My family and I lived in a house on Wopsononock Mountain that we rented from 1972-1979. In 1979, we moved to the house we built with one house between them both. A friend used his bulldozer to level and grade all three backyards. Soon after, each rainy day uncovered hundreds of white hotel dish shards, disturbed for the first time since the 1903 fire that destroyed the hotel.

Extra time to search for artifacts was rare that year we built the house but I was lucky to find two near-perfect porcelain doorknobs* and one doorknob, burned black, perhaps a previously painted one. I also found one complete piece of hotel china, perhaps used as a soap dish or a side dish in one of the dining rooms.

*From a Google search: Finding porcelain doorknobs that survived a fire is not uncommon, as high-quality ceramics are fired in kilns at temperatures ranging from 1,200°C to 1,400°C (approx. 2,200°F–2,600°F) during manufacturing.
