Method of producing two tone dishes and the like

Claim 1

A METHOD OF FORMING TWO-TONED THERMOSETTING ARTICLES OF CONCAVO-CONVEX FORM HAVING A BASE PORTION AND AN ENCIRCLING CONCAVE WALL TERMINATING IN A MARGINAL LIP, BY THE USE OF A MOLD INCLUDING A MALE DIE AND A FEMALE DIE PROVIDING, WHEN CLOSED, A MOLD CAVITY THEREBETWEEN, THE FEMALE DIE HAVING A BASE AREA AND AN ENCIRCLING PERIPHERAL CONCAVE WALL SURFACE HAVING CROSS-SECTIONAL AREA NORMAL TO THE VERTICAL AXIS WHICH CONTINUALLY INCREASE FROM THE BASE AREA TOWARD THE END OF THE FEMALE DIE, AND THE WALL SURFACE, ON A SECTION THROUGH THE VERTICAL AXIS OF THE FEMALE MOLD, CURVING TOWARD PARALLEL RELATION WITH THE VERTICAL MOLD AXIS TOWARD THE END OF THE FEMALE MOLD, THE METHOD INCLUDING THE STEP OF: PLACING A FIRST AMOUNT OF THERMOSETTING RESIN POWER OF ONE COLOR BETWEEN THE MOLD DIES, THE AMOUNT OF POWDER BEING SUFFICIENT TO FILL THE MOLD CAVITY, COMPRESSING THE FIRST AMOUNT OF POWDER BETWEEN THE DIES, FILLING THE MOLD CAVITY UNDER HEAT AND PRESSURE FOR A TIME SUFFICIENT TO PRODUCE A FORMED ARTICLE HAVING A SURFACE HARDNESS SUFFICIENT TO WITHSTAND A SECOND CASTING OPERATION WITH ADDITIONAL THERMOSETTING RESIN POWDER BUT WHICH TIME IS INSUFFICIENT TO SET THE RESIN, OPENING THE MOLD CAVITY, OVERFILLING THE MOLD CAVITY BY ADDING ADDITIONAL THERMOSETTING RESIN POWDER OF A COLOR CONTRASTING WITH THE FIRST-MENTIONED POWDER AND IN AN AMOUNT SUFFICIENT TO COMPLETELY COVER THE CONVEX SURFACE OF THE FORMED ARTICLE BUT SUBSTANTIALLY LESS THAN SAID FIRST AMOUNT OF POWDER USED TO PRODUCE THE FORMED ARTICLE, CLOSING THE MOLD TO BRING THE SURFACES OF THE MOLDED ARTICLE WALL AND THE FEMALE DIE CLOSER TOGETHER ADJACENT THE LIP OF THE FORMED ARTICLE THAN ADJACENT THE BASE PORTION OF THE FORMED ARTICLE, THEREBY FLOWING A LAYER OF PLASTIC OVER THE SURFACE OF THE FORMED ARTICLE WHICH IS RELATIVELY THICK AT THE BASE PORTION OF THE FORMED ARTICLE AND WHICH IS RELATIVELY THIN AT THE LIP END OF THE FORMED ARTICLE.

Claim 2

A METHOD OF FORMING TWO-TONED THERMOSETTING ARTICLES OF CONCAVO-CONVEX FORM HAVING A BASE PORTION AND AN ENCIRCLING CONCAVE WALL TERMINATING IN A MARGINAL LIP, BY THE USE OF A MOLD INCLUDING A MALE DIE AND A FEMALE DIE PROVIDING, WHEN CLOSED, A MOLD CAVITY THEREBETWEEN, THE FEMALE DIE HAVING A BASE AREA AND AN ENCIRCLING PERIPHERAL CONCAVE WALL SURFACE HAVING CROSS-SECTIONAL AREA NORMAL TO THE VERTICAL AXIS WHICH CONTINUALLY INCREASE FROM THE BASE AREA TOWARD THE END OF THE FEMALE DIE, AND THE WALL SURFACE, ON A SECTION THROUGH THE VERTICAL AXIS OF THE FEMALE MOLD, CURVING TOWARD PARALLEL RELATION WITH THE VERTICAL MOLD AXIS TOWARD THE END OF THE FEMALE MOLD, THE METHOD INCLUDING THE STEP OF: PLACING A FIRST AMOUNT OF THERMOSETTING RESIN POWER OF ONE COLOR BETWEEN THE MOLD DIES, THE AMOUNT OF POWDER BEING SUFFICIENT TO FILL THE MOLD CAVITY, COMPRESSING THE FIRST AMOUNT OF POWDER BETWEEN THE DIES, FILLING THE MOLD CAVITY UNDER HEAT AND PRESSURE FOR A TIME SUFFICIENT TO PRODUCE A FORMED ARTICLE HAVING A SURFACE HARDNESS SUFFICIENT TO WITHSTAND A SECOND CASTING OPERATION WITH ADDITIONAL THERMOSETTING RESIN POWDER BUT WHICH TIME IS INSUFFICIENT TO SET THE RESIN, OPENING THE MOLD CAVITY, OVERFILLING THE MOLD CAVITY BY ADDING ADDITIONAL THERMOSETTING RESIN POWDER OF A COLOR CONTRASTING WITH THE FIRST-MENTIONED POWDER AND IN AN AMOUNT SUFFICIENT TO COMPLETELY COVER THE CONVEX SURFACE OF THE FORMED ARTICLE BUT SUBSTANTIALLY LESS THAN SAID FIRST AMOUNT OF POWDER USED TO PRODUCE THE FORMED ARTICLE, CLOSING THE MOLD TO BRING THE SURFACES OF THE MOLDED ARTICLE WALL AND THE FEMALE DIE CLOSER TOGETHER ADJACENT THE LIP OF THE FORMED ARTICLE THAN ADJACENT THE BASE PORTION OF THE FORMED ARTICLE, THEREBY FLOWING A LAYER OF PLASTIC OVER THE SURFACE OF THE FORMED ARTICLE WHICH IS RELATIVELY THICK AT THE BASE PORTION OF THE FORMED ARTICLE AND WHICH IS RELATIVELY THIN AT THE LIP END OF THE FORMED ARTICLE.
