Feruchemy Metal Symbols

[Newly Awakened Spren]

I was looking at the Feruchemy metal symbols and the dice for the Mistborn Adventure Game have two Bronze symbols (red) and the two symbols I don't know (blue and yellow). Can anyone tell me what they are?

The blue one is Harmonium, the yellow one is Malatium (the 11th metal).
