Vases

There are 8 vases in the Glass Factory differing in colour and shape. These are tied to the puzzle panel used to gain entry into the building. The puzzle has 8 different solutions and each solution raises the vase which has the same shape as the one you just drew.

The yellow vase is used in an environmental puzzle but it is unknown whether raising the other vases has any use.

It's theorised that it would be possible to enter a code into the game using these vases.
