I’ve searched previous posts to find help in melting my 925 silver, approx 12g new from Cookson. I bought the setup suggested before, with the sievert 3941 burner and am still struggling. I don’t think even this burner is getting hot enough, but it should do from everything I’ve read. It took ages to prepare the crucible with borax, although eventually that worked.
The silver is moving around and looking like mercury but it takes about 20 mins to get to that stage, and cools before it pours even though I’m heating the lip. I’m outside but under cover and it’s not windy and I’m using a barbecue cover for protection, and some firebricks next to it. Could the burner or regulator be partly blocked somehow? How would I check? I know the hottest part of the flame is just at the end of the blue zone, but the only way I can get any melting is by having the burner tip almost inside the crucible.
Any suggestions are welcome!
Thanks
