Bobcat centerfire should run great on a 20. But it is still not a super hot flame compared to bigger torches, and a concentrator will never give you what tanked will. I don't know about your sodium flare question though. I thought boro was not a sodium glass - it is silica and boron. Are you getting good results on your colors that require oxygenation?
