is it safe to use on a glass coffee carafe ?

Asked by: popeye
It is aquarium safe, so it should be, however in the product description someplace, it had that it was acceptable for, what was the phrase? It was something like temporary food placement. It was an odd statement because I thought that since it is aquarium safe it would be food safe. But, look at the product description somewhere for something about this to clarify what I'm telling you.

Can you glue glass to glass (looking to glue glass candlesticks together) with this?

Asked by: Glassloser
DAP Silicone Aquarium Sealant be used to edge bond glass assemblies, however, entrapped applications (material applied between nonporous materials, with little to no air contact), will be very slow to cure and develop performance.

2.8 oz. Silicone Aquarium Sealant is rated 4.3 out of 5 by 13.
Rated 4 out of 5 by from I would buy this again & provide my own cap. I have used DAP products my whole life. As a sealant they are the best; however, after I sealed my coffee carafe, which used only a tiny bit, I realized, there was no way provided to close the tube or nozzle to prevent the whole tube from drying out before the next use. Fortunately, I have had this problem before with manufacturers who failed to "think it through" and simply used a wire connector on the nozzle. I would expect more from such a professional company. Just make sure to have a mediumse size wire connector handy before opening the tube, Otherwise, it gets 5 stars.

Rated 4 out of 5 by from silicone This product sealed great and was easy to use. The only problem I had is the tube was difficult to squeze and seemed to work better if i rolled the bottom of the tube up.

Rated 5 out of 5 by from works well, great price Finally I found some aquarium grade silicone glue at a decent price. Works great. I did not want to chance my fish to regular silicone glue.

Rated 4 out of 5 by from Larger Tube Great stuff, but would be easier to seal a larger tank if the tube was bigger and fit into a caulking gun.
