I have an 1850 salt tin image that is in a window of an old railroad A&W cook stove, however, I can see him pretty clear but, I don't know who he is and, I don't want the picture destroyed. The stove has three small arched windows made of some type of fire proof plastic and, the picture is in the middle. Can you help? The stove has a date 1883.

Suggest that you consult an expert in photographic conservation familiar with rare 19th century photographic processes. To preserve the rare image, you will want to avoid light exposure to minimize fading of the image.
ReplyDeleteNot sure what you mean by "fire proof plastic." Not aware of any 19th century clear or fireproof plastics. "Eugene Sullivan and William Taylor co-invented Pyrex in New York City. 1916."
ReplyDeleteFire proof plastic in that era is probably mica
