Does compounding require Identity?

[+Oltux72]

We have seen that any matching Ferring can use an unkeyed metalmind. But what about the Mistings? If you are just a Misting can you compound an unkeyed metalmind? Does it work if you are a natural compounder of that alloy (even if that ability is not very exciting)? Does it work at all?

Unkeyed metalminds can be used by any ferring of the corresponding metal, like Wayne could use that goldmind they found in BoM. However, a misting can’t use these. The type of metalmind anyone can use is an unsealed one, like the medallions. 

This WoB states that an Augur could compound health with a goldmind in the right circumstances:

Could an Augur Compound Health out of a goldmind if its proper owner messed with Identity in the right way?

This is possible

This makes me think that using an unsealed metalmind for compounding is possible.

(There may be a more specific WoB for it but I’m not sure and haven’t found it if there is).

You could probably burn the Feruchemical store. However, this would be of limited use as you couldn’t store it. Unless the store was Nicrosil...
