ANOVA to compare difference of means?



I prepared a solid material using two different methods (factor 1; 2 levels) at six different temperatures (factor 2; six levels). I repeated the procedure three times for each condition (3 replicates). I characterized the solid obtained by experimentally determining its quantitative property A.

I would like to know how to determine at which temperatures both methods produce a solid with the same property A and at which temperatures both methods produce solid with different properties A. (Alfa = 0.05).

I thought that I could analyze with ANOVA the difference of the means, but then I got lost ...

I would appreciate very much someone suggesting me how to evaluate at which temperature both methods produce the same/different solid material.

Kind regards!
