About

Kettles - copper causes premature kettle failure.
Kettle manufacturer - [1]
Materials engineered for use in galvanizing operations - the specific property required is
Wikipedia - [2]
Zinc Ammonium Chloride - used as flux - [3]. Zaclon in Ohio makes it. [4]
Coating thickness for 1/4" and above steel is 85 microns minimum. [5]
Kettle inspections - tests wall thickness - apparently for wear and complete loss of metal. Wall thickness is measured ultrasonically in situ o a working kettle with molten metal. [6]
Melting zinc - you can even melt on stovetop, here is a tiny wad of zinc melted into a mini-ingot [7]

From [8]

Sand blast
Base bath - 10 minutes min
Base bath - 7 minutes min
Flux - ammonium
Actual dip - 3.5 minutes (until base metal reaches melt temp of 835F)
Water - trapped water explodes, and is dangerous, so first dip is dangerous and venting must be assured.
Zinc - 2400 lb blocks are the feedstock for hot dip baths. This is only 0.1 cubic meter - or 4 cubic feet.
