According to REI I can either use 4 tiny platinum dust to make a platinum dust * or * 9 tiny platinum dust to make 1 platinum dust.

Also REI shows a platinum dust to platinum ingot in a furnace * or * platinum dust to Electric Blast Furnace (Kanthal Coil Tier) to hot platinum ingot then hot platinum ingot in a vacuum freezer to platinum ingot. So either 2 steps or 1 step to take the same thing and make the same thing by the end. Which do you think I'd chose, right, furnace, not EFB, faster and easier. >.<

This is the 1.6.1 version of AOF6.

Update: Just updated to 1.7.0 and problems still exist.
