Autumn Nature Study Special Studies

Preserving Autumn Leaves

Last week we considered the Chemistry of Autumn, and tried to preserve some of the best colored leaves for our nature study wall/shelf.

First, we collected the most colorful leaves we could find – on our property.  We saw some prettier ones while driving down the road, but I decided that it was more important that this be part of our collection of leaves from our own property.

Then we prepared the recipe in a baking pan:
1 part glycerine (found at a local pharmacy)
2 parts water
We laid in a few of our favorite leaves from different trees, loosely covered it with plastic wrap, and then set a smaller baking pan on top to force the leaves down into the liquid.

 

We started checking them after a couple of days, wanting a supple feel, and then we blotted them dry when they were done.

If you compare the before and after pictures above, you can judge how well it worked.  The Tulip Poplar leaf turned out real nice.  The green colored Red Maple leaf kept a nice green color, but the red colored Red Maple leaf, didn’t keep its color.

It seems that leaves displaying a splendor of yellow and orange, might be the best for this technique, but the leaves with red don’t do as well.
