Metals class introduced us to the art of blacksmithing as well as the deterioration and preservation of various metals. Jeff Forster, guest instructor, owns a decorative ironworks and metal restoration business in Wheeling, WV.

Our Field Lab class in Morristown, OH gave us the opportunity to carry out sandstone foundation repairs. Improper face-bedding of the stone as well as the use of a Portland cement had caused some noticeable deterioration of the stone. The joints were repointed with an appropriate Virginia Lime Works mortar and one significantly damaged stone was given a plastic repair with a Jahn restoration product so that its cavernous face could be made sound again.

In Windows & Doors class, damaged sashes and sills were removed from an 1880s one-room schoolhouse in Pleasant Hill, OH for repairs back at our lab space. Repairs included documentation of conditions, wood consolidation, paint removal, and re-glazing. Our final project was the creation of a paneled door with traditional mortise and tenon joinery and raised panels.

Graining & Marbling Class introduced us to the art of faux painting. Projects included sample boards of various stones and wood species. Final projects involved the creation of a “Pietra Dura” panel or stone marquetry as well as a panel with a graining and marbling combination.

And finally, my advanced material science class, which I elaborated on in my last blog, involved the conservation of structural timbers. Various techniques were carried out, including: splices/ dutchmans, WER (wood epoxy reinforcement), as well as mechanical repairs.
