I have been bottle carbonating for the last 10 days. The temperature has been fairly consistent, between 17 - 20. I can see a little sediment, which suggests fermentation, but I can't see any bubbles, is this normal?

No bubbles in an unopened bottle? Sounds normal to me. I noticed the same thing in my first batch, but when I tried one, it was nicely carbed. – CDspace Feb 17 '14 at 16:04
Exactly what I wanted to hear! – Mild Fuzz Feb 17 '14 at 16:06
The sediment may just be trub settling, which may contain yeast, but other things as well (proteins, fats, other heavy materials). – Wyrmwood Feb 17 '14 at 22:48

Yes, perfectly normal. It may be done carbing or it may take a few more days.

how do you know when it is done? – Mild Fuzz Feb 17 '14 at 16:11
You chill one, open it, and taste it! – Denny Conn Feb 17 '14 at 17:30

You'll like the beer more. – DesertIvy Feb 17 '14 at 21:42
One suggestion I heard of, to keep track of carbonation was at the same time as you bottle all of your beer, fill a 500ml plastic bottle leaving a normal gap. Squeeze the bottle so that the beer is level with the brim of the opening. Put the lid on and place it with the rest of your carbonating beer. As the gasses are produced this bottle will gradually expand showing you the progress of the carbonation. – Amos Feb 17 '14 at 22:00
