well, what you don't say is whether this is being cased in something else or not.
3% of anything is lots, not so much because of it but because of the necessary changes in percentages that occur in the other additives just based on the simple math.

If both the interior and exterior glasses are in the same base, a simple pull test should show you the difference and if your additive stuff is lower expansion, then add some flux.

The stones are a different matter, but it's not the selenium making the stones. I suspect calcium in the Sp87 would make them though. I just don't know whether SP87 figures into this.
