I made a tunnel portal and used plaster-of-paris material. As I was taking it out of my form, it broke ($@*%)! Anyway, it was a very clean break. When I put it back together, you'll never notice the break. Question - what do I use to put the 2 pieces back together? Elmers white glue, capenters glue, hot-glue gun, special porcelain/ ceramic glue, or what?
I guess you will glue the tunnel portal to some type of base like wood. Then I would glue both parts with white glue, carpenters glue to the wood. Without gluing the two parts together. If they are from plaster, you can take a brush and brush plaster powder with a little bit water over the break. Wolfgang
My glue of preference has always been the type of clear goop that you use to glue and seal joins in PVC tubing, such as the 2" kind used for built-in vacuum systems. I have used this methyl-ethyl ketone (MEK) product very successfully, enjoying a very strong bond on ceramics. MEK is the main ingredient in your styrene plastic model kit glues.
