If you wish to determine the value of your glass piece, you may want to consult a reliable local antique dealer, or send a photograph of the object to a reputable auction house (see ArtNet’s directory of auction houses worldwide, http://www.artnet.com/auctionhousedirectory/index.aspx). A good place to determine value is also http://www.ebay.com, since there is quite a bit of Pyrex sold there. If you do a search on primary color mixing bowls Pyrex, you should see several auctions. Of course the price is going to depend on condition, age, etc. http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR3.TRC1.A0.H0.Xprimary+color+bowls+pyrex.TRS0&_nkw=primary+color+bowls+pyrex&_sacat=0
You can find appraisers through several professional organizations: The American Society of Appraisers (phone) 1-800-ASA-VALU (online) http://www.appraisers.org; The Appraisers Association of America (phone) 212-889-5404 (online) http://www.appraisersassoc.org; and The International Society of Appraisers (phone) 312-224-2567 (online) http://www.isa-appraisers.org.
Your local library may have a subscription to Maloney’s Antiques and Collectibles Resource Directory, which provides listings of appraisers by type of collectible.
Unfortunately, as a non-profit, cultural institution, the Museum cannot offer appraisal services, but I hope I've given you some leads. As to your other question, no, the colored Pyrex is not sold today. You can see the Pyrex available if you go to the World Kitchen website. World Kitchen currently produces and sells Pyrex today in the U.S.
Good luck with your bowls! They are so classic!
