220.0. "(kosher-p bone-china)?" by CAD::LEVITIN (Sam Levitin) Mon Oct 27 1986 08:57

Does anyone have any reliable knowledge of whether "Bone china" 
is considered kosher; ie, proper to eat from?

My concern stems from an idea that I saw on net.veg, that
"bone china" contains ground animal bones. It is for this reason
that some vegetarians eschew these plates. I would like to avoid
bone china if it is indeed not in line with kashruth.

220.1	Interesting Question.....	TAV02::ALLIN1V2	Le'Chaim	`Tue Oct 28 1986 01:28`	28
	That is a very interesting question and I really don't ever remember hearing it being discussed. Based on the little knowledge that I have, I would tend to believe that it should be ok. Firstly, I would assume that any bone matter being used would have been dried out completely. This the Shulchan Aruch explicitly says is ok. Secondly, depending on the amount of bone matter relative to other component materials might be less than 1/60 of the total thus it is considered negligent. Thirdly, the manufacturing process which I assume mixes the bone matter with all sorts of chemicals will render the concoction inedible and this too would then be ok. Fourthly, the baking process might be considered as having either changed the entire entity into a new entity or as having destroyed the former entity. These are the considerations that have come off the top of my head. These are in NO way meant to be a Psak. I would be very interested in hearing if there has been a reputable (Rav Moshe Ztz'l or Rav Henkin Ztz'l etc.) Psak given. Cb.
