Unused cutting boards cracking along glue lines.
Hello. I made quite a few cutting boards a while ago but i never got to properly finishing them as i had to move countries. I stored them in a dry area away from sunlight. Im back in town today and i looked them over and 2 of them (so far) have cracked along their gluelines. One of them is made out of oak (i know its not ideal for cutting boards), and the other european beech.
Im really curious how this couldve happened, i glued them using titebond 3, they were untreated, so no oil but they were also not stored in a humid area.
Ive sold 3 from this batch back in 2025 and i havent heard any complaints, the plan was to sell these too. But now im a bit worried.
Any ideas how this couldve happened?
