Originally popular in Victorian windows, English Muffle glass is being reintroduced in both restoration and contemporary stained glass work. English Muffle glass is known for its traditional muted colours, its highly refractive texture and crystalline quality. The texture appears as a non-directional ripple, allowing for minimal waste. Glass Disclaimer: Our online glass photo's are meant to give the stained glass artist a general idea of the colour and texture that you would receive when purchasing glass. Please note that every sheet of glass is unique and therefore the images you see should only be used as a guideline. Also, computer settings such as the gamma setting on your monitor and the amount of display colours on your video card may alter the colours of the images on your screen. When calculating quantity needed, please keep in mind the sizes (where listed) are approximate, due to variations in production.
