The Framers Forum

Thank both you for the history. This frame has what appears to be a thin gesso layer underneath the paint. When did they first start this process?

Two questions. 1.What is the joint termed on the let in miter and the origin of it? 2. When were keys first introduced in stretcher bars?

Thank you.

Thanks Vintage framer and Not a framer. I have learned something. Thanks again.

The panel is very thin at 1/8' . Most panels I am familiar with are 3/8" or thicker. Trying to date the panel.

Thank you. Was either wood used in the late 1800's?

Another question is board. I have a painting on 1/8" board which appears to be birch. Do not believe it is plywood as it doesn't appear laminated. At what period in time would such material be used?

I had figured that sealing the back had a purpose. Thanks for all the input.

I have a couple of 19th. century paintings on wood panel. On one of these paintings the back of the board is painted black. It is not the first time I have run into this. Would there be a reason for this? My thoughts were to seal the back, or perhaps to hide something. To hide what I am not sure. Ye...

Experimenting with a little frame restoration for myself only. Always nice to learn new things.
