Glass Color for Sculpture Design

The glass colors for sculpture design comes in different forms. We use several types of glass colors to create our hand blown glass sculptures. The opaque textures are created with different size Frit (color chunks) shown below.


Glass Color

To create our transparent parts of our glass sculptures, we use  Glass Color Rods, which can can come in both opaque and transparent colors.  Peek into our cabinet filled with lots of glass color choices.

Color Rods

When we create a new color combination, we experiment to see which colors work  well together in design. Glass colors can heat and melt at different temperatures, which we refer to soft and hard colors.

Depending on what is within the color, such as Gold Topaz, which actually does have Gold within the color. Colors can also be rather costly. To save on costs, we use color samples from our main color supplier East Bay Color.

We blow glass color samples to send to our clients to view. As shown for our Wall Project Installation.

Knowing the basics about our glass color, can help our trade design clients understand, what constraints we may have in designing custom glass colors.

Making of a Glass Tree Vase

After 25 years of creating the Tree Series, I wanted to share the making of a glass tree vase.

Each glass vessel created within our glassblowing studio, is made with a  team of three,  including Bernard. As shown below, the glassblowing team are making the Bellied Root Vessel. Hot glass bits  attached to the glass vessel create three-dimensional roots at the base.









The blown glass vase is placed in the  annealing ovens. The annealing ovens slowly cool down the work to room temperature. Without the annealing process, a piece can break apart.

The Birch Vase on the left, is carved by hand to show the beautiful notches found on Birch Trees.

Bernard sandblasts each vase which reveals the inner color and the design of the tree branches.

From start to finish, a vase from our Tree & Root Series can take two weeks to create.

Painting with Molten Glass interview with Wes Hunting


Katie Katz  interview with Wes Hunting  Glass Artist

At the Baltimore Craft Show, I had a chance to sit down with glass artist Wes Hunting of Wes Hunting Studio Glassworks. This was really exciting for me, since I have not seen Wes for over 5 years!  Throughout his 37 years as a glass artist, Wes always impressed me with his approach to glass making.  As Wes describes it, ” it’s all about being able to make  what I want, when I want, and keep it moving until I can no longer do so.”


Wes Hunting, discussed his latest glass series, The Color Field Vessels.  The Vessels originally began in 1984 and are continued today. The glass technique used to create the wildly colorful series is “Millefiori.” I am particularly drawn to the organic forms of each glass vessel.


Another body of work, that takes Wes quite of bit of time to create each sculpture is the Crystal Portal Series. The layers of clear glass with the colorful millefiori designs blown within each sculpture. Rather amazing to learn about Wes’s process of creating each one, which he describes as “painting with molten glass.”

Tree Vase and Vessel in Glass

25 Years

Enjoying 25 years of creating the Tree Vase and Vessel in glass by Bernard Katz. The Tree Vase pictured here, was inspired by a view from a third floor window.

While the Tree & Root Series is a timeless collection, both Bernard and I are ready to move on. We will no longer be making vases and vessels from the Tree & Root Series.

We would love to give you all an opportunity to have one last time to order from what we already have in stock.
