This is the easiest way to root violets that I know. I have rooted hundreds of violets using this method.

Violets like to be watered from the bottom, as a rule. They don't like water on their leaves.

Aluminum plant, I am not familiar with. I will have to look that one up.

Good Luck!

The soil needs to be damp at all times.. watering from above or below just keep off leaf. the leaf does not "germinate" but forms roots then a plantlet will form. There are many variables did youse rooting hormone. temp light fertilization after roots form etc..... expect 3-9 months to have sizeable plant.
