Just wondering... do you ever need to replace annealing bubbles? Do they get less effective over time? Or will they go on forever?!
Good question, if they do then they are a bargain.
They don't go off !Being silica based they will crumble over time and blow awauy but apart from that they should last a long time .
mine have lasted for ages so far ( they would do even better if little fingers didnt keep squashing them!)
vermiculite always went a bit dusty but the bubbles have stayed round ;D
Are they supposed to / able to go in a slow cooker like Vermiculite?

They can but there is no need as they cool 3 x more slowly than the vermiculite :)
ok thanks Manda
I hope you don't mind me asking....but is the crumbled bubble dust a health problem since it's silica based?
It sinks to the bottom so on a day to day basis I would say not - certainly not in comparison to vermiculite . Vermiculite gives off a certain amount of dust when you push your mandrel in - annealing bubble is very clean in comparison . The dust will accumulate at the bottom of your container so just be careful when you dispose of it which shouldn't be for a long time.Hope that helps xx
