Red Star, Faultless, Argo, Niagra, etc are all the same; powdered corn laundry starch one makes up several different ways.
Normally such starches were made as one makes a roux, that is a starch and water solution was cooked on top of the stove and or boiled. Once ready the starch solution was used either straight and hot (heavy starch) or diluted with various amounts of cool water to make medium to light starching. Heavy starch would be for such things as nurse's caps, men's dress shirt collars and cuffs, detachable collars and cuffs, and the fronts of men's formal shirts. Everything else used various amounts of diluted starch.
The purpose of cooking the starch was to help break down the starch so it would penetrate textile fibers easily and not just rest on top of the fabric. Excess starch on top of fabrics leads to the iron sticking, scorching, yellowing, flaking and items going limp (shut up Toggle, *LOL*)soon after starching. Starch cookers were once part of every commercial and large on premise laundry, but with the advent of liquid starches and spray starches they are found less and less. However all things being equal cooked/boiled starch used hot will give better results than liquid starch, and both are better than spray starch.
One can make one's own spray starch by making up a batch of cooked starch and diluting it, however it will go bad if not used within a few days.
Satina:
Laundresses and other laundry workers long had discovered various additives to starch gave better results. Satina is nothing more than packaged "wax". Small amounts of wax, paraffin, petrol, soap, fat, and a few other substances when blended with starch make for easier ironing,less sticking, and a more glossy finish. Today one will see "ironing aids" listed on many starch labels, which can be any of the above or silicones.
Bluing was added to starches for whites and light colours. Tea and coffee for ecru and tan linens. There was also perfumes for scent (Faultess still sells perfumed starch) as well.
Yes, can well remember when nurse's caps had to be starched, though many models soon came out in cardboard to lessen laundry day work. Nun's coiffs and such also were starched.
Powdered starches tend to be harder to find in the North of the United States, but once one crosses the Mason-Dixon, things are different. Mainly due to the hot and humid climate, residents of the South love to starch the daylights out of things, especially shirts and jeans. Have seen jeans in Texas starched so heavy they stand up by themselves.
