Return to Nasty Ash

We are mid-renovation in the basement bathroom but I am going to hold you on the edge of your seat.  Yes, the shower is almost complete, but i like shock value.  In fact, I will revise that and say that I am a huge fan of shock value.  Therefore, I will show you the inordinately entertaining photos of demolition.  And it WAS as fun as it looks.  First if you will recall the horror I purchased.  Ugh. Gross.

When we started tearing stuff out we found this:

Anyone have any ideas what it could be?? We were at a loss.  But in a 40 year old house there is no end to the possibilities.  So, we had to resort to the good old N95's.  It's a mask similar to a respirator for those of you who have never worked with harsh chemicals or TB patients.

Yep, I like to kick down walls in my spare time.  In flip-flops.

Unfortunately, the jackhammer was so loud I did not document the removal of the concrete base of the shower.  Sincere thanks to my wonderful father.
