vintage Pilgrim art glass pitchers, hand blown amber crackle glass, mottled white

Lot of two 1970s vintage Pilgrim art glass pitchers, hand blown glass decorative pieces in excellent condition.

The taller (crackle glass) pitcher is about 7 1/2" in height, and has no label.

The smaller pitcher (the one with the label) is about 4" tall, and has a mottled pattern in white on amber. I'm not sure what this glass technique is called? It's very pretty!
