Guest guest Posted October 2, 2005 Report Share Posted October 2, 2005 Respected Shri.Richard ji, Thank you very much for your mail. As you know, the shape of Whelk is totally different than that of the Turbinella pyrum. It is true that the diagnostic character to differentiate in Whelk and Turbinella pyrum is the presence of 3 to 5 pilae or ridges in the conch cavity. However, now a days I have seen people making making fake Valampuri from that of Whelk by artifically pasteing three ridges made either from plaster of Paris (POP)or by cutting and pasteing of ridges from other normal left handed conch. People, who only go by characters of presence of ridges in the cavity are thus fooled. Of course, by experienced eye one can identify the original ridges and pasted ridges easily. In conch species there is much variation, therefore I have developed a technique to take X-Ray images of conch. X-Ray dose rate differs from conch to conch depending on the type of conch and quantity of deposition of calcium compounds and of metallic elements in conch, type of X-Ray machine and the type of X-Ray film used. The conch pilae or ridges are like screw threading coiling around the columella and is clearly seen in X-Ray image. If you see X-Ray image of the Whelk or any conch which do not show the character of presence of pilae show plain columella. Fake and real can easily be determined by X-Ray. In a day or two I will send you the information of the website in which beautiful X-Ray images of variety of conch species have been displayed. The X-Ray image of whelk shows plain columella, however, on internet no X-Ray image of Valampuri is available. I am developig a website on Valampuri and planning to keep X-Ray images on it. However, sometimes it is difficult to scan X-Ray images. I provide X-Ray image of the Valampuri conch to my customers. Thanking you and with personal regards, Chandrashekhar Phadke Quote Link to comment Share on other sites More sharing options...
