What should I do in this case?I need to stick two pieces of acrylic face to face eg ||>||. I dont want it to fog up.

You should sand a flat spot on the sphere, then use the solvent. That is the better solution.

Crazing can still happen on glued but fully cured joints. If you want no chance of crazing don't flame polish but buff instead.

Yeah! I use propane and oxygen. If you don't flame polish correctly the edge will craze and crack.

Crazing happens if you glue after flame polishing. Always glue first, allow to dry, then flame polish.

Weld On #16 is designed for filling gaps or when there is little contact area, such as gluing a sphere to a flat surface. Otherwise, regular acrylic cement is definitely preferred.

A good glue joint is water tight and safe for fish if allowed to cure for 7 days before adding water. Make sure the tank walls have proper support and are thick enough to withstand the weight of water.

And enjoy that crazed edge when using map gas to polish, and stress the plastic.

Weld On #16 is nowhere near solvent when it comes to bonding.
