well for preserving foliage and some flowers. The main ingredient in
glycerol, (glycerin and methyl alcohol) but methyl alcohol is
toxic. Prestone makes
an antifreeze called "LowTox" that's a mixture of glycerin and
isopropyl alcohol (propylene glycol) and works the same as regular
antifreeze on plant material.
To keep greenery from turning brown,
you must add
a floral absorption dye. Certain flowers
such as Solidago (goldenrod) do well with green, red or other colors
around with different concentrations of glycerin to alcohol, trying to
determine the least amount of glycerin needed to preserve the plant
material as the alcohol evaporates off. We know that a little glycerin
is good for pressed flowers since glycerin is in the fabric softener
that we use so it seems this should be workable.
A good way to
treat certain materials before pressing is to put the anti-freeze in a
To lessen the
ratio of glycerin to alcohol, simply add
some extra alcohol or water. I'd recommend no more than a teaspoon of
glycerin to a pint of water/alcohol.

use care and make sure your spray bottles are clearly marked.
