CiM Tester Feedback

  • Testers agreed that Grumpy Bear & periwinkle are similar but disagreed on which they prefer.
"I can’t honestly say that there is much of a difference between Grumpy Bear and periwinkle. If anything, the Grumpy Bear is a bit 'stiffer' than the Italian but not enough to make much of a difference." – Chris Haussler
"Grumpy Bear is a much nicer colour in my opinion, more vibrant with more 'ooomph'." – Claire Morris
"I found Grumpy Bear had a bit deeper color to it than the periwinkle." – Donna Dorman
"Grumpy Bear's hue is spot on to periwinkle and will be a replacement for me since I know it won’t shatter just looking at it. [Again, another color that is just too shocky now from Italian glasses]." – Elasia
"Grumpy Bear is slightly darker than periwinkle." – Elizabeth Long
"I have been trying to find a light blue with which I can make encased flowers. I’ve mainly tried working with Periwinkle, and the results vary depending on which lot I’m using. When I tried using Grumpy Bear, the petals couldn’t keep a hard edge and the results were that the flowers looked very ethereal, which was not what I was going for." – Gail Witt
"Grumpy Bear is much darker than the periwinkle that I have. I was able to get wonderful colors out of Raku on this color." – Jan Whitesel-Keeton
"Italian periwinkle is stiffer and reacts more with dark ivory, it lets ivory spread more. Grumpy Bear is streakier and a little darker. When reduced strongly, both colours reduced to purple-gray." – Maija-Leena Autio
"I use Grumpy Bear & periwinkle interchangeably." – Renee Wiggins
"Made a spacer bead with Grumpy Bear over periwinkle and they both look pretty much the same." – Leslie Anne Bitgood

"Grumpy Bear is an opaque periwinkle blue just like the CareBear character. As a periwinkle it does create some reactions based on what you combine with it, so I tested it in this faux 'vessel' shaped bead with some handmade frit and a wrapping of fine silver wire. This is where you see a slight bit of the reaction where the wire touches the Grumpy Bear. I encased the bead's Grumpy Bear base with Splash and created the ends of the barrel shaped bead and a final quick wrap of more silver." Read more at Darlene's blog.

"The other dot bead is Effetre Light Ivory on Grumpy Bear. A little bleeding/fuzzing at the edges, but not much. Very pretty blue." Read more at DragonJools blog.

"This is a Grumpy Bear base with silver foil and superheated Hades stringer, encased in Effetre clear. When combined with silver foil, Grumpy Bear goes a stone brown."
Claire Morris
"As I have said before, I think the colour of Grumpy Bear's colour has a little more oomph than Effetre Periwinkle. I'm not sure that it is different enough though to warrant buying that as opposed to Effetre. I remain undecided! I found that when I made a set of beads with Grumpy Bear as a base with superheated Raku and Hades murrini, it got 'pushed' by the murrini and created little veins of denser colour around it."

"Grumpy Bear makes an especially gorgeous base for frit blends. It gets that fabulous reaction halo from gold-based glass colors."
Patricia Frantz
"I really like Grumpy Bear, it’s very dense and saturated, but in my florals, it seems to be too dense. Using the same Effetre Ink Blue for top color of flowers, somehow they just aren’t as striking and colorful as when used with Effetre Periwinkle."

"My Grumpy Bear test beads are by far my favorite of the silvered shard test beads, with a secondary organic effect of brown striations appearing during the application process." Read more at the Kitzbitz Art Glass blog.

"This rose cane is also Grumpy Bear with 2 layers of Cranberry on top. Notice how much more saturated the color is when left raised." Read more about Grumpy Bear and Cranberry Pink combinations at Genea's blog.
