Seeds not growing; are they still viable?

I have a number of seeds I'm going to try to use some techniques on to see if they're viable. The problem is, I put them in non-soil growing media (steadygrow, etc) and they've been in there in the humidity and head for a few weeks.

The two seed kinds are Baptisia pendula (False Indigo) and Primula Polyantha (Primrose).

While there's no mold on the seeds, will they still viable to even try using hot water (in the case of False Indigo) or chilling at 40-50 degrees (primose)?

To be chilled for pre treatment to germination, the primrose should be at 35-40F, about like your household refrigerator. P polyantha doesn't usually need it but chilling shouldn't hurt the seed either, not even if you've sown them some time back (just don't plunge them into your freezer for an abrupt drop to 0). At what temperature have you been holding the pots - polyantha is said to germinate best at 60-65 and no warmer than 65 - warmer could delay germination. Surface sown or barely covered.

If you will read through this article by plantsman Tony Avent, you'll see that he has taken ungerminated baptisia from the sowing medium and used the boiling water treatment successfully:

My area is in the basement, but the seeds have heating pads and domes over them, so most likely, probably in the 70's.

Thanks for the link! I'll have to try that out later today.
