Sea Glass

Generation:

• Can be found exclusively in the Oceans
• Usually generates on the sea floors and/or the sea caves,but can also generate near the shores sometimes.
• Usually generates in "packs" of 4-5,but can be found individually.
• It's common on the sea floor.Not as common as coal,maybe a bit like iron,but still decent.

Description:

• The ore has multiple colorful spots on it
• Drops 3-6 Sea Glass Shards normally,up to 30 with Looting III.
• Can be used to craft Sea Glass Block,that is rainbow in color and semi-transparent (in a way that,you could see trough it,although it'd be a bit cloudy).
• It's other major use would be as a "Rainbow Dye" of some sorts.You can use it to dye glass/glass panes into Rainbow Glass/Rainbow Glass Panes,Wool/Carpets into Rainbow Wool/Carpets,make Rainbow Beds,Rainbow Banners,Rainbow Stained Clay,etc.

This ore was inspired by an actual "mineral",https://en.wikipedia.org/wiki/Sea_glass,but since this is Minecraft,I had to "accommodate" it to the said game :)

In general,this'd add some rainbow fun into the game,and would make the Oceans even more beautiful and worthy of exploring! Plus:More ores! YAY!
