I have sometimes had small parcels of paprika sent to me by post, but the experiment has not been very satisfactory; when fresh, it is an agreeable condiment, but if kept in
an open vessel it becomes dry and tasteless, whilst in a closed one it soon turns mouldy.
Raw honey is full of it; diluted four to one and left in
an open vessel, honey will ferment all by itself.
The alternative is angioplasty, which involves threading a catheter through the artery and inflating a balloon at the tip of the catheter to
open the vessel.
Most of the pieces are
open vessels and then a few are closed forms.
Need to know: There are two kinds of terrariums,
open vessels (for succulents and cacti) and closed containers for humidity - loving plants.
