Help from artists here?

What’s up.

First time posting here, I’m wondering if there are any artists who can share some know how.

A little story: last year, my 20 year old sister made me this DOOM mask for christmas (pictured). It was perfect. Unfortunately, it broke on the flight home (also pictured). It was made of air dry clay, so it was really brittle and I wasn’t careful enough with it. Anyway, a couple weeks later I had this really vivid dream, where DOOM came into my house and looked at the mask and said “this is dope, you gotta fix this.” I tripped out because this dream wasn’t like others, it was like I was awake.

Anyway, 6 months later my sister who made this for me was killed in a traffic accident. It’s been horrible. I feel like fixing this mask is something I’ve gotta do now, like I have instructions. Problem is, I have tried super glue, rubber cement, and Elmer’s glue (some advice online said that this works on air dry clay). None have held so far. So I am wondering if anyone is an artist here who might have a recommendation of what to try. Thanks in advance. Peace.
