Glass paperweights

Would it be safe to put glass paperweights into the aquarium? The kind with all the clorful designs in them. Is there a way to test them like you can rocks?

Thats heated cooked glass its going to be completely inert. just make sure you clean it off and it doesn't have any sharp edges

I was thinking a cave somewhere in the tank and one of those paperweights in the very back of the cave. Not really the center of attention, but something to see when your looking in the cave. Something to make you say "wow, what is that". Does that give you an idea of what I was thinking?

It's not THAT dumb. It depends on what kind of glass it is!

Safety

Leaded crystal wineglasses and decanters are generally not considered to pose a significant health risk, provided that these items are washed thoroughly before use, that beverages are not stored in these containers for more than a few hours, and provided that they are not used by children.[11][12]
It has been proposed that the historic association of gout with the upper classes in Europe and America was, in part, caused by their extensive use of lead crystal decanters to store fortified wines and whisky.[13] Lin et al. have statistical evidence linking gout to lead poisoning.[14]
Items made of lead glass may leach lead into the food and beverages contained.[15][16] In a study performed at North Carolina State University,[17] the amount of lead migration was measured for Port wine stored in lead crystal decanters. After two days, lead levels were 89 g/L (micrograms per liter). After four months, lead levels were between 2,000 and 5,000 g/L. White wine doubled its lead content within an hour of storage and tripled it within four hours. Some brandy stored in lead crystal for over five years had lead levels around 20,000 g/L.[18][19] To put this into perspective, the U.S. Environmental Protection Agency's lead standard for drinking water is 15 g/L = 0.15 parts per million.[20] Citrus juices and other acidic drinks leach lead from crystal as effectively as alcoholic beverages. When lead-glass beverage containers are used in the ordinary usual way they do not pose a health risk.[21][22] Under conditions of repeated use of the decanter, the lead leaching steeply decreases with increasing use. This finding is "consistent with ceramic chemistry theory, which predicts that leaching of Pb from crystal is self-limiting exponentially as a function of increasing distance from the crystal-liquid interface."[22] Lead leaching still occurs, but the quantity that leaches into a glass of wine or other beverage let stand for a few hours is much smaller than the quantity of lead consumed daily in ordinary diet. An ordinary diet contains about 70 g of lead per day.[21]

I agree with planted. you just need to make sure that you clean it off and it does not have any sharp edges.
