About Yellow Crayon, 304

Yellow Crayon is a dense, bright opaque cadmium yellow borosilicate glass—a true school bus yellow with a natural, earthy tone.

It holds its density and color across lampworking applications, including stringers, canework, murrine, and blown glass.

The color remains solid and opaque until worked thin. 

Part of the original Glass Alchemy Crayon line, developed to deliver stable, high-density opaque cadmium colors.

If you want a more lemon-forward yellow, try Acid Yellow Crayon.

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

Artist Description by Mike Shelbo:

"This color is a true yellow opaque. It's very natural and has an earthy tone to it.

Not too dark, not too bright, Yellow Crayon is just right. Works like other crayon colors and prefers to be in the mid to outer region of the flame but can come close to the torch tip in quick passes and light repeated spot heats.

The color density holds well in stringers, canework, and murrine. Blowing with Yellow Crayon works well with encasement or color on the surface of your piece and will stay dense until the color layer is blown thinner than 1mm. Compliments and contrasts with almost the entire Glass Alchemy palette, try Yellow Crayon, 304 and Eclipse, 9977 for bumblebees or with Shamrock, 4494 for a classic combo." - Mike Shelbo
