I was wondering if anyone out here will tell me how cloth is weighed. I.E. does “4 oz cloth” mean 4 oz per sq yard or 4 oz per sq foot or what? I don’t have an accurate scale or feel like cutting up cloth just to answer an easy question…also is that surface area per weight, weight a standardized thing in the textile industry? I want to try glassing with some other cloth combinations and would like to figure out what oz cloth I am using. Thanks…
Im pretty sure 4 oz glass is not the actual weight of the glass…but how much resin it will take to squeege a square yard of the stuff… so you would mix 20oz of resin to cover 5 square yards of 4 oz glass…im pretty sure thats what the weight meens… happyglassin
In australia it is grams/square metre. 1oz = 28.35grams.But we still call it 4oz, 6oz etc.The only way to tell is to weigh it or go to a supplier or glass shop and ask.They should be able to tell you by looking at it. Hope this helps,David.
In the US it’s by the square yard. Sometimes they round it off, as in 3.7 being called 4 but it’s per square yard of fabric.
It’s what the cloth itself weighs in ounces per square yard, though for some types of cloth ( sailcloth in the US, for instance ) that yard is 36" wide and 28" long. I’m sure there’s other oddities in cloth measurement. And if you were to buy 10 yards of 10 ounce cloth and weigh it, it might come in at 50 ounces or more, on account of the width being greater than 36", the weight of the cloth being gauged before they added surface treatments like Volan and so on and so on. Hey, look, the textile biz is an industry that just got away from using ‘ells’ and such in everyday commerce. Distinctly odd gauges for thread size that vary with the type of material and such. I’ve been moonlighting doing boat canvas and such - amazing what a mix of technologies there are still in use. Don’t ask what a ‘denier’ is. doc…
