Thanks for the info. concerning the tooth cavity. I never knew they made a cavity repair kit... Question--{{ I'm using my small silver brewer--- 4 9V batteries-- resistor & meter to make 8 oz. of CS/ EIS . I find it brews faster if I heat the DS H2O in the microwave first. I remember I did ask the list about that & members said it was OK but not to go over 120 degrees....}} Is it ok to seed the DS H2O with some of the silver I have already made??? I use the laser light & I can see a red line when the brewing starts. I'm not sure if it will brew correctly & make good CS/EIS. It sure brews a lot faster. Am I making a mistake???? Thanks for any help you can give...Lois **************Looking for love this summer? Find it now on AOL Personals. (http://personals.aol.com/?ncid=emlcntuslove00000003)
