Your experience sounds about right. A bit of stirring and patience is
all you need. I let the solution sit (in a dark drawer) and reheat in a
microwave and stir every 15 minutes until it's dissolved. Takes a while
but eventually it all goes into solution. Try to avoid boiling in the
microwave. For small quantities like that, 15 sec. on high is usually
enough for average ovens.
Hope this helps!
