Fig. 7From: Optimizing the thermal treatment for restoration of brittle archaeological silver artifactsThe optimal conditions for thermal treatments. a Results of simple bending tests after comprehensive thermal treatments were carried out (○: the samples break without being able to withstand one bend, ◐: the annealed samples can withstand one bend without breaking, ●: the annealed samples can withstand two bends without breaking). b Temperature–time map (T-t) summarized through the results of the simple bending testsBack to article page
