Is Bullseye glass COE 90?
Glass users who ask this question usually want to know if they can successfully fuse Bullseye with another manufacturer’s glasses. Unfortunately, the answer to this question is not simple. Our short response is this:

• Matching COEs does not ensure compatibility between glasses, in spite of what you’ve read or heard from other practitioners or glass manufacturers.
• Our fusible glasses are factory tested for compatibility with each other. We do not test for compatibility with other manufacturers’ glasses. We do not test for COE or rate our glasses with COE numbers. We do not claim to produce glasses that are rated “COE 90.”
• The ONLY way you can insure that a Bullseye glass will be compatible with another manufacturer’s glass is to conduct your own tests.

We strongly recommend that you click here to read our TechNotes 3: Compatibility of Glasses, which explains this complex and important matter in greater depth.

What can I expect from Bullseye Rods?
EVALUATED CHARACTERISTICS
In the production of Bullseye rods, five characteristics are evaluated:

• Compatibility: Bullseye Compatible rod styles are factory tested to the same standards as other Bullseye Compatible materials for kilnforming.
• Color: Hue, saturation and opacity are evaluated.
• Shape: Diameter, roundness and straightness/warp are evaluated.
• Clarity: Rods must fall within an acceptable range for bubbles, stones and surface qualities.
• Overall performance: Color striking and workability are evaluated.

GRADES

• T grade rods are formulated for flameworking and are not recommended for kilnforming. They include Lustres, Opaques, and other styles.
• F grade rods can be used for both flameworking and kilnforming. They are part of the Bullseye Compatible product line.
• F and T grades may be combined reliably in the torch.

KILNFORMING WITH F GRADE RODS
The material characteristics of F grade rods relate closely to the Bullseye sheet glass palette, with some noteworthy differences, generally driven by the rod-forming process and the nature of the form itself. Comparisons to 3mm sheet glass are drawn here.

• Transparents
  It is important to consider how color saturation relates to volume and thickness of form. The diameter of a rod is greater than the thickness of standard 3mm sheet and displays more saturated color. Many styles are highly saturated and will reveal lighter coloration if used in small amounts, displaced and thinned through kilnforming methods, or ultimately coldworked to remove material. Conversely, the 001800 series has subtle coloration and much greater transparency, which is suitable for working thicker or as visual representation of negative space in thinner works. For medium color saturation, the 001500 series (currently unique to rod) has less color saturation and more transparency than its 001400 counterpart. As a general guideline, color saturation decreases as the style number increases. Striking transparent pinks and purples likely contain a linear streaked design along the length of the rod, which may also be visible if fired on end. Linear streaking is most prevalent in the following glasses: 001215, 001232, 001234, 001305, 001311, 001334 and 001342. Hue and saturation may also differ slightly when compared to sheet glass; a wider range is accepted due to changes that occur in the forming process.
• Opalescents
  Expect more variation in opalescent rods when compared to sheet glass, with several styles taking on both greater opacity and lighter coloration. This visible shift occurs in sulfur glasses during the forming process and remains stable through kilnforming. Similar comparisons in color and opacity could also be drawn between sheet glass and stringer. (See www.bullseyeglass.com/torchtips for more information about sulfur content.)
  When viewed on end, opalescent rods may exhibit a small dark spot—a core that runs the length of the rod. Whether it is a darker version of the rod color or transparent in nature, it generally remains stable through firings and can be used as a design element. This too, is a result of the forming process.

How is Bullseye rod graded?

• “F” rod is recommended for kilnwork or torchwork. All but 17 of our current styles are graded “F”.
• “T” rod is recommended for torchwork only. Only 17 of our current styles are graded “T”.

The “F” and “T” grades were created to help kilnworkers who want to incorporate rods in fused work. The grades are essentially irrelevant for torchworkers, since all Bullseye rods are recommended for torchwork.

The rod grades are easy to locate using the search tools in our online store. Our TorchTips section contains kilnforming notes for each fusible rod style.
return

Is all Bullseye glass recommended for fusing?
No. Our top-quality sheet glass comes in two grades: Fusible and Standard (non-fusible). Fusible glass is coded as “F” and Standard or non-fusible glass is coded as “P.”

• “Fusible” glasses pass factory testing for color and fusing compatibility. They carry the “Bullseye Compatible” label and are recommended for kilnwork and flamework, as well as cold applications.
• “Standard” glasses pass factory testing for color, but are not designed for fusing. They are recommended for cold applications such as stained glass, mosaic, copper foil, and leaded work.

