The Roman mosaic I fumbled with a garden hose in my own backyard
So I found this loose tile in my garden in Bristol about 3 months ago, and I got all excited thinking it might be Roman (you know, because of the Bath connection nearby). I started digging around it with a trowel, real careful like, and I uncovered a small patch of what looked like a real mosaic floor. I was so stoked I called the local museum and everything, and they told me to keep it damp and wait for an archaeologist. But then I got impatient, grabbed my garden hose to spray off the dirt, and I blasted the thing at full pressure. The water hit that old mortar and the whole section just crumbled apart into little pieces right in front of me. I felt like such an idiot standing there with the hose still running. Has anyone else accidentally wrecked a find by using the wrong cleaning method or tools?
