The site environment is an important factor in determining the condition of artifact material. A thorough analysis of the site environment has not been completed, therefore, the condition of certain material types can only be predicted through past excavation experience. The anaerobic mud in the St. Johns River is oxygen free slowing down normal deterioration processes. Preservative qualities, however, do not extend to all material types equally. Inorganic materials, such as ceramic and glass, are well preserved. Metals exhibit differential corrosion based on type and proximity to a dissimilar metal. Tinned iron contains two dissimilar metals and is a good example of poor preservation.
There is very little biological activity in the sediment leaving many organic materials well preserved. Wood, bone and antler are durable materials that survived well. Other materials rarely found on archaeological sites are abundant on the Maple Leaf. They include leather, fabric, rope, and preserved foodstuffs. Wool, silk, and possibly linen fabrics survive better than cotton fabric. Acidity is probably responsible for this and may account for the absence of paper. High rag content paper, common during the 19th century, should be plentiful but only a small scraps have been found.