We also offer second-quality sheet glass in two grades: Fusible-Curious and Curious. “Fusible-Curious” glass is fusible, but “Curious” glass is not. For more information on these products, see the following question/answer. To learn more about our coding/grading system, click here.
return

Is Bullseye glass compatible in all conditions?
Bullseye glasses are well known for reliable compatibility. But understanding the conditions of our factory testing is important, especially for anyone firing glass under unusual or extreme conditions. To learn about our compatibility standards, click here.
return

How do Bullseye glass colors look after firing?
Some of our glasses look the same before and after firing. Others mature or “strike” to their target colors during firing. The images of fusible glasses on this site show how colors appear before and after heatwork. If you study these images and still have questions, don't hesitate to contact our color-savvy sales associates (Monday-Friday, 7-5 PST; 503.232.8887; toll free 888.220.3002; sales@bullseyeglass.com). Note: If you plan to subject glass to repeated firing or exceptional heatwork, we recommend that you test samples of the glass to the required processes and firing cycles in order to most accurately predict color outcomes.
return

Is Bullseye glass food safe? Does it contain lead or cadmium?
Below we have listed the Bullseye glasses that contain more than 1.0% lead or more than 0.5% cadmium. If you are using any of these styles for food-bearing objects, we recommend capping them with our clear glass. In our tests we have found that clear-capping results in minimal lead and cadmium leaching, well below FDA limits. In our tests we have also found that transparent glasses leach lead/cadmium at levels below FDA limits, and much less than opalescent lead/cadmium-bearing glasses; so you may be able to use transparent lead/cadmium-bearing glasses without clear-capping. Our testing, however, does not cover all glass styles or firing conditions, and it cannot be taken as a guarantee of food safety when using these glasses. If you are selling food-bearing objects, it is your responsibility to have them tested, since lead/cadmium leaching can be affected by the specific processes to which the glass is subjected. A heavily textured surface, for example, has more total surface area and, therefore, more area from which lead/cadmium may be leached. A local chemistry lab should be able to perform the necessary test for you, according to ASTM C738-94(2006) Standard Test Method for Lead and Cadmium Extracted from Glazed Ceramic Surfaces, for a relatively low fee of around $30 to $70 dollars per sample.

The following glasses contain more than 1.0% lead: 000014, 000243, 000301, 000303, 000305, 000313, 000332, 000334, 001205, 001215, 001234, 001311, 001305, 001332, 001334, 001342, 001701, 001707, 001714, 001717, 001823, 001824, 001831, 002020, 002050, 002130, 002137, 002164, 002302, 002305, 002310, 002311, 003026, 003045, 003126, 003328, 003334, 003345, 003346, 003445, and 003446.
The following glasses contain more than 0.5% cadmium: 000024, 000025, 000120, 000124, 000125, 000126, 000203, 000220, 000224, 000225, 000227, 000310, 000320, 000321, 000329, 000337, 001119, 001120, 001120, 001122, 001125, 001126, 001320, 001321, 001322, 002121, and 002125.

What firing schedule should I use?
Firing schedules may differ from project to project. To learn general principles for designing firing schedules, read TechNotes 4: Heat & Glass. To learn about firing specific types of projects, such as plates or thick blocks, consult our TipSheets.
return

What annealing schedule should I use?
• To learn general annealing principles, read TechNotes 4: Heat & Glass.
• To learn about annealing specific types of projects, consult our TipSheets.
• If you are annealing large work, you will want to study our Annealing Chart for Thick Slabs and TechNotes 7: Monitoring Kiln Temperatures for Successful Annealing.
• Please note that we are currently revising our technical documents to reflect a recent change to our recommended annealing cycle. Specifically, as of June 2009, the recommended anneal soak temperature has been lowered from 960°F/516°C to 900°F/482°C. We now consider 900°F/482°C to be more practical, especially on larger, thicker projects. However, effective annealing has been and can be accomplished when the soak is performed at 960°F/516°C and there is no need to worry about work that has been made using the higher temperature. To learn more, read our Annealing Change FAQ.

What are Curious glasses?
The grading system for our handmade glass demands that each sheet match a target color and have a uniform appearance to receive first-quality grade. Glass that is not quite the target color or that has some other irregularity is graded “Curious” and is sold at a discount. Curious glass that is fusible is graded “Fusible-Curious” and is also sold at a discount. Fusible-Curious sheets are held to the same compatibility requirements as first-quality sheets. Our Curious and Fusible-Curious sheets are excellent for one-of-a-kind projects and are a great value for your dollar. Some of these sheets may be found in the Specials section of our online store. A much wider selection is available when you order by phone or e-mail or when you shop at our Resource Center and some regional dealerships.
return

What are Special Production glasses?
Occasionally we produce limited runs of top grade glass styles that are not included in our regular product line. We refer to these as “Special Production” sheets. Special Production sheets may be one-of-a-kind or available in multiples. They may be fusible or non-fusible. Some Special Production sheets may be found in the Specials section of our online store. Often, a wider selection is available when you order by phone or e-mail or when you shop at our Resource Center and some regional dealerships.
return

What are “striking” glass colors?
A small number of Bullseye glasses appear pale or colorless in the cold sheet, but “strike” or change dramatically to target color when fired. The images of striking glasses on this site show how colors appear before and after firing. Striking colors can vary, depending on temperature, atmosphere and amount of heatwork. For projects that are especially color-sensitive, we recommend fusing or torchworking a small sample of striking glasses before use to best predict final color results.
