Technical Information on

Jars of Frogs



Material List:


Collection jars:

These came directly from the American Museum of Natural History Herpetology Department in NYC
where they contained small reptiles and amphibians most of this past century. These jars were patented May 21, 1895.
At least one of the seventeen hundred I purchased was hand blown into a mold and has a ground glass top edge
where it was originally cut from its punty.


Silicon rubber:

The clear liquid looking material the molded frogs are suspended in is a food safe silicon rubber often used
by the film industry to simulate glass windows that can be broken without harm from sharp edges.


Urethane plastic:

The frogs are cast in plastic (sometimes rubber) that can either contain or be coated with a
phosphorescent ultraviolet receptive material.


Phosphorescent materials:

The glowing effect is achieved through a variety of nontoxic phosphorescent pigments and dyes.
Some are fluorescent so they glow only when exposed to ultraviolet light.
Others are phosphorescent so they absorb ultraviolet light and release it slowly even in total darkness.
The effect of the combination of these materials produces a variety of effects that varies from jar to jar and frog to frog.


Shipping:

These jars can be packed and shipped with near certainty of no breakage.
For shipping prices please contact me with your location including zip code.


Edition:

This series is limited to 94 signed and numbered jars and a small series of artist proofs
as thanks to those who have helped with this project.
