Intro: Flower Crystallization

This instructable explains the basics of fresh flowers crystallization.

One day I have tried to doped a flower in a mixture I use to crystallize objects and impressive crystals have grown on the flower.
After seeing the results, I've been asked by some friends to do some crystallized flowers for their wedding decoration.
Today I am sharing with you my discoveries.

Step 1: Material

- Fresh Flowers
- Alum Salt (also called potassium Alum)
- Water
- Jar
- Kettle or anything to boil water

Step 2: Boil Water

First you need to boil water.

You can use either normal or distilled water. From experience it seems that distilled water make bigger crystals.

Step 3: Dissolve Alum Salt Into Hot Water

Fill half a jar with Alum salt and complete with hot water.

Stir the mixture to dissolve the maximum of Alum salt.

Step 4: Put the Flower in the Mixture

Wait until the mixture temperature goes under 110°F - 45°C
If you put the flower in a liquid too hot it may change the color or aspect.

Then put the flower upside down in the jar and fix it so it doesn't touch the bottom of the jar.

Step 5: Wait for Crystallization

Crystals takes about 4 hours to grow.

The more you wait, the bigger crystals will be.

Step 6: Remove the Flower and Let It Dry

Remove carefully the flower from the jar.
Then let the flower dry upside down.

Once completely dry, crystals will be stronger attached to the flower.

Step 7: Admire Crystals

Crystals will have different shape and size.
The best way to admire them is to go to a place with a lot of light.

Step 8: Video

Watch the result in video.

    It remains beautiful for 3 weeks, much more than fresh flower without crystallization.

    Crystallized flower are fragile, some crystals may fall if you touch them. For a table decoration I recommend to put them under a glass dome to avoid people touching it.

    You can make about 10 to 15 big roses with a pound of alum

    Wow!! This is so cool and should have won the grand prize! Do you think the crystallization would work with sugar?

    Thank you very much.
    The crystallization process works with sugar, but I've never tried it on flowers.

    Alum is very very bitter. You won't have problems with kids trying to eat the flowers. You won't poison the kids either.

    May need to agitate the flower some to disperse air bubbles. This can be a problem with flowers with tubular petals.

    Might be merit in dipping the flower in 99% isopropyl alcohol for a few minutes. This will dry the flower some. Test with one first.

    Other crystals: Salt crystals grow too slowly, and it's hard getting a salt solution above about 30%. Sugar should work, but experiment with the amounts. Sugar is essentially infinitely soluble in hot water. You want a concentration that will still be liquid at room temperature. There are recipes for candied flowers in fancy cookbooks.

    Some similar effects can be done by drying the flower first, spraying with something sticky, then applying a granular substance. E.g.

    Spray with a sugar solution. Let dry a while to get tacky, then use coarse ground demarra sugar. Baking supply stores have coloured sugar in various crystal sizes. You can also use small coloured beads, coloured sprinkles, sequins,...

    Unfortunately I've never succeed to grow crystals on flowers with table salt.

    It is also called potassium Alum. It is mainly used as smell killer into homemade cosmetics or household products. It costs me about 7$ per pound.
    A substitute of Alum salt for crystallization is Borax, but I've never tried it on flowers.
