Obviously, twin scaling of a virused bulb will produce virused bulbs. My point was that twin scaling of a large virused bulbs will produce numerous small virused bulbs. As people pointed out, small bulbs may be more easily heat treated than large bulbs. Also, having numerous small virused bulbs instead of one large virused bulb allows you the opportunity to try more than one temperature or heating duration. This may give you a better chance of saving some large infected bulb. Nathan At 04:11 PM 5/9/2013, you wrote: >Wow, this is shrapnel!
