I Originally Purchased These To Melt Scrap Silver. I Use My Oxygen Acetylene Torch With A larger Gas Welding Tip (I Hate Waiting On A Furnace) I Found You Can Melt (With Flux Added) About .750 Ounce Troy Of Silver With No Problem. I like Using These Crucibles Because They Transfer Heat Fast And Save Me On Gas And Oxygen Costs. The Recommended Use Is One Time, I Use Mine Until I Break Them. I Usually Drop Them. They Do Not Bounce Well!
Remember: Always Wear Eye Protection And Adequate Safety Attire When Working With Hot Or Molten Metals. Molten Metal Can Blow Back When Poured Into Molds. I Assume No Liability For Misuse Of these Crucibles. Use Them As You See Fit. Thank You.
