My suggestion when running any lamp that's new to you; run it normally (6 to 8 hours) for several days to see if it is okay. I usually give a lamp a week of running to decide if it's good or not.
I just bought a new lamp Saturday and have been running it daily, tonight is the 6th run. It hadn't been running to my satisfaction, but tonight it is flowing fine.
Sometimes if a lamp hasn't been used for a while it can take several runs for the wax to fully melt together, but sometimes it is a lost cause.
Long story short, give it a week (depending of sellers return policy) and if still not satisfied ask for a refund.
i've seen this happen in globes that are stored for long periods of time. i agree with keith to run the lamp for 6-8 hours per day to see if the white chunks will assimilate. in my experience they usually do not, so be prepared.
no problem at all. if everything else is OK, would it be possible for you to 'fish' the white pieces out?
i agree, unless you have to pay return shipping. i've asked for a discount on lamps before because they weren't represented correctly, and that worked. keep checking ebay and hopefully you'll find your perfect lamp someday!
One of the easiest fixes is to replace the wax and fluid from a donor lamp. That might be something to consider if circumstances leave you with a refund AND the lamp.
Jumping in here a little late. Ordered my first Mathmos off ebay, factory new from the UK, Im in the US and the wax started out great the first two days but now has these white bits in it like OP. I am going to trying running it for 6/8 hours and hope this clears up. I really like this lamp and hope I don't have to return it :(.
So I ran the lamp over night and the specks are gone. I turned the lamp off and turned it on again a few hours ago. There are fewer specks than last night, I'm only about 3/4 hours into this run so I am going to keep this cycle up for a few more days and hopefully they will be gone for good.
I live up in the mountains and we do get some cold weather up here. Could it be the cold causing it?
