Create crushed ore issues

[MarioSMB]

I've noticed a couple of minor inconsistencies with the Create compatibility crushed ores:
They can't be smelted into ingots, and washing the crushed ores doesn't give any byproducts (for example, when you wash crushed gold ore you have a 25% chance to get Nether quartz).

As a suggestion, I think washing crushed silver could have a chance to give an emerald as a reference to its value in the real world. Lead is a bit harder - maybe lapis lazuli as a reference to lead's blueish tones when freshly cut?
