Early mortars in North America are commonly a mixture of two or more ingredients: lime, sand, clay and portland Cement. By analyzing the mortar, identifying its components and measuring the ratio of in-gredients, it is possible to differentiate between seemingly simalar mortars. If we know the mortar-making practices of different periods a building may be dated with fair accuracy if the mortar is identified. Also, it is necessary to establish the ingredients of a mortar if it must be repro-duced for the restoration of a building. An easy method has been developed to analyze mortar samples on the field with a few simple utensils.
