Directions for bringing out the coppery color: You must use an all propane or all Mapp Gas torch for this glass. Before we work on a bead, let's try something first. Turn your torch all the way up. Take a cold coppery black rod and begin to flash it into the flame about 1-2 inches from the torch head, and only for a second at a time, pulling it back out. Do this several times. It should make a loud whooshing sound each time you enter the flame with the glass rod. Keep doing this and keep an eye on the color. It will begin to turn coppery at the tip. That whooshing sound is the key. If it does not make that whooshing sound, the air/fuel mixture is not right for it to turn coppery. Now, with a bead, after you work it up, you need to cool it down some. It cannot be glowing. Begin to flash it the same way you did with the rod, with the flame way up and only a second at a time, very close to the torch head. Listen for the loud whooshing sound. That should do it. Devardi glass is a handmade, hand pulled glass that uses very ancient glass formulas. It is very saturated with color and the color remains very true even with high heat. The color of the rods are commonly the colors you will receive in your bead. Devardi is a stiffer glass than other COE 104 glasses, which can be very beneficial for decorations, encasing or sculptures. With different heat settings, most Devardi glass colors provide different effects. The opaques tend to mottle with high heat, resembling a marbled look, or remain the color of the rod with cooler flames. Different oxygen/propane mixes also can give different appearances. Devardi is generally a lower heat COE 104 glass. Once you become accustom to it, you will find it to be a great glass. Devardi glass rods are hand pulled, and therefore are not perfectly straight or uniform. And the rods will vary in width and length. But this does not affect the quality.
