How Kiln-Formed Glass Inspired the Phillip Rothwell Art Collection

Every artwork in the Phillip Rothwell Art collection begins with glass.

Long before these images became contemporary wall art prints and digital downloads, they existed as physical kiln-formed glass artworks. The colours, textures, fractures and flowing patterns that define the collection today were first created through heat, gravity and the often unpredictable behaviour of molten glass.

The origins of these works stretch back to a period between 2002 and 2012, when I was

actively working with kiln-formed glass from my studio in Kent. During those years I explored the creative possibilities of glass as both a craft material and an artistic medium, producing a wide range of fused and kiln-worked pieces that would eventually form the foundation of what is now the Phillip Rothwell Art collection.

Unlike traditional stained glass, where coloured pieces are cut and assembled, kiln-formed glass allows layers of glass to be fused together at high temperatures. During firing, the glass softens, flows and interacts in ways that can never be completely controlled. This balance between intention and unpredictability became one of the most fascinating aspects of the process.

Some pieces developed intricate networks of lines resembling geological fault structures. Others produced delicate cellular formations, organic textures or flowing bands of colour that appeared almost painterly. Heat, time and gravity became creative partners, influencing the final result in ways that often exceeded the original design.

What intrigued me most was that the finished glass frequently suggested landscapes, coastlines, aerial views and abstract natural forms. Looking closely at a fused glass panel could reveal details that were not obvious during its creation. Tiny fractures, colour transitions and surface textures combined to create visual stories that seemed to emerge naturally from the material itself.

In 2017 I relocated to Lincolnshire, but the glass artworks created during those earlier years remained an important part of my creative journey. Years later, while revisiting photographs of the original pieces, I began to see them in a new way. Details that had once been part of a larger artwork suddenly took on a life of their own. Patterns hidden within the glass revealed striking compositions, textures and colour relationships that inspired a completely new creative direction.

Advances in digital imaging made it possible to capture the subtle detail of the original glass with remarkable clarity. High-resolution photography allowed textures, colour gradients and structural patterns to be preserved and explored in ways that were often difficult to appreciate when viewing the physical pieces alone.

reinterprets them.

Each design begins with a photograph of a kiln-formed glass piece and evolves through a careful creative process. Certain details are emphasised, compositions are refined and visual elements are developed to create artwork that stands independently as a contemporary print. The aim is not to replicate the glass exactly but to reveal and celebrate the hidden beauty contained within it.

This approach allows the collection to occupy a unique space between traditional craft and digital art.

The original glass provides authenticity, texture and visual depth. The digital process offers freedom to explore composition, scale and presentation. Together they create artworks that retain the character of the kiln-formed originals while becoming something entirely new.

Many titles within the collection reflect this relationship between glass and landscape. Works such as Amber Strata, Blue Kintsugi Field, Cranberry Constellation and Celadon Drift draw inspiration from geological formations, natural patterns and imagined environments suggested by the glass itself. These names are not descriptions of specific places but responses to the emotions and visual associations that emerged during the creative process.

The collection also reflects a long-standing appreciation for the beauty of imperfection. In kiln-formed glass, unexpected lines, fractures and variations often become the most compelling features. What might initially appear to be flaws frequently contribute character, movement and individuality. These qualities remain central to the artwork presented today.

Ultimately, the Phillip Rothwell Art collection is a celebration of transformation.

Glass is transformed by heat within the kiln. The resulting artworks are transformed again through photography and digital interpretation. Each stage builds upon the previous one, creating a creative journey that spans more than two decades.

The finished prints may hang on a wall as contemporary abstract art, but their origins remain rooted in the kiln-formed glass artworks created in a Kent studio during the early years of the millennium. Today, from my Lincolnshire base, those original pieces continue to inspire new interpretations, proving that creative ideas can evolve and find fresh expression many years after they were first brought to life.

Every piece in the collection carries a small part of that journey.
