Antique Bottle Types
These are a combination of top types, and design features that allow for quick field classification.



Screw top
Some early glass blowers made screw tops during the 1860ís, but the standard thread screw top was not common until 1924. The vast majority of screw tops found will be these common 20th century versions and do not have much value. Early screw tops can be distinguished from automatic machine made screw top bottles because they will have a rough ground lip and will not have a mold seam that runs through the lip.

Painted Bottles
Applied color labels or lettering (ACL) replaced embossing on most soda and milk bottles. Painted bottles were developed during the early 1930ís. They were more cost effective to produce and the bright colors enhanced point of sale marketing efforts. These bottles are most often machine made crown tops, screw tops or milk bottles.


Crown top
Crown tops were invented by William Painter in 1892. These bottle tops require a bottle opener to open. Crown Tops can be found as both applied tops, which can date to just after 1892 or machine made. By 1915 most manufacturers had switched to this style top. Crown tops lasted through the 1960ís when screw tops began to replace them. Crown tops are most often seen in soda and beer bottles. The most collectible of these will be the older heavily embossed applied crown tops and some ACL bottles.

Blob top
These bottles have a blob of glass applied as the top. The blob was applied after the bottle was removed from the mold, and then hand =tooled to form the top. Most often found on soda and beer bottles some are highly collectable. Their value ranges depending on color, condition and how elaborate the embossing. Blob top BIM bottles date from 1840-1890.



These soda bottles had a metal hook and rubber gasket sealer. They were designed to contain the pressure of carbonated drinks. Hutchinson bottles date from 1879 to 1912. These bottles are very collectable. Colored versions, highly embossed and bottles from certain areas are more valuable. As a general rule East coast bottles are more common and less valuable than those produced further to the West.


Lightning type
These bottles have a porcelain or hard stopper which is latched with wire over the lip of the bottle. These were produced just after the Hutchinson style. 1880-1900 mostly commonly used for beer bottles.




Bromo Seltzer & Milk of Magnesia
These cobalt blue glass bottles are very common, and have little value. That said they still look good on the shelf. Note the barnacles left attached to bottle adds a little character and makes it immediately identifiable as being recovered from the marine environment.

Unlike other books on the subject, that provide a diagram and step by step instructions Capt. Dan attempts to teach model builders to understand the basic principals involved. After reading this heavily illustrated text, readers should have a good understanding of how to design rig and build both square sailed as well as fore and aft rigged vessels. They will then be able to apply the basic principles and techniques and build any type of sailing ship they choose. Please note that there are many different techniques used by different builders in creating their ship models. Some use elaborate mast hinges while others contend with a maze of rigging lines which all run through and under the hull. This book teaches Capt. Dan's basic and the straight forward simple techniques that the authors uses on all of his ship in a bottle models. These basics can be enhanced and modified as model builders become more proficient. Capt. Dan has included a showcase of ship in bottle images from some of the best master model builders in the world. Often the best way to improve skills and technique is to examine the exquisite work and detail of these masters.

Capt. Dan has heavily illustrated this text with over 200 color images depicting the types of bottles that can be recovered by searching local waters. He also uses over 10 unique 3D diagrams designed to give a better understanding as to the time line of glass blowing and bottle manufacturing. These 3D mold images are combined with drawings of the bottles they produced and highlight the distinct mold seam marks each created. This informative text tells all the tricks of the trade that until now have only been learned through years of experience. Bottle collectors, scuba divers and anyone interested in exploring the marine environment for these historic treasurers will reference this text often as they search for and collect antique bottles.
