    I also wonder about the cost of using the oven, and whether it’s cheaper than just buying washing soda.

      P = = oven average power ~1kW=1/1000MW
      C = = electricity cost ~50 to 200 $/MWh
      Δt = = process time duration ~1.0h
      Total = P x C x Δt
      … so, a few cents maximum, right ?
      … it’s more the time and effort you put in !
