These old Early American Pattern Glass bowl were made around the 1850-1880s, possibly by the Boston & Sandwich Glass Company. They have not been positively attributed to a specific glass company. To me they seem to have details similar to known B&S pieces, but they are not in the EAPG database for Boston & Sandwich, and since they cannot be guaranteed as to maker, they've been put in the "AKA Loop" catagory. They are flint glass, and have a nice tone. The pattern is aka Loop, Elongated Loop, or possibly Leaf. Both are the same pattern, being sold individually.
