I have experienced limited success using "silica gel" that comes packed
with instruments to prevent moisture damage. When dry the granules are
deep blue; when moist they turn white. The color preservation is the
hardest. Another process is freeze drying by dropping the temperature
under high vaccuum conditions. This may affect the looks of the
finished product as well. I have not tried this method. Cheers...:)
