Default Here is a really dumb newbie question

Alright, I purchased the boro two years ago I believe. Melted a few mandrels, got disgusted and put it away. Back to it this morning.

So, does boro glass have silver in it? I only ask because I wear a magnifier and I saw this familar haze rolling around on the surface of the glass when in the heat.

Also, do I need to change my annealing schedule for boro?



Also, someone was very kind and shipped me for free some boro frits. I finally tried them this morning. I wish I could remember who you were to thank you again. If you are reading this ,thank you!

some boro colors have silver, but not all.

As for annealing what I use for most stuff is:
hold at 1050, 15 minutes per 1/4 inch of thickness
Ramp slowly down to 700ish
Let it fall to room temp on it's own.
