What are the challenges of achieving symmetry in large-scale cast iron abstract sculptures?

Achieving symmetry in large-scale cast iron abstract sculptures presents several unique challenges. First, the inherent properties of cast iron, such as its weight and brittleness, complicate the casting process, often leading to distortions or uneven cooling. Second, the sheer size of these sculptures requires precise mold-making and alignment, where even minor errors can disrupt symmetry. Third, the abstract nature of the designs often lacks clear reference points, making it harder to measure and maintain balance. Additionally, environmental factors like temperature fluctuations during casting can further impact the final form. Despite these obstacles, artists employ advanced techniques like modular casting and digital modeling to overcome these challenges and create visually harmonious works.
