Excuse the newbie questions.
A small historical society owns the building where a former foundry was located. This foundry existed under several different names from the 1870s to the 1970s. They would like to outfit it with some basic tools to teach the public about sandcasting.
What type of flask would be most appropriate for which era: wood, steel, or aluminum? I believe it's safe to assume that wooden flasks appeared first, with steel flasks introduced later, and then aluminum. As each new material was introduced, the previous was not entirely abandoned, but rather saw continued use. So, a small foundry from the 1960s may have had all 3, whereas one in the 1920s would have used only steel or wooden flasks, and a foundry from the 1890s would only have had wooden flasks? Correct? Anyone know more specific dates?
How about steel or brass molders sculpting tools.....?
I suppose they really must decide which era they're attempting to portray.
Thanks
