TorchTips

What to expect from selected Bullseye torchworking rods.

Bullseye rods are drawn from compatible Bullseye glass and are available in 94 stock styles. While we find that torchworkers are cheerful and tireless testers of new styles, we've provided a reference index to shorten the learning curve anyway. Click on one of the styles to the left and see what to expect from your Bullseye rods, before and after time in the torch.

000146-0576 Steel Blue

Contains:

May react with:

Cold characteristics
Opaque. Can have a dry surface.

Working notes

Torch: Keep the glass blue by working it in a neutral flame throughout the process and keep it uniformly heated. Develop a matte metallic surface on this glass by forming the glass in a neutral flame; next change the flame to a reducing atmosphere by turning down the oxygen. At this point the surface should begin developing a metallic quality. Then turn off the oxygen completely, and build up a layer of carbon on the glass. Put the piece away in the annealing kiln with this carbon layer on it. Once removed from the kiln, the carbon is easily removed to expose a matte metallic surface. If you return the carbonized piece to a neutral flame, the metallic surface will disappear.
Kiln: Working properties and kilnformed characteristics are consistent with sheet glass. See GlassTips.

Working notes

Torch: 000203-0576 matures to rich, dark brown in the flame.
Kiln: Lighter, yellow-side color in comparison to sheet glass form.

Other
The brown color of this style results from reactions between several of the elements that are listed as reactive with one another elsewhere on this chart. As such, it may react with many of the other glasses that contain these elements. However it is likely that the reaction will be subtle or unnoticeable due to similarities in the color of the reaction and the color of the glass. Lighter, yellow-side color in comparison to sheet glass form.

000243-0576 Translucent White

Contains:

May react with:

Cold characteristics
(Deceptively) clear or clear with a white struck streak running lengthwise down the middle of the rod.

Working notes

Torch: 000243-0576 can strike to a transparent white with stone like qualities similar to quartz. Generally speaking, the heat required to form a bead leaves the glass unstruck and clear. This glass strikes as it cools, rather than when it is heated.

Here is a series of steps that can make the striking process more efficient:

Make a bead as usual in a neutral flame. Once the bead is formed, cool it (still in the flame, but farther away from the nozzle & flash it in an out of the flame). As the glass cools to a point where it is no longer moving or slumping on the mandrel, turn off the oxygen and hold the bead in the propane (fuel) flame while still rotating the mandrel.

Do this until carbon collects on the glass (not just the mandrel). The purpose is not to actually carbonize or reduce the glass but simply to keep it at a cool, consistent temperature throughout the piece. Turn the oxygen back on and ease the bead into the neutral flame from the tip of the flame (farthest from the nozzle). Reheat the glass and bring it to a slightly molten state while keeping it cool enough to retain its shape. The carbon will burn away. At this point, briefly remove the bead from the flame. Looking closely at the bead, it should start to take on a hazy appearance with a yellow tint which is the glass beginning to strike. The bead may need a little more heat, just to equalize the temperature of the glass and to keep it warm as it gets put into a kiln for annealing.

This process holds the glass in the appropriate striking zone, and is slightly unusual for many torchworking styles. This approach may not be necessary if the style of torchwork being done involves holding the glass at cooler temperatures over a longer period of time (like some sculptural work).

Other
In making components for kilnforming, it is not necessary to strike the glass in the flame because it will strike in the subsequent kilnforming processes. On a similar note, 000243-0576 that has been struck to a translucent white in a kiln may change back to clear if worked in the flame.

It is possible to strike portions of the 000243-0576 to translucent white and leave some portions clear within the same piece. Continued work in the flame on a piece that is already opalized can "chase" the translucent white color from the molten area and concentrate it in the cooler area within a single piece.
Kiln: Opacity may vary upon firing , as the core may not strike completely. Expect variation.

000301-0576 Pink

Contains:

May react with:

Cold characteristics
Palest pink with a slight blue cast.

Working notes

Torch: Strike this glass to pink by working it in the flame, then cooling it just outside of the flame and then gradually reheating it. Once struck it should be medium to dark pink while it is still hot. If the glass looks white, continue to cool and gradually reheat the glass until it strikes. The pink is easier to strike if it has been worked in a cooler flame to begin with; try to work with it farther out in the flame, away from the nozzle. When molten, this glass has a low viscosity and can be quite soft, which may result in a blurred edge where it meets other glasses. We advise labeling all striking glasses.
Kiln: Not recommended for kilnforming.

return to top  


000303-0576 Dusty Lilac

Contains:

May react with:

Cold characteristics
Opaque, muted lilac. Can have a semi matte surface.

Working notes

Torch: 000303-0576 becomes shiny once it is worked in the flame, and remains so in the finished work. When molten, this glass has a low viscosity and can be quite soft, which may result in a blurred edge where it meets other glasses.
Kiln: Slight variation in color with different production runs.

000305-0576 Salmon Pink

Contains:

May react with:

Cold characteristics
Palest peach pink. Slightly translucent.

Working notes

Torch: Similar to 000301-0576 in nature and color, with slightly orange hues. Strike this glass to salmon pink by working it in the flame, then cooling it just outside of the flame and then gradually reheating it. Once struck it should be medium to dark orange-pink while it is still hot. If the glass looks white, continue to cool and gradually reheat the glass until it strikes. Striking this color is easier if it has been worked in a cooler flame to begin with; try to work with it farther out in the flame, away from the nozzle. When molten, this glass has a low viscosity and can be quite soft, possibly resulting in a blurred edge where it meets other glasses. We advise labeling all striking glasses.
Kiln: Not recommended for kilnforming.

