archi,
I wondered if you used the same color and was getting a totally different look or shade. I have all the colors Caswell offers and run them at 140 degrees. I have heard of several people using the dyes at room temp. and Caswell tell them that they can't offer support for dye problems if they don't use the products according to manufacturers recommendations. Understandable I think.

Honestly I didn't check the last bag for size when I dumped it in the blaster. I buy mine from a large fab company that makes ship portals and hatches. A couple of things to watch with glass bead. If you blast with too much pressure, the surface texture will be rough enough that the part will have a alum. gray tint or shade through the dye color. The fix I use for this if it happens is to strip and etch. Then re anodize and it will give a nice even color. The other common problem is people don't go over the part enough to make sure the surface finish is truly even. After blasting the part will visually look good but after anodize you will be able to see where the focus of the blast went and the rest was not hit as hard. Kind of like scribbling with the blaster gun. I usually use 50 to 70 psi and always at a 45 degree angle. I've used glass bead primarily for years and prefer it to most other media I've tried.
