To date glass, examine its manufacturing method, mold seams, and maker's marks. Look for rough pontil scars on the bottom, which indicate pre-1860 hand-blown glass. Modern mass-produced glass made after 1910 will feature smooth finishes and mold seams that run all the way over the lip.
Not all Fenton glass has a maker's mark. Pieces manufactured before 1970 usually only had paper labels, which were easily lost. Fenton started permanently stamping their oval logo into the glass in 1970, though some 1990s and later pieces may still lack marks because the mold stamp didn't press deeply enough.
Type III glass is soda-lime silicate glass, which contains little or no boron. Type II glass is treated soda-lime silicate glass, which begins as Type III glass and undergoes a surface treatment to increase its hydrolytic resistance. Type I glass has the highest hydrolytic resistance.
There are four main types or strengths of glass:
