Hi Aki,
<div><br></div><div><span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; "><div>Since  </div><div>Question 1 : Since the CRT is a vacuum, if subjected to sudden physical shock, will it implode or explode?</div>
<div>Answer: Implode.</div><div> </div><div>Question 2 : Why is the front of CRT screen thicker ( at least 1 inch ) while the rest is delicate glass?</div><div>Answer: There is an aquadag coating that is not present anywhere else and its only the front that is being &#39;hit&#39; by accelerated electrons.</div>
<div> </div><div>Question 3 : Is it true that the phosperous material can get magnetised and change colour display and what is the remedy?</div><div>Answer: Presence of strong EMF derails the electrons from their path hence discolouration. Most modern CRT circuits have a degauss circuit which is responsible for rectifying this. Degauss and your colour comes back.</div>
<div><br></div><div>Regards</div></span></div>
