Laboratory steaming test were designed to investigate the effect of steaming parameters on the colour change of black locust wood at atmospheric pressure. There was no difference detected between steaming properties of material of sprout and seed origins. The results show that steaming can diminish the colour heterogeneity of natural black locust wood. At atmospheric pressure, the effective steaming time was found being four days. After nine days, there was no considerable colour change. Even at atmospheric pressure, it was possible to achieve such dark brown colour for black locust wood that is similar to the colour of some exotic wood species. If a specific colour is desired, the proper process parameters controlling the steaming process have to be set accordingly and monitored closely. The final colour not restricted to any particular region (surface or interior) but is uniformly distributed over the entire cross section. There is no danger of secondary modification by further processing.