000309-0576 Cinnabar

Contains:

May react with:

Cold characteristics
Opaque.

Working notes

Torch: Depending on the heatwork of the glass, as indicated by color when it is put into an annealing kiln, a range of colors may be achieved. If this glass is put into an annealing kiln with a deep brown hue, a target Cinnabar color will result in the finished piece. If it is very light beige, as opposed to deep brown, and the desired result is Cinnabar, gradually cool and reheat the glass without bringing it to a soft state. Look for it to turn deep brown and then put it into an annealing kiln.
Kiln: Lighter color and greater opacity than in sheet glass form. Rod color is close to 000329-30, Burnt Orange, after a full fuse firing.

Contains:

May react with:

Cold characteristics
Translucent, milky white.

Working notes

Torch: 000313-0576 opacifies when used in the flame. Is whitest when used as a core bead. 000313-0576 is more prone to reduction than other Bullseye styles. Keep it white by working with it in a slightly oxidizing atmosphere. Sometimes small bubbles are evident while the glass is molten, but these typically are not visible in the cold rod or the finished work.
Kiln: Not recommended for kilnforming.

000321-0576 Pumpkin Orange

Contains:

May react with:

Cold characteristics
In cold rod form, the color of 0321-0576 can vary even within the same production run.

Working notes

Torch: This style may start off as light orange, consistently developing a bright, squashy color upon use in the flame. Depending on the color of the bead when it is put away, a range of colors may be achieved. If this glass is put into an annealing kiln with a red hue, then a true pumpkin orange color will result in the finished piece. If it is very light orange as opposed to red and the desired result is a true pumpkin orange color, gradually cool and reheat the glass without bringing it to a soft state, look for it to turn red and then put it into the annealing kiln.
Kiln: Lighter color and greater opacity than in sheet glass form. Slight variation in color with different production runs.

001701-0576 Amber Lustre

Contains:

May react with:

Cold characteristics
Clear.

Working notes

Torch: A reducing glass that can develop a metallic sheen with an amber cast. Begin by working 001701-0576 in a neutral flame. When ready to develop a metallic sheen, the glass should be relatively cool (no visible heat) and stable on the mandrel. Create a reduction atmosphere by turning the propane (fuel) up and watch for the surface of the glass to become metallic. Once this has happened, the piece should be put into an annealing kiln. This is a finishing step. If the metallic surface is reintroduced to a neutral flame, it will dissipate. It can be brought out again by returning it to a reduction atmosphere. When molten, this glass has a low viscosity, and can be quite soft, which may result in a blurred edge where it meets other glasses. In addition, the process of reducing the glass can cause a metallic sheen over areas of glass immediately adjacent to this style.
Kiln: Not recommended for kilnforming.

Other
001701-0576 is a relatively heavy glass, and there are 14 rods per pound (compared with 18-20 rods per pound for most other styles). Labeling is encouraged, because 001701-0576 stays deceptively clear until reduced.

Contains:

May react with:

Cold characteristics
Pale transparent green.

Working notes

Torch: A reducing glass that can develop a metallic sheen. In some cases, this metallic sheen is transparent enough to see through it to the green glass. Start by working 001707-0576 in a neutral flame. When you are ready to develop a metallic sheen, the glass should be relatively cool (no visible heat) and stable on the mandrel. Create a reduction atmosphere by turning the propane (fuel) up and while passing the bead through the flame, watch for the surface of the glass to become metallic. Once this has happened, the piece should be put into an annealing kiln. This is a finishing step. If the metallic surface is reintroduced to a neutral flame, it will dissipate. It can be brought out again by returning it to a reduction atmosphere. When molten, this glass has a low viscosity, and can be quite soft, which may result in a blurred edge where it meets other glasses.

These various effects can be achieved by working with 001717-0576 with specific flame chemistry and heat history. Results will depend greatly upon the type of heat and forming methods required.

As 001717-0576 is heated into a gather and wound onto a mandrel, it will opalize on the rod between the gather and the cold glass. If formed hot enough, the bead will remain transparent. When you are ready to develop a metallic sheen, the glass should be relatively cool (no visible heat) and stable on the mandrel. Create a reduction atmosphere by turning the propane (fuel) up and while passing the bead through the flame, watch for the surface of the glass to become metallic. The lustre surface develops readily on cooler glass and can vary greatly depending on the length of time spent in the reduction atmosphere. Once this has happened, the piece should be put into an annealing kiln. This is a finishing step. If the metallic surface is reintroduced to a neutral flame, it will dissipate. It can be brought out again by returning it to a reduction atmosphere.

Often a design will necessitate holding the glass at a warm, stable state (cooler than molten, fluid glass). Under these conditions, 001717-0576 is likely to opalize. Once opalized, 001717-0576 may still be reduced as described above to bring out a metallic sheen, though it takes a little longer to develop. The finished appearance is different because it is backed by the opalized glass. Consider using 001717-0576 for its unique opalized color and work with it in a neutral to oxidizing atmosphere without reduction treatment.

When molten, this glass has a low viscosity, and can be quite soft, which may result in a blurred edge where it meets other glasses. In addition, the process of reducing the glass can cause a metallic sheen over areas of glass immediately adjacent to this style.
Kiln: Not recommended for kilnforming.

Other
001717-0576 is a relatively heavy glass, and there are 14 rods per pound (compared with 18-20 rods per pound for most other styles). Labeling is encouraged.

Lustre rods are not part of the Bullseye Compatible line for kilnforming and are formulated solely for flameworking with Bullseye rods. We advise labeling all lustre glasses.
