"In my career I have mostly worked with lead-based enamels as I had the prejudice that lead-free enamels were less beautiful. After trying the enamels by W.G. Ball, I had to change my mind. These enamels are excellent, especially transparent colours, which are more resistant to prolonged firing. The enamels of W.G. Balls have good compatibility with other brands, including lead-based brands."
