Most bricks are made of material known as magnasite. The magnasite has a shelf life of about one year. If you have bricks that are made of magnasite and they are older than one year you risk the chance of them falling apart. There are newer bricks being manufactured that are composed of polyesters. The polyester bricks have no shelf life and will last for several years.
TIP When purchasing magnasite type bricks, ask the distributor how long the bricks have been in their inventory. If they have been in their inventory for more than six months I would refuse to buy them.
