Hi everyone,
I recenty uncovered from the lower Maastrichtian chalk of Moens Klint a partial but articulated Isselicrinus buchii columnal fragment (15 segments), which also preserves one complete cirrus (one of the many side arms of a crinoid - rare at M. K.). Today, 2 out of 5 of the plates of the cirrus dislodged themselves from the matrix and came loose. What type of glue must I use to fix them back (most efficient and cheap possible)?
Best,
Christian
