"Freezing" Tiberium?

[Pam]

I've never had the display case produce any kind of Tiberium at all, much less a small spire cut!

If you place a mixture of metals and gems of a total worth between 3500 and 5000 on the display case, you should get tiberium.

We had a member that did extensive testing and came up with this guide for us to use

MIXED TRANSMUTE

If you combine separate types of items (gems, metals, relics) you get a new item based on the total value of the items transmuted.
