When you mix up the slurry you need to introduce the beeswax gradually. Otherwise it may not be properly emulsified. In the final concoction there will always be tiny bits of undissolved wax in the final mix, which I would call more opalescent than opaque. White gesso is opaque.

Yes, I mixed up the Gamvar a couple of days ago... but perhaps I rushed the slurry mix and the wax isn't sufficiently emulsified? Or maybe the whole thing just needs a couple of days to settle now that the bee's wax is mixed in? Opalescent could
maybe describe what I've got, but so could murky... Certainly not so opaque as white gesso! I'll give some more time and agitation, and make sure it's warm enough -- then see what it looks like on a painting!
And Marvin, I will use glass to make the slurry in next time--Thanks!
