There is a two-toned ball in the Sarpaneva Kokoelma Collection book described this way (it is clear on the bottom and blue on the top, with a small hole at the top):
Art Object Iso tantrapallo (large tantric ball)
1957
Glass, turned mold blown
D 135
Signed Timo Sarpanva
32926
The bowl and plate are a little bit difficult to distinguish, but the blow could be:
Bow, li-301; 2301
1956
glassi-colors
turned mold blown, flared base cut
D 175, 275
signed Timo Sarpaneva
Iittala-57 (green) i-301 (blue)
The plate could be:
Plate Ikava (Yearning)
1956
glass, i-colors
turned-mold blown
D 350
32635
There are other plates and bowls but if these are the correct ones, they would all be from the same vintage and might certainly have been purchased together.
Great pieces. Good luck with them.
