15% H₂SO₄ is really pointless. You might use it to generate 15% other mineral acids, such as HCl or HBr that you can then distill to azeotropic concentration. But other than that…

Sorry I had no time to try the oleum synthesis this time. I did buy a 3 kg pack of sodium bisulphate for a song (like 3 €) and I'll see next time if I can generate SO₃ out of this, using a quartz test tube and a blowtorch.

I would try the lead chamber process. An SO2 Generator an Gas washing flask with nitric acid and after it an big flas for the acid reaktion.
