Frozen roses can be used as an element of the interior of your apartment or simply as a reminder of romantic moments in your life. Freezing a rose is not difficult, but the whole process will take quite a lot of time. In order for your frozen roses to delight you with their appearance for a long time, you should strictly adhere to the instructions for dry freezing and use special equipment.
It is necessary
Several roses, apparatus for dry freezing (sublimation machine)
Instructions
Step 1
Separate the rose petals. You can freeze a whole rose and stem, but this process can take much longer and lead to unpredictable results. It is recommended, however, to freeze only the petals.
Step 2
Place the petals in a dry freezer and set the temperature to -7 degrees Celsius. The rose will be frozen in a vacuum space, which will greatly speed up the freezing process.
Step 3
After completing the freezing process, set the normal (room) temperature on the device, which will gradually return to a new temperature state. The rest of the process, called "sublimation", will take about two weeks. During this process, the water contained in the petals turns into a gaseous state, which allows the color and shape of the petals themselves to be preserved for a long time.
Step 4
Store frozen rose petals in a cool, dry place or in the refrigerator.
