Black Galaxy Glass Tumbler
Black Galaxy Glass Tumbler
Handblown glass tumbler made by me! Use these to drink wine, beer, or whatever the hell else you’d like. These tumblers feature an original coloring process meant to create a rich contrast. The process for making these is quite involved but necessary to achieve my desired balance of color and form. (See below for the process)
Tumblers range from 3.5”-3.75” tall. Each tumbler is unique so you may not get the exact ones pictured. Hand wash recommended.
The Process:
Gather glass, color in black powder, then gather solid glass color strings onto the glass
Introduce a bubble into the glass; the glass expands causing the opaque colors to dilute
Shape glass using wood, metal, and paper to the desired shape
Place tumbler into kiln to anneal, a process in which the glass is cooled to room temp
At this point, the tumbler looks like a cone; the excess material is hot popped using a small torch, thus the mouth of the glass is revealed
The mouth of the cup is ground down using diamond lapidary disks and placed in the kiln; the kiln is brought up to 1150 degrees Fahrenheit
I pull the tumblers out and flame polish the mouth of the tumbler thereby rounding the tumbler mouth
The tumbler is placed back into the kiln to cool down and TA-DAAAA! A tumbler is born!
These tumblers feature metallic spots. This was an unforeseen occurrence. Certain colors react with one another resulting in a reduction reaction. The metals that create the color come to the surface, losing their previous appearance.
