Daguerreotype Mercury Pots

Much of this year has been spent in a big learning curve about stainless steel and electrical heat engineering. The goal was to come up with a design for a Daguerreotype mercury pot to be made commercially available for sale, based on my experience as a mercurial daguerreotypist.

In the design I wanted to avoid having a removable mercury cup as some designs as I agree with those that say it is unsafe. I wanted to maintain the popular 19th century design of the inverted pyramid as it presents the best shape for the condensing flow of the mercury to return to the reservoir.

The pot has a telescoping stand so it can be used in the field where you might not have access to mains power and need to heat it with an alcohol lamp. In that case there is a battery powered temperature display to monitor the mercury temperature. When using the electric heating, it is controlled by a P.I.D. temperature controller that is a detachable enclosure. The platinum resistance temperature sensor is locked to the internally capped insert tube.

The pot is finished with a hammer finish paint application and has clear acrylic walls to buffer the rush of cold air experienced in fume hoods.

Two cost options:
1. 8×10 double darkslide mercury pot with clear acrylic walls on its telescoping stand, also with:
-temperature sensor
-AC electric heating system
-battery powered digital display
= US$2950 (incl international shipping)

2. 8×10 double darkslide mercury pot with clear acrylic walls on its telescoping stand, also with:
-temperature sensor
-battery powered digital display
(heating via alcohol lamp – not included)
= US$2465 (incl international shipping)
