I didn’t take a picture of the result as it just failed to mark anything
I think the mustard layer was too thick
I’ll try again with thinner layers and let you know how that worked out, but it’s far too late now and I think I already lost a part of my mind in this
I also had to google how to make mustard gas and whether it has something in common with mustard (hello terror watchlist here I come) to make sure you are not gassing yourself by accident:
Sulfur mustard is more commonly known as "mustard gas’'. This name "mustard gas"was first used when the chemical was sprayed during attacks in World War I. Sulfur mustard has nothing to do with mustard but gets its name from the yellow color and odor of mustard it may take on when mixed with other chemicals.
in our house, we tend to prepare it with a balsamic vinegar sauce and salsifis
In France, supermarket mustard comes in little glasses with illustrations for the kids.
i think every child here has had his own favourite mustard glass (s)he used for years ^^"
I’ve seen this one, but they advised to make a first pass to “carve” a little pocket, and then make a “fill” pass with the powder added
Also, it seems making a “line” operation afterwards helps with getting a good result
I don’t have epoxy powder at home right now to test it out though
Actually I was thinking about something similar for copper
My wife has many of the required products as she made a few copper etching for letter press…
Another way to go at this would be to apply vinyl to the Steel, cut the design, remove the inside and etch it with saline water and electricity
