Thank you, everyone, for your thoughts on these two colors. I made test beads last night and here is what I found. The yellowish glass was a tad smutty and is best when worked cool. Each stayed true to color as you can see in the picture. So I'm guessing they are Alabaster and the one on the right is Ivory (even though it looks yellow) and the one of the left is Yellow (even though it looks ivory..haha). I checked Frantz, ABR, Glass Creative, Glass Sorbet websites. Sigh this can be so confusing. thanks again
