|Glass Item Frame|
The Glass Item Frame is an item and entity added by Quark. It functions the same as an Item Frame. When it is empty, it look very similar to a glass plane. However, when an item is in it, the Glass Item Frame will become invisible, only showing the item. Like a normal item frame, it can be placed in the same block as another transparent, non-full block, as well as be crafted into a glowing variant.
