Kathleen Mulcahy’s glass panels imitate the look of liquid elements in nature. But there is nothing of nature’s seemingly random behavior in these compositions. Instead, Mulcahy simplifies the irregularity of organic shapes to create controlled arrangements. Her glass elements may be prompted by something observed in nature, but they have been refined to a purified geometric form carefully set in a controlled composition. Works in this series involve hot-worked and flame-worked glass shapes attached to slumped and acid etched plate glass backed by a fabricated steel sheet.The result calls to mind levees or floodgates meant to manage or prevent the flow of water.
