Glass Size Variance
At times, our glass will be listed as a specific size. We try our best to assure all our glass is as close to the listed size, but can have some disparity, which means the glass could be cut under or cut over the listed size. Standard size variance can range from ¼” under to ¾” over, which can create issues if you are directly installing the glass, or have a specific need that is size dependent.
In order to offset this issue, please let us know in the order notes if you are in need of exact sizes and are unable to do trimming or size adjustments on the glass yourself. We are more than happy to cut the piece to the exact size you need and will make sure your order is to your satisfaction.
Dalle De Verre
What is Dalle De Verre Glass?
Dalle De Verre, french for slab glass is made from the same pots as our stained glass. It is poured into a 12” x 8” mold to a thickness of approximately 1”. Projects containing Dalle De Verre will involve breaking (usually with a hammer) or cutting the slabs into pieces and placing them in a mold box then placing epoxy between the pieces in a very careful manner. Feel free to contact us about using our dalles in your projects.
Can I use Dalle De Verre instead of billits?
We do not recommend using our dalles as billet for casting as they can be made using cullet and greatly affect the outcome of your project.
Do you have Samples?
Yes! We offer a sample box of our Dalle De Verre glass which contains 2” x 3” pieces of the actual dalle slabs. These pieces are rough cut and may contain sharp edges.
What are Rondels?
A mouth blown glass art piece that has been spun into a circular shape, often irregular. Sometimes incorporated into leaded glass artworks. Rondels are fun, colorful and exciting hot glass products that you can use to add interest to your stained glass creations. They are round and can be in sizes from 2” to 20” and are available in a huge selection of colors and styles to suit your needs. You can see many examples of finished installations in our Gallery.
What Types, Styles and Sizes do you have?
Rondels are available in two types, Spun and Blown. We have sizes ranging from 2” to 20”. We have tried to showcase the wide variety of styles from the Optic, Wacky Wrap, Hot Wrap, Murrini, Frit Swirl, Feathered, and solid colors for sale in the Rondel section of this website. If you need something special, Contact Us.
What is the difference between a Spun and Blown Rondel?
At first blush, they may appear very similar. A blown glass art rondel is as it sounds, glass is gathered and blown into a bubble. That bubble is then piereced and opened into the flat shape then broken off leaving a thicker portion at the center called a punty. Blown rondels are made from both clear glass and clear glass with a color overlay called flashing and are available in sizes from 3” to 20”. A Spun rondel is always made from colored glass, unless it is supposed to be clear, and is shaped from a gather of glass then formed with a “footing” tool to the correct size. Spun rondels have a punty, are thicker than blown rondels, more economical, only available in sizes 2” – 4” and have a standard color pallet that you can find under our Rondel section of this site. Other colors can be made with a minimum order of 20 rondels per color, please Contact Us for a price quote and availability. Both Spun and Blown rondels can be incorporated into stained glass projects with lead cane or copper foil.
Do you have samples?
Yes! We offer a Rondel sample set that contains one 3” Blown rondel, 3” Spun rondel and samples of our standard rondel color pallet available in the form of 2” x 3” sheet glass samples and is available in our Samples section of this site.
