Yes, mines used by the Confederates were indeed made up from every possible source the Cofederates had at had, but my comments were about the paticular mine that was taken from the Bayou Teche that was manufactured in New York. I offer that section from the New York Times article, "The Banks Expedition," January 31, 1863 below and also a bit of information about mines in the next article below the Times article:

The Torpedo Incident

Before closing my narrative, I ought to say that the information which our good friend, the contraband from the Cotton, gave respecting a concealed torpedo, proved to be perfectly correct and exactly where he stated. I saw this infernal machine on board the Estrella, and afterward conversed with the poor fellow who rendered us such essential service, and who is now safely in our lines. Judge of my astonishment when, on scraping away the waxen stuff on the brand of this machine, I discovered the following inscription in raised letters:

TAYLOR & HODGETT’S CANE
With Burnett’s Attachment
New-York
Patented Aug. 21, 1855.

It was shut up in a neat wooden box and labeled in large letters, “Hospital stores—this side up, with care.” The manufactures are fully welcome to all the benefits of this advertisement. “Hospital’s stores,” forsooth! Rather a grim joke, is it not? One strange thought struck me as I gazed upon this monstrous invention, and that was that while people in the North are enriching themselves by manufacturing these hellish things to blow our own bare men to atoms, a poor black “animal” down here has friendship and humanity enough to come and warn them off from their terrible doom. I forgot, in my hurry, to write down this Negro’s name—perhaps it is as well I did not—Gen. Weitzel can easily find him; and surely, if the lives of some dozen or two of our defenders are worth anything, that faithful fellow should not go unrewarded.

The earliest land MINES were called torpedoes. The first of these were devised by Confederate Gen. Gabriel J. Rains during the withdrawal from Yorktown in May 1862. These torpedoes were improvised from 8- and 10-inch COLUMBIAD shells and were condemned by leaders on both sides, who called them “INFERNAL MACHINES.” Nevertheless they were adopted by both sides. Later uses focused on floating torpedoes to obstruct waterways. Some of these were anchored just beneath the surface of the water, set to detonate on impact, and others were monitored to be detonated by lookouts on shore. One version of the former was known as the RAINS TORPEDO, which was fashioned from a small beer keg suspended between two wooden stabilizing cones. It was detonated by a trip wire attached to its anchor. (Source: Webb Garrison’s Civil War Dictionary, by Webb Garrison Sr.)
