Often you can tell what a bottle was used for by its shape.For example, soda water and beer have distinctive shapes that were rarely used for other products.Values of bottles are determined by a variety of factors including age, rarity, demand, manufacture method, advertising and use, glass color, presence of a label, and eye appeal.Unless your bottle has a label or words embossed upon it which can be researched online, the biggest challenge facing the novice collector will be identifying the age of the bottle and its type or use.Iron pontils were solid disk that often left a metallic residue on the glass.Other pontils include sand pontils and glass tipped pontils. Most bottles made after about 1910 were made by machines, but of course many glassblowers continue to make bottles today, so a hand blown bottle is not necessarily an old bottle.These scars were made when the glass tipped pontil rod (which is used to hold molten glass while it is worked) was removed.
Bottles and jars produced between 18 used a lipping or pressing tool to apply the lips and prepare the object for closure.Machine made bottles generally have a distinct side mold seam visible on the body, shoulder, and all the way from the neck and may incorporate part of the lip.Bottles in the period of 1890 to 1910 were made by a combination of techniques ranging from being blown in a mold by hand with the top hand-finished, to machine made bottles that had minor hand finishing of the top.Collecting old bottles and jars can be an interesting and engaging hobby.Antique bottles command a high value, and collectors can make a profit while reselling antique bottles and jars.
The lipping tool applied an additional glass band around the opening of the neck and the glass band was then twisted in place, with the support of two other pieces clamped on its outside.
