00:00In 2018, around 2018, Indian Space Research Organisation, and it's called Vikram Sarabhai

00:11Space Centre specifically, they have approached us to develop five varieties of optical glasses,

00:18spade-gate optical glasses of stringent quality, stringent quality means they have mentioned

00:24this is the transparency level, this is the homogeneity of the glass, this is the refracting

00:28there are five, six, seven, eight parameters has to be made, right? So the problem is that if you

00:34meet, suppose if I have matched, the transparency will be there. Transparency I have matched,

00:40something is getting quality. So meeting all the parameters simultaneously is a very challenging

00:45job. So they have given us five, to develop five variety of optical glasses, that all the five

00:51optical glasses we have developed successfully, we have supplied to the store, and they are using

00:57those materials. Now we are extending the project, they are actually approach that,

01:04okay you have done five glass, you have to develop another series of glasses, that is

01:09needed for the space car, for Indian space network. And because, why we are doing, because

01:15they are buying it from short Germany, they are costing exorbitantly high cost, and also the

01:21availability issue, they can stop you anytime, right? So India is basically very,

01:27it is a third in the world, you can say in the space research, right? Space research,

01:32we are at the above many countries, advanced countries. So we are basically giving satellite

01:37to other people. Our launch vehicles are used for launching satellite of other countries, right?

01:43So commercially we are basically getting from them. So this is a strong mission, space mission,

01:49and we need to support, we need to self-reliant. So five variety of optical glasses we have

01:54developed, they are now approaching to develop some more glasses, and ultimately that we will

01:59be developing. And the requirement is also coming up. So they found that we are confident,

02:05we can do that, CGCR can do that. So Germany is also doing this. Yes. Plus we are saving the cost.

02:11And the glasses that we are making here, this is under the brand image of CGCR.

02:16And the glasses that we are making, they should know by one operator, where the glass,

02:21the curtain opens and the glass comes out, at that time they should know that this is the

02:25brand name of CSIR, Central Glass and Ceramic Research Institute, and this is in India.

02:30Not this glass is from abroad or any other, we are India.
