blue is just the Hydrated form of it.

if you make the brown/yellow, it will go Blue as soon as you mix it with water

the excess HCl will indeed be driven off with gentle heat, although you MUST do this either outside or in a suitable fume cupboard else every bit of metal within that room will corrode (including circuit boards and TVs!).
you May also end up with some HCl Locked up in the crystals themselves, this isn`t a good thing as it`s then quite a reactive material and will make unstable certain pyro comps.
unless you NEED it ASAP, I suggest you hydrate the lot into the Blue soln and store it until you Can get more carbonate.

in that case it`s not a problem, you may even get some further chlorination take place with a few of the more volatile organics in there that should act towards being a Chlorine donor too
I have to ask though, I know about the pine cones on a fire to give the color, but what do you use the sawdust for?

sure, the reaction proceeds as such: CuO + HCl --> CuCl2 + H2O.
but the carbonate will be cheaper I think.

strontium chloride and magnesium sulphate will react, making strontium sulphate and magnesium chloride.
the same will happen with barium salts too, in fact barium salts are used to test for Sulphate.
try just the SrCl2 on its own, and if that doesn`t work it`s the pinecones at fault.
