Forgot to comment on this.  The high viscosity is a sure sign of cold
epoxy.  The high viscosity makes mixing tough, and "whips" air into the
mix.  Even though the resin is cold to begin with, the exothermic
behavior of the mix will quickly heat it up, foaming the bubbles and
creating a hell of a mess!

Probably the white appearance is due to bubbles in the resin or maybe
"outgassing" from the wood.  Hard to tell without more info.
