new unglazed quarry tiles

Dear June,

the firsrt you must put them in the oven about 300 F about an hour and then rise temperature to 500 F about half hour.If you do not do it that way that the tile will break.When you clean them,first let them cool down and wash them with warm water,if there are some parts of the bread that just scrape it of. DO NOT USE ANY SOAP because the soap stay in the tiles and when you put the bread on the that the soap will go to the bread and you do not want to have soappy bread.
