I've no idea if they are the same thing, but way back when I was in FFA, the guys who showed pigs used to get this stuff called "gridle brick". The intended use for this stuff was to clean the big gridles down at your local diner. It worked great for scrubing those long, ugly and unruly hairs off of the pig's jowl (gently though boys, that stuff'll wear a hole quick!), in prep for the stock shows. Anyway, this stuff had some sort of sulphur base....or something, 'cause when that brick starts coming apart, boy you better be outside.......smells like a bad night of beer and eggs. gar
