Melt 45
Suppliers of Gaffer casting glass and Reichenbach 15% casting glass.
Gaffer casting glass originated in New Zealand and is a specific type of 45% lead crystal glass that is specifically formulated for glass casting. This high-quality glass is favoured by artists because it flows at low temperatures, allowing for the creation of intricate designs in cast glass work, and is available in various colors, including dichroic varieties that change colour depending on the light. Gaffer is a reliable glass which does not have to be taken up to a high temperature for it to flow, making it advantageous for molds. The high lead content in Gaffer crystal glass gives it a brilliant, refractive quality, making it visually appealing as it catches the light in a unique way.
Reichenbach casting glass is a specific type of coloured glass manufactured by the German company Farbglashütte Reichenbach GmbH that is designed for the glass casting process. Reichenbach 15% casting glass is known for its uniform melting behaviour, consistent colour palette and high quality for creating glass products. Due to its lower lead content, Reichenbach is a more cost-effective casting glass, making it perfect for beginners. The relative lightness of this product makes creating large scale works more achievable, allowing higher volume for less weight. Reichenbach is ideal for open molds and flows well, though at a higher annealing point than glasses with a greater lead content. The clarity and high refractive index of this glass result in a bright sparkle in the finished product.
