Hello
I have once before some time read in a Museum, such as the ancient Egyptians in their flowers preserved (but probably not Amorphophallus). I can vorsstellen me but that it is likely even in Amorphophallus. (more still times below)
It is somewhat expensive, but should be doable.
I have never tried it.
So now to the technology:
What it takes:
-fine, dry sand
-a crate box, which is not airtight (should but no sand to below allow)
-a warm, dry area (in summer may be outdoors)
What to do:
Fill some sand in the box, so that you have a nice layer (probably ca at least. 5 cm thick).
Then, you put the flower on this layer. Then you begin to slowly layers carefully cover the remaining sand of the flower and also the accessible cavities must be filled so the flower must also "filled".
You do this until the flower is fully covered.
Now you dry it until the flower is completely dry. It may be damp nothing, otherwise form mold.
The colors are very well preserved during this technique and the shape is also nearly as as before, because the flower is embedded on drying Yes not could warp in the sand.
Now again to the possible problems:
The Egyptians had preserved so I understand just fine, so thin-leafed flowers.
Amorphophallus-flowers are very meaty and the peduncle, as also the spadix are often quite thick and rather porous, almost hollow. Aufgrudn the thickness will dry hard and very slowly complete these flower parts and could verschimmeln therefore from the inside because there still too much moisture. You should then increase the temperature to and keep the humidity as low as possible that even these flower parts dry quickly. However, that must go to the colour. (because to this process, the Egyptians used a special temperature.) It is different or exceeded, then the Präperat is subsequently not so perfect)
On basic food, that they are so porous and almost hollow, it is also possible that this flower parts under the pressure of the sand drying deform as they coincide.
It is perhaps still worth an attempt.
With kind regards
Stefan
