Question mortar mix..

I built my oven using 1 portland cement, 5 lome (sand with clay) and 1 lime. I also used second hand red bricks from a fireplace/chimney. It has been over a week and the dome still smells of mortar. Was this mix and seconds bricks OK?

Not unless that is all you had available.

This mix was recommended by Jussell Jeavons (he wrote a book on ovens) and I assumed it would all be good. Russel recommended brick sand, however all I could get was lome which is a reddish type sand that contains clay which should help to stop too much cracking. I was more worried about the portland cement after reading about the need to use refractionary.

Your mix is essentially the same as the home brew lots of people have used. The loam you used probably contains a fair amount of bacteria which may be contributing to the smell. This will simply burn away once you start firing. I wouldn't be worried at all by a smelly mortar.
