"that assist in classifying pots"这一部分是定语从句部分,用来修饰Long descriptions .
that assist in classifying pots的中文解释是：有助於分别 / 区别不同的瓷器类型.
这个从句部分放在exist的後面是为了避免这个整句的头重脚轻：
Long descriptions of the different types of ware that assist in classifying pots exist,although- - --.(exist在後面,句子显得不平衡,头重脚轻.)
你的句子也可以,并且最好这样rewrie :
There exist long descriptions of the different types of ware that assist in classifying pots,although -- - -.

"that assist in classifying pots" 是修饰最前面"Long description"， 也就是说 Long description “帮助对pots的分类“。 这里"pots" 没有太多的上下文， 可能指锅碗瓢盆一类的pots， 也可能指陶瓷类的pots。
这句话其实是因为主语太长， 所以把动词"exist"嵌在中间，另一个原因是如果把 "that assist in classifying pots" 放在 "ware" 后面的话就造成语义歧义。
我的中文不是很流利， 望见谅。

看见palmaking的回答， 不完全正确。 'that assist in classifying pots' 不是修饰'ware'。 语义不通。

这句句子里的'that'不起强调作用， 是主语定语的必须辅助词。 'that‘在宾语从句中可以省略， 但是在这里做主语用不能省略。 如：
The idea that helped me solve this problem was very useful: 'that' 从句修饰主语 'the idea', 不能省略 'that'
The idea (that) you gave me helped me solve this problem: 'that'从句是宾语从句， ‘that'可以省略。
