The urban legend that bad things will happen if you mix silicone and glycol fluids is still around, I see. NOTHING happens. No atomic fusion, no explosion, no "goop" formation. I have done it myself in a glass jar. They don't mix (the silicone floats on top the glycol) but there is absolutely no reaction. If you wait long enough, the purple dye in the silicone will migrate into the glycol. That's all. The fluids still don't mix.
