[2][1] Tynell started her career in 1943 designing for Arabia, a leading Finnish housewares and ceramics manufacturer.

[2] Tynell is best known for practical designs, purposefully created for large-scale manufacturing and everyday use.

However, she herself was more interested in glass sculpture, experimenting with abstract forms, and other artistic pursuits, using both casting and blowing as well as other techniques.

[2][4] One of her best-known designs is a vase called Aurinkopullo ('Sun Bottle'), which was produced in the 1960s and 70s in at least 19 different colours and several sizes.

In 2018, to mark the 100th anniversary of Tynell's birth, a limited run of 300 pieces was produced.
