You can't. If you're a member when you mine the essence it is pure essence but if you are just free-to-play then it just comes out as rune essence.
No you can not they have to be unnoted same with Pure essence.
If you mean a talisman, a talisman is an item in RuneScape which, after completing the quest Rune Mysteries, allows you to create runes by having rune essence or pure essence in your inventory, mined from rune essence mines. Left click it to give you directions to the altar. Then, use the talisman on the altar, and click on the stone in the middle. Congratulations, you have made runes. Depending on which altar you went to, you will make runes of that kind.

Pure essence can only be mined by members, above a certain level. Pure essence can also only be used by members for runecrafting. Pure essence is required for the more advanced runes (the runes that can only be crafted by members). For the basic runes, you can use rune essence or pure essence, but pure essence is more expensive, and therefore a waste.
There is no such thing as "Icon Essence" in Runescape. There is, however, Rune Essence and Pure Essence. Rune Essence is acquired by, after completing the F2P quest: Rune Mysteries, teleporting to the Essence mines and mining with either less than 30 mining or mining in a F2P world. Rune Essence is used to Runecraft Air, Mind, Water, Earth, Fire and Body runes. Pure Essence is acquired by, after completing Rune Mysteries, teleporting to the Essence mines and mining with 30 Mining and up on a P2P world. Pure Essence is used to Runecraft all runes, including the ones Rune Essence is used to Runecraft.
