Well I'll tell ya, you did a fabulous job with More Materials. I love it!
I actually haven't played with Alchemical Reactions yet as I discovered More Materials as I was migrating from 1.6.4 to 1.7.2. I was so sad when I found Alchemical Reactions was still 1.6.4. It was awesome to find that you're updating it. Can't wait to add Alchemical Reactions 2 to the list of mods that I am using. Really looking forward to it.
