Best Quality Glass

Hi friends
I took my parents out for dinner a couple of days back. As i was sipping my drink, a thought occured to me. "Where do the glasses come from? How are they manufactured? Where do you find the best quality glass?I decided to take a look in the internet to find the answers to my questions.
First of all, i learnt a new term - GRP. GRP means glass reinforced plastic. This is one special blend of plastic which is produced in this Log Store. I have given a direct link to the site so that you all can experience the whole process first hand.
As regards to my final question of where to find the best quality glass fibre , it is here at this wonderful site called harviglass group.
