...what are the chances of poisoning myself using such a cutting board from the glues used in veneering in the 1920s?
Thanks

Hmm. 50/50? 60/40? 100 to 1? What chance are you wiling to take? My guess is they probably used hide glue and is therefore not toxic.

Mahogany is not a great species for cutting boards because it is so porous—- but the glue should be safe.

From the 1920’s it is very likely that they used hide glue which is not toxic but would come off during washing of a cutting board. Based upon my research, I think that chemical glues where not widely used until the 30’s. One advantage to using hide glue is that the joints can be “unglued” or reversed with heat and moisture. Look for info on restoring turn of the 20th century furniture for techniques. The veneer was probably also attached with hide glue which can be easily removed with heat and moisture.

Another feature of hide glues is that the joints can sometimes be broken using shock with a sharp blow from a mallet or using a chisel to split a joint. Mortise and tenon joints are tough with either heat/moisture or the shock method so require considerable patience. If you are not trying to repair the furniture, you can simply saw them apart and leave the tenon in the wood as a plug.

But if it really is mahogany, I would find a use for it other than a cutting board.
