About Acid Yellow Crayon, 301

Acid Yellow Crayon is a dense, vibrant opaque cadmium yellow borosilicate glass—pushed toward a bright, lemony tone while maintaining maximum density.

It stays true to color when worked thin, holding opacity down to approximately 2mm, making it reliable for detail work, murrine, and larger lampworking applications.

A strong backing color for Glass Alchemy transparents, it provides clean coverage and pairs well across the opaque palette.

Part of the Glass Alchemy Crayon collection. If you prefer a more traditional yellow, try Yellow Crayon.

Working Tip: Pre-heat in outer flame. Avoid rapid heating

Artist Description by Mike Shelbo:

"This very bright opaque yellow will stay true when drawn down to smaller cane sizes and will not transmit light unless the application of color is thinner than 2mm.

This color works great in the neutral flame region and can handle all flame atmospheres for short amounts of time. Do not use a highly reducing flame or a very sharp hot flame without quick movement of the color; this will avoid any possibility of minor boil spots.

The vibrancy of Acid Yellow Crayon is a wonderful backing to many Glass Alchemy transparent colors, also a very complimentary color to the other opaques, and desirable for murine applications as well. Encasement in clear is not necessary but can be used to increase yield on size of solid or blown work and allow for more intense working conditions." - Mike Shelbo
