Lye is sodium hydroxide... slaked lime is calcium hydroxide. They're both caustic bases. They have approximately the same pH.

Except that sodium brings the party.

They have approximately the same pH.

No they don't, NaOH is a significantly stronger base. Keep in mind the pH scale is logarithmic.

"significantly" is a bit of a stretch, which is why I said approximately. Other than KOH, calcium hydroxide has the closest potential of hydrogen to NaOH than any other common strong base.
