User-friendly Tumbler - Blue Riverstone By Jim Loewer Limited Time 40% Off [iCU419on]

I am pulling hot glass cane and then melting that cane into tubing to create very fine swirling lines across the top of the glass. This technique really shows the motion of the hot glass and gives a very handmade one-of-a-kind look for an affordable item. Enough color to pop, but enough clear to see the color of wine, bourbon, etc.

Blown with thick, tough, borosilicate glass, these are stronger than soft glass tumblers and are dishwasher safe! 

Dimensions: approximately 4.5" tall x 3" in diameter.

Because this item is handmade, it will vary slightly from the image shown.

Handmade by Jim Loewer of Philadelphia, Pennsylvania.


I use a propane/oxygen mix torch to melt and shape glass. The color is colored borosilicate glass rods or powder melted directly into clear glass tubing. Forms are blown and sculpted in the flame and then annealed in a kiln.

I’ve tried other career paths. I studied painting, taught art in a juvenile jail, worked on a fishing boat, and got a J.D., but I kept returning to glass. I love turning solid glass into a liquid and back again and experimenting with new ways of adding color, shaping glass, and pushing the boundaries of size for lamp-working. As a maker, I aim to make colorful, playful work that you will want to hang in your windows, decorate your house with, drink your whiskey from, and give to your mom.
