White Crystals (No Geodes just spawns in caves)

These would be in clusters, like on the ceiling of the new generation, and could be used for dye, salt (for new food maybe?) and can be used for a light source. This kind can be picked up with silk touch and does not spawn in geodes. Also could be used for White Crystal Blocks, which also emits light. And if they add color to lights, emits white color! and could also be combined with tinted glass and Redstone for a flashlight. Which emits light and has a chance to kill mobs when first pointed at them. maybe they could even be used for batteries and you have a battery charging area, and you use that to make flashlights and you have to recharge them. but they don't break. And new enchantments for them as well. it would also be cool if they were in the lush caves as well with a little green on the top. just a little look change. Also could be used to make sugar. And other things, in the comments! :D
