The IPTW every year brings together some of the most interesting individuals from all corners and all walks of life. Dr. Butler is a great man, hailing from England, and comes to the conference every year. I was fortunate enough to meet him last year at the conference in Pennsylvania but wasn’t able to sit in on any of his demonstrations since, as a demonstrator myself, had a full schedule of my own. This year however I was able to make it to one of his seminars. Internationally acclaimed, he is one of England’s leading and most respected historic brickwork consultants, master brick layer, author, and educator. A true artisan and a passionate preservationist, I admire his depth of knowledge and his level of skill. Not to mention, he has a great sense of that English Humour. His demonstration on authentic mortars hails from starting with two simple ingredients, oyster shells and lime. The chemical compositions and reactions are a must know in order to better understand formulations and compositions of lime plasters.
