, each stroke of underglaze is a brushstroke of your artistic identity.

As you immerse yourself in the rich artistic community of Nashville, don’t hesitate to share your knowledge and passion with fellow potters and enthusiasts. Collaborate, learn, and grow together, fostering a culture of creativity and innovation within the local pottery scene.

Why OP Shops Are Your Secret Weapon for Sustainable Shopping

Known as thrift stores or charity shops in the US, Australia’s op shops are a treasure trove of clothing from every era. These shops – also called opportunity shops – raise money for charities.


Buying secondhand has long been seen as a sustainable choice, with shoppers snagging unique brag-worthy pieces while supporting their community. However, a closer look at the reality of op shopping reveals that not all is as it seems.

1. Support your local community

In an era of globalisation and corporate chains, many consumers are drawn to the personalized feeling that comes with supporting local business. Local businesses are also often more committed to giving back, which further reinforces the sense of community that a customer feels when buying from them.


In Australia, most suburbs and small town centres have op shops operated by Salvation Army, St Vincent de Paul Society (colloquially known as Vinnies), Lifeline and other charity organisations that support those doing it tough. They typically have a wide range of clothing, furniture and household goods for sale.


The op shop is a true treasure trove for those looking to find that perfect piece at a much lower cost than it would have been retailed. But it’s not just for penny-pinchers – the op shop has become a magnet for ‘opportunity shoppers’ who love the thrill of scouring racks and shelves in search of hidden gems. With increased awareness about the environmental impact of mass production and shorter fashion cycles, op shopping is set to become even more popular.


2. Save money

As any op-shopper knows, finding those coveted bargains can save you a packet. And for many shoppers, op shopping is more than just penny pinching – it’s also an act of sustainability. With many second hand stores donating all profits back to charity, it’s no surprise that they are seen as part of the circular economy.


Sacred Heart Mission’s op shops, for example, support people experiencing homelessness and work with communities to connect them to services. They have seen a recent boom in people visiting the stores looking for long lasting pantry items that can help their budgets stretch further, and for those wanting to make their purchasing choices reflect their values of sustainability.


While many op-shops have been operating in Australia for years, their popularity has surged with the rise of cossie-livers concerned about the environmental impacts of fashion and a desire to reduce their waste. However, as the fashion cycle continues to whirl at dizzying speeds, they are struggling to keep up with the demand.

3. Find unique items

You can find unique clothing pieces, accessories and household items at Diamond Creek op shop. If you’re crafty, you can repurpose your op shop finds like my friend Cintia did by making a leather bag out of an old leather jacket she found at her local op store. You can also get a head start on your next DIY project by picking up some raw materials at an affordable price.


Many op shops are run by charities like Salvation Army, St Vincent de Paul Society (colloquially known as Vinnies) and Lifeline who use the proceeds to help people in need. They also sell goods that have been donated by the community.


The popularity of op shops is growing, partly due to the focus on sustainable shopping and reducing waste. People are op shopping not only because it’s cheap but also because it feels great to be able to give back while finding something new, unique and affordable. It’s also a fun way to keep up with the latest trends without having to spend the big bucks.


4. Support the environment

Purchasing sustainably means choosing products and services that align with your values. This is because every product you buy has health, environmental and social impacts throughout its lifecycle. From the raw materials it uses to its manufacturing, transport and disposal, sustainable shopping aims to limit these impacts as much as possible.


Charity op shops are an essential part of the circular economy, providing secondhand goods for low prices and reducing landfill waste. They also help fund social welfare initiatives, from disaster relief to refugee support.


While it may seem like op shops are the enemy of the fashion industry, they actually have a big impact on sustainability. Australians are some of the world’s biggest fashion consumers, resulting in an oversupply of clothes that op shops struggle to sell.


But by selling unwanted clothes, charity shops and op shops reduce the demand for new clothing. This means fewer clothes are produced in the long run, decreasing both the energy and water used during manufacturing and the harmful chemicals released into the environment. Plus, it saves on transportation emissions, which are a significant contributor to greenhouse gasses.

5. Give back

In Australia alone, op shops save 59% of electricity consumption, 57% of water and 14% of greenhouse gas emissions by diverting pre-loved clothes from landfill. Despite this, they are only able to sell about 10% of the clothes donated.


According to author and op-shopper Robyn Annear, consumers are growing more aware of the environmental impact caused by purchasing new clothes and discarding them after just one wear. She believes this is driving the resurgence of second-hand shopping, as more people seek out those elusive bargains.


While this is good news for the environment, it’s also great news for local businesses. Consumers are increasingly interested in where they spend their money, and more than 82% of them take social responsibility into consideration when making a purchase. As a result, companies who actively engage with their local community are more likely to win customers’ loyalty. In addition, research has shown that giving back is beneficial for employee morale. In turn, this translates to higher customer satisfaction levels and ultimately, increased business revenue.
